We can all agree that science is awesome. And you can bring that awesomeness into your very own home with these 20 safe DIY experiments you can do right now with ordinary household items.

1. Make Objects Seemingly Disappear Refraction is when light changes direction and speed as it passes from one object to another. Only visible objects reflect light. When two materials with similar reflective properties come into contact, light will pass through both materials at the same speed, rendering the other material invisible. Check out this video from BritLab  on how to turn glass invisible using vegetable oil and pyrex glass.

2. Freeze Water Instantly When purified water is cooled to just below freezing point, a quick nudge or an icecube placed in it is all it takes for the water to instantly freeze. You can finally have the power of Frozone from The Incredibles on a very small scale! Check out the video on this "cool" experiment. 

3. Create Oobleck And Make It Dance To The Music Named after a sticky substance in a children’s book by Dr Seuss , Oobleck is a non-Newtonian fluid, which means it can behave as both a solid and a liquid. And when placed on a sound source, the vibrations causes the mixture to gloopily dance. Check out these instructions from Housing A Forest  on how to make this groovy fluid funk out in every way.

4. Create Your Own Hybrid Rocket Engine With a combination of a solid fuel source and a liquid oxidizer, hybrid rocket engines can propel themselves. And on a small scale, you can create your own hybrid rocket engine, using pasta, mouthwash and yeast. Sadly, it won’t propel much, but who said rocket science ain’t easy? Check out this video from NightHawkInLight on how to make this mini engine.

5. Create "Magic Mud" Another non-Newtonian fluid here, this time from the humble potato. "Magic Mud" is actually starch found in potatoes. It’ll remain hard when handled but leave it alone and it turns into a liquid. Make your own “Magic Mud” with this video.

6. Command The Skies And Create A Cloud In A Bottle Not quite a storm in a teacup, but it is a cloud in a bottle. Clouds up in the sky are formed when water vapor cools and condenses into visible water droplets. Create your own cloud in a bottle using a few household items with these wikiHow instructions .

7. Create An Underwater Magical World First synthesized by Adolf van Baeyer in 1871, fluorescein is a non-toxic powder found in highlighter pens, and used by NASA to find shuttles that land in the sea. Create an underwater magical world with this video from NightHawkInLight .

9. Make Your Own Lava Lamp Inside a lava lamp are colored bubbles of wax suspended in a clear or colorless liquid, which changes density when warmed by a heating element at the base, allowing them to rise and fall hypnotically. Create your own lava lamp with these video instructions.

10. Create Magnetic Fluid A ferrofluid is a liquid that contains nanoscale particles of metal, which can become magnetized. And with oil, toner and a magnet , you can create your own ferrofluid and harness the power of magnetism! 

12. Make Waterproof Sand A hydrophobic substance is one that repels water. When sand is combined with a water-resistant chemical, it becomes hydrophobic. So when it comes into contact with water, the sand will remain dry and reusable. Make your own waterproof sand with this video .

13. Make Elephant's Toothpaste Elephant’s toothpaste is a steaming foamy substance created by the rapid decomposition of hydrogen peroxide, which sort of resembles giant-sized toothpaste. Make your own elephant’s toothpaste with these instructions.

14. Make Crystal Bubbles When the temperature falls below 0 o C (32 o F), it’s possible to freeze bubbles into crystals. No instructions needed here, just some bubble mix and chilly weather.

15. Make Moving Liquid Art Mixing dish soap and milk together causes the surface tension of the milk to break down. Throw in different food colorings and create this trippy chemical reaction.

16. Create Colourful Carnations Flowers absorb water through their stems, and if that water has food coloring in it, the flowers will also absorb that color. Create some wonderfully colored flowers with these wikiHow instructions .

17. "Magically" Turn Water Into Wine Turn water into wine with this  video  by experimenter Dave Hax . Because water has a higher density than wine, they can switch places. Amaze your friends with this fun science trick.

18. Release The Energy In Candy (Without Eating It) Dropping a gummy bear into a test tube with potassium chlorate releases the chemical energy inside in an intense chemical reaction. That’s exactly what's happening when you eat candy, kids.

19. Make Water "Mysteriously" Disappear Sodium polyacrylate is a super-absorbent polymer, capable of absorbing up to 300 times its own weight in water. Found in disposable diapers, you can make water disappear in seconds with this video .

20. Create A Rainbow In A Jar Different liquids have different masses and different densities. For example, oil is less dense than water and will float on top of its surface. By combining liquids of different densities and adding food coloring, you can make an entire rainbow in a jar with this video .

There you have it – 20 experiments for you to explore the incredible world of science!

37 Cool Science Experiments for Kids to Do at Home

General Education

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

• Teaches Kids About: Zoology
• Difficulty Level: Medium
• Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

• Materials Needed
• Shadow box or other box with multiple compartments
• Hot glue gun with glue
• Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

#2: DIY Lava Lamp

• Teaches Kids About: Chemical reactions
• Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

• Vegetable oil
• Food coloring
• Antacid tablets

#3: Magnetic Slime

• Teaches Kids About: Magnets
• Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

• Liquid starch
• Adhesive glue
• Iron oxide powder
• Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

• Teaches Kids About: Chemical reactions, earth science
• Difficulty Level: Easy-medium
• Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

• Baking soda
• Dishwashing detergent
• Large mason jar or soda bottle
• Playdough or aluminum foil to make the "volcano"
• Additional items to place around the volcano (optional)
• Food coloring (optional)

#5: Tornado in a Jar

• Teaches Kids About: Weather
• Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

• Glitter (optional)

#6: Colored Celery Experiment

• Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

• Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

• Glass jar with a lid
• Boiling water
• Aerosol hairspray

#8: Edible Rock Candy

• Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

• Large saucepan
• Clothespins
• String or small skewers
• Candy flavoring (optional)

#9: Water Xylophone

• Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

• Wooden sticks/skewers

#10: Blood Model in a Jar

• Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

• Empty jar or bottle
• Red cinnamon candies
• Marshmallows or dry white lima beans
• White sprinkles

#11: Potato Battery

• Teaches Kids About: Electricity
• Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

• Fresh potato
• Galvanized nail
• Copper coin

#12: Homemade Pulley

• Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

• Clothesline
• 2 clothesline pulleys

#13: Light Refraction

• Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

• Sticky note
• Transparent water bottle

#14: Nature Journaling

• Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

• Blank journal or notebook
• Pens/pencils/crayons/markers
• Tape or glue for adding items to the journal

#15: DIY Solar Oven

• Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

• Aluminum foil
• Knife or box cutter
• Permanent marker
• Plastic cling wrap
• Black construction paper

#16: Animal Blubber Simulation

• Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

• Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

• Tissue paper
• Thick paper
• Glue stick/glue

#18: Edible Double Helix

• Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

• 2 pieces of licorice
• 12 toothpicks
• Small marshmallows in 4 colors (9 of each color)
• 5 paperclips

#19: Leak-Proof Bag

• Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

• Zip-lock bags
• Objects with sharp ends (pencils, bamboo skewers, etc.)

#20: How Do Leaves Breathe?

• Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

• Large bowl (preferably glass)
• Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

• Popsicle sticks
• Rubber bands
• Plastic spoons
• Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

• Clean 16-oz soda bottle
• 6% solution of hydrogen peroxide
• 1 packet of dry yeast
• Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

• Penguin image (included in link)
• Spray bottle
• Blue food coloring (optional)

#24: Rock Weathering Experiment

• Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

• Plastic wrap

#25: Saltwater Density

• Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

• Four clear glasses
• Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

• Toaster oven

#27: Inertia Wagon Experiment

• Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

• Stack of books

#28: Dinosaur Tracks

• Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

• Used coffee grounds
• Wooden spoon
• Rolling pin

#29: Sidewalk Constellations

• Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

• Sidewalk chalk
• Small stones
• Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

• Plastic bottle
• Rubber band

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

• Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

• Clay or gumdrops (in four colors)
• Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

• Straws (paper work best)
• Twine or yarn

#34: Solar Energy Experiment

• Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

• 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

• Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

• Pencil with eraser
• Aluminum tray or pie tin
• Styrofoam tray

#36: Tie-Dyed Milk

• Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

• Shallow dish
• Milk (high-fat works best)

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

• Safety pins
• 2 glass jars

Summary: Cool Science Experiments for Kids

Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child's specific interest or what they're currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Science Experiments at Home that take Less than 1 Hour

1. tie-dye milk.

Sounds delicious, right? You’re not actually drinking it, but instead watching science magic happens when you combine dish soap with milk and food coloring. This is a very pretty experiment that draws the focus and mind into what’s happening on the plate, and all because of a little chemistry with everyday items. Well, food dye may not be an everyday item, but it might be after your kids get a hold of this!

So, what’s going on here, scientifically-speaking? Milk is made up of two major ingredients: water and fat. When you add a little dish soap, it bonds with the fat in the milk so strongly that it literally pushes the food coloring and water away from the cotton ball. On a microscopic level, the dish soap is wandering around the milk, which causes the colors to swirl and swirl.

Questions to ask beforehand:

• Before knowing what will happen to the food coloring, ask the kids what they think will happen when dish soap mixes with milk.
• Since the major catalyst is fat in the milk, what would happen if you used other types of milk: Skim milk, soy milk, coconut milk?

You’ll need:

• Round cake pan or plate with high edges
• Cotton ball (some tutorials show cotton swabs)
• Dish detergent
• Different colors of food dye (three or four should do)

Procedure/Instructions:

• Fill the pan halfway with milk.
• Drip one color of food dye in one section of the plate away from the center. Four to five drops works and later you can play around with more or less. Do the same for the rest of the colors around the plate.
• Soak the cotton ball in dish detergent, and when you’re ready for action, place the cotton ball into the center of the pan.
• Watch the colors racing around, creating a psychedelic tie-dye effect!
• You can add more cotton balls throughout the dish to see more action.
• If some food coloring hugs the wall of the plate, take a cotton swab dipped in dish detergent and place it into the food coloring. It will move away!

2. Saturn’s Glowing Rings

I don’t know about you, but I love everything about space. This experiment shows you how Saturn’s rings are made of rocks and ice chunks even though they look so smooth in pictures. You’ll also see why there are big gaps in the rings. Younger kids take delight in using a flashlight and sprinkling powder, while older kids can get more specific with questions about Saturn and how the rocks and ice stay in orbit.

• Do Saturn’s rings give off their own light?
• Why are some rocks and ice chunks more lit up than others?
• Compare the results of light sprinkles to thicker sprinkles.
• Strong flashlight
• Powder (flour, baby powder, etc) in a shaker
• Very dark room
• Darken a room and set the flashlight on the edge of a table or counter, pointing it at a blank wall. Lay the newspaper on the floor between the flashlight and the wall.
• Turn on the flashlight and notice where the light comes from the flashlight and where it hits the wall. You should only see the light from these two places and not from the space between them. This shows you that the light travels through the air without being seen until it hits the wall. The light represents the sun’s light.
• Now to see how Saturn’s rings glow: Hold the powder shaker and sprinkle some powder over the beam of light where you know the light is traveling. You’ll notice the powder lights up and sparkles in the beam of light. The powder shows in glowing clumps, just like in Saturn’s rings.

3. Breaking Down Colors

We all know that the fun, vibrant colors we see in our lives are created by mixing the basic red, yellow, and blue. In this experiment, you and your child will learn which colors make up those fun shades they have in their art supplies. This also teaches some basic chemistry and uses materials you already have at home. It can be done very simply and expanded to create a large-scale investigation if you love it.

• Which colors separate out first?
• Is the same order for each test?
• Which colors make up the original shade?
• Do the different types of color (pen, pencil, paint) separate in the same way or differently?
• Are some separated in a shorter space are the colors the same mixture?
• Coffee filters
• Color sources (markers, colored pencils, paint, etc.)
• A plain pencil
• To complete this experiment, cut the coffee filters into strips, mark one end with a line the same distance from the bottom on each strip.
• Color in each strip (between the bottom and line) with your colors, and write at the top what the color and source are (e.g., purple marker).
• Place each strip in a glass and help it to stand up by folding the top over a pencil (a chopstick, table knife, or any long narrow object will also work) so that it stands up in the glass.
• Fill the glass up to the top of your colored block, and wait. The water will move up the filter, and the colors will separate out as it goes.
• Remove the strip once the water gets near the top of the strip to stop the experiment. 

To make this a true experiment, we recommend testing multiple colors and using markers, colored pencils, and paint (as some starting examples). You could test the same colors from each type of art supply to investigate whether they all use the same mix of basic colors to create the same end product.

This post has a nice full description of the methods if you need more detail.

4. Water Xylophone

This simple experiment will teach your child about sound and pitch using glasses, water, and something to act as a mallet. Don’t let the simplicity deceive you, there are a lot of ways to experiment and learn through this process, and it also brings in an element of music that makes it interesting and engaging.

• Do you think more water makes the sound higher or lower in pitch?
• How do you think the shape or size of the glass will affect the sound?
• How should we arrange the glasses to play a simple song?
• Do you think this will work with a plastic cup, why or why not?
• Some glasses
• Something wood to act as a mallet (we recommend wood so you don’t break the glasses!)
• A great way to start is with glasses that are the same size, shape, and material, and filling them with different amounts of water.
• Have your child use the mallet to test how the amount of water affects the sound.
• From there, it’s a really simple extension to use different sized and shaped glasses (or any glass vessel like jars and bowls) to experiment with how the shape, size, and amount of water in the glass affect the tone. 

To take this one further and really bring in the musical component, you and your child could work out a simple song and create the right tones to play it. If you or your child are musical, you could get very elaborate and creative (try googling harry potter or star wars theme songs on glasses, there are so many options that I couldn’t even choose one)!

5. Ultimate Bottle Flipping

Ah, bottle flipping. The fad that kids can’t get enough of, but parents are well and truly over. The constant thud of semi-filled water bottles being tossed (and hopefully landing upright) is guaranteed to send parents around the twist!

If you can stand it for a bit longer though, there’s a lot of STEM knowledge to be gained in this bottle flipping experiment. As we know, the aim of bottle flipping is to flip a partially filled water bottle underhand and get it to land upright.

In this experiment, kids will learn the importance of observing a result multiple times before changing a variable (the amount of water in the bottle).

• How much water should you put in the bottle?
• What is the ideal amount of liquid to get the perfect flip?
• What should be the ideal amount of water?
• Was their prediction correct?
• Why do they think the amount of water affects the chances of landing the bottle?
• A plastic water bottle
• Measuring jug
• Paper to record results
• Get the kids to start by flipping their bottle with no water in it at all. Kidspot recommends flipping it 50 times for each step, but you could do less if you need to.
• Try it again with 50ml of water.
• Keep adding more water until the bottle is full.

If they’re keen, you could try other types or sizes of bottles, or even try different liquids to see if that affects the results!

6. Rainbow in a Jar

This simple science experiment is not only very visually appealing, but it’s also a great way to learn about the density of liquids. Warning though, this one could get messy so make sure kids are in some old clothes and you might want to take it outside! I like this experiment because you’ll probably have most of the materials in your kitchen already!

• Which liquids they think will be heaviest?
• Which ones will be lightest?
• Why do they think that?
• A glass jar
• Food coloring
• Various liquids like honey, corn syrup, dishwashing liquid, olive oil, rubbing alcohol and water.
• Use the food coloring to make all your liquids a different color. A dropper comes in handy here, but if you don’t have one you can manage without.
• Slowly add each liquid to the jar (pouring into the middle of the jar is best).
• Soon, you’ll have different layers of colored liquid forming your very own rainbow in a jar.

You might even get them to draw a diagram of what they think the jar will look like at the end. They can compare this with the experiment results to see if their prediction was correct.

It might also help to talk to your kids first about what density is and how materials are all made of different amounts of molecules. The more molecules a liquid has, the heavier it will be. Playdough to Plato demonstrates a great way of introducing this concept using marbles. 

7. Write Your Own Secret Messages! 

We love science experiments that are made up primarily of supplies that you likely already have in your home.

• Why do you think this will work?
• Which liquid do you think will make the best secret message?
• Why do people write secret messages?
• Juice (eg. Lemon)
• Lamp (or anything else that can be used as a heat source)
• In order to complete this experiment, you’ll need to gather all of your supplies along with a piece of paper, some q-tips, and a lamp or other item that you can use as a heat source.
• Next, you’ll mix your lemon juice with a slight amount of water. 
• Using your q-tip, use the mixture you’ve created to begin writing your message. 
• Allow it to dry. 
• Once dry, apply heat to it in order to get your message to appear.

Extend this project by attempting to write with a juice and water mixture, a milk and water mixture, or any other variation of the liquids we listed as necessary supplies!

8. Create Your Own Butterfly

Your little ones will love practicing their color mixing by creating their very own coffee filter butterflies. Hang them in the windows of your home to spread some cheer and to watch the sun flow through their beautiful wings! 

• What colors can mix together to make other colors?
• How do butterflies fly?
• What do you think will happen when we add water to the markers?
• Water spray bottle
• Allow your child to draw on the coffee filter to their heart’s content.
• Spray it with water and allow the colors to mix together.
• Allow it to dry thoroughly.
• Once dry, fold it like a fan and then clip it in the middle.

Ta-da, you’ve created a beautiful butterfly! 

9. Make A Duck Call

Give your family an excuse to head outdoors by allowing your children to craft their own duck calls. Test them out at a local pond and see if you can get the ducks to come closer to you for a healthy veggie snack! 

• Do you think ducks will be able to hear us with this?
• What other materials do you think could make this noise?
• How is what we have created similar to a duck’s beak?
• Plastic straw
• Push down on the straw to flatten one end and then cut the flattened end into a point.
• Flatten out your straw and then blow into it.
• Feel free to experiment with different amounts of flattening and different point shapes to see how you can adjust the sound.
• When finished, take your duck call into the wild to test it out.

10. Make Ivory Soap Boats

Did you ever carve items out of soap at camp when you were a child? Give your child the same opportunity. Soap can be carved using safe items, like plastic knives. 

• Why are we able to carve soap so easily?
• Do you think our boats float?
• Why do you think they float or sink?
• Carving tools (for kids)
• Allow your child to express their creative side by carving their boat out of soap. 
• Once they have finished carving it, allow them to test them out in the bathtub. . Extend their learning by discussing density with them–the soap floats because it is less dense than the water.

11. Make Your Own Quicksand 

As John Mullaney famously said, “I thought quicksand would be a much bigger problem in my adult life than it would have turned out.” For some reason, quicksand permeates children’s adventure stories – and their imaginations! 

• Where can we find quicksand in real life?
• How do you think quicksand works?
• What do you think we will need to make our own quicksand?
• Cornflower (one cup)
• Water (half cup)
• A container
• To make your quicksand, you’ll need to mix the cornflour and water. 
• Be sure to stir slowly in order to demonstrate – if you stir too quickly, it will become hard and you won’t be able to see it function the way it should!

12. Make Your Own Lava Lamp

We’ve tried this one in our classrooms, and trust us, our kids go wild year after year. Kids love making something that they can use as home decoration, and they love how easy it is to show new people – this is the experiment that lives on and on! 

• How do you think density is involved in this experiment?
• Why don’t the water and oil mix?
• Why can’t we shake our lava lamps?
• Clear Plastic Bottle
• Vegetable Oil
• Food Coloring
• Alka-Seltzer
• Pour water into the plastic bottle until it is approximately one quarter full. 
• Then pour vegetable oil in until the bottle is almost completely filled. 
• Allow some time for the oil and water to separate. 
• It is important that your children do not shake the bottle in this step. It will extend the experiment for no other reason than you waiting for the bubbles to dissipate. 
• Add as much food coloring as your child deems fit and then drop a piece of Alka-seltzer tablet into the bottle for the lava lamp fun to begin.

13. Guess the Smell

This one will take a little more prep work, but it’s a great touchstone for your children to begin discussing one of their five senses: the sense of smell! 

• What are examples of times we use our sense of smell?
• What other senses do we have?
• If you could only use one sense for the rest of your life, which one?
• Plastic Cups
• Smells (eg. coffee, cinnamon, vanilla, lemon juice)
• Place a variety of common smells in small plastic cups. We like to use coffee, cinnamon, vanilla, and lemon juice. 
• Pour these in and place tin foil securely over the top of the cup. 
• Poke small holes in the top of the foil. 
• Secure the foil with tape (on the sides, not over the holes). 
• Allow your children to guess the smells and record their findings on paper.

Home Science Experiments that take 1 to Several Hours

14. mangrove bioshield  .

Ecologists and conservationists are pushing for more regulations in building and saving mangrove forests around coastal areas. The reason is represented in this STEM activity. The trees act as a mangrove BioShield (bio = life, shield = protection), showing how natural obstacles can prevent critical damage from marine natural disasters such as tsunamis.

The mangrove BioShield can be for older elementary kids through to high school. Obviously, the younger they are, the more parent involvement. This experiment is done twice to show the effects of having and not having a BioShield. The first part uses little to no trees, and the second uses a forest of trees and rocks.

• What will happen in a tsunami if the village is without a BioShield? And the village with a BioShield?
• Would a BioShield help with hurricanes?
• Would you want to encourage people to save manatee forests if they are beneficial?
• Medium to large clear, plastic container
• Newspaper – wad into balls, then cover half of the bottom container – this help to keep the ground sturdy
• Mud – cover the newspaper and press it in to form a slope down to the empty side of the container. The top side should be flattened for the cardboard houses, then it slopes down into the empty half of the container.
• Cardboard houses (use the bottoms of milk cartons for the house and popsicle sticks for the roofs, place houses on the mud towards the top of the high slope
• Model trees or leafy stems from plants – Different amounts for activity 1 and activity 2
• Several small rocks
• Cardboard – long enough to fit across the container and tall enough to hold it from out of the water
• Water – enough to go halfway up the slope

A tsunami without the mangrove forest – insert only one or two trees down the slope. Place the cardboard piece into the water end of the container and move back and forth to create waves. Notice how easy it is for the water to destroy the village you’ve created.

Repeat the process of constructing the village, but this time insert a lot of trees down the slope to where the water meets the mud. They need to be deeply rooted like mangroves, and I’ve found that aquarium plants work well for this reason. Place the rocks within the mangrove forest and in front of the trees. Add a little bit more water. Insert the cardboard again and move it back and forth to create waves.  

15. A Greater Crater

When you look at the night sky and see the moon, one of the first things you notice is its craters. The moon is completely covered in them, and some are so large we can see them from Earth. Meteorites often make the craters that we see when they hit the surface, but it makes us wonder why some craters are so much bigger than others.

This experiment will help you to investigate one of the main reasons why craters come in different sizes.

• What causes craters?
• How big do the meteorites have to be to make a crater?
• What is it about the meteorite that causes the size of the crater?
• Paper to record your results
• Flat floor surface for the experiment, large enough for the newspaper to cover
• Shallow metal pan at least 2 inches deep
• Flour to fill 2 inches of the pan
• ¼ cup hot chocolate powder
• Mesh strainer or flour sifter
• Large marble (and others of varying sizes if comparing results)
• Metric ruler
• Tongs or long tweezers
• Pour the flour into the pan until it reaches 2 inches. Place the pan on top of the newspaper on a level surface.
• Sift a layer of hot chocolate powder over the flour (this is so you can better see the rays and other features of the craters).
• You will be dropping your marble from three different heights, then comparing the sizes of the craters. Measure the diameter (side to side) of the marble and record this on your paper as Marble 1. Hypothesize how large the crater will be and write that next to the diameter of Marble 1.
• Stand next to your pan and hold the marble at knee height above the flour. Drop the marble (do not throw it, just let it fall from your fingers) into the flour and study the shape of the crater. Look for a rim around the crater or any rays coming from the edges.
• Measure across the widest part of your crater, from rim to rim and record on your data sheet as Marble 1 – Knee Height – Width or something similar. You can also draw a picture of your results.
• Very gently use the tongs or long tweezers to remove the marble without destroying the crater.
• Repeat this procedure from waist height, shoulder height, top of head height. Make sure you aim in different parts of the flour so you don’t land on top of another crater. Record all of your results as the different heights you’re using.
• Compare your results.
• You can try again with a different sized marble as “Marble 2” to compare those results with each height as done with Marble 1.

Perhaps now, you’ll look at the moon a little differently!

16. Rube Goldberg Chain Reaction Machine

We’ve all seen them, some pretty far-out there chain reaction machines to complete simple tasks, usually in movies. But they are real , and are becoming even more popular now that we’re all stuck at home for a while. This is a fun way to explore physics with stuff you have at home.

Ask your child to decide what the end goal is (e.g. get the ball into the cup), and ask them to think about creative ways to make it get there. Working together, you can start with small pieces of a circuit to find out how your ball reacts to the set-up, and grow it from there. You can even refer to this video for more ideas:

• What will happen when the ball bounces off of this wall?
• How will these dominoes change the speed of the ball?
• What can we use to make sure that the ball goes in the direction we want it to at this point?
• What should we put here to get the best bounce? 
• Paper towel
• Toilet paper tubes
• Fixed objects like walls or furniture
• Any other toys and materials that can be used to build your circuit

To make this a true experiment, it needs to include more than a one-off demonstration, and there are a lot of ways to accomplish this.

• Set up parallel courses and use different sized or weighted balls to go through the circuit.
• Set up one elaborate circuit and use different objects one at a time.
• Set up circuits in different ways to see how different set-ups affect your end goal.

Another experimental component is the process used to create a circuit that reaches your end goal ( like this video about getting the ball into the cup, but you could come up with lots of other endpoints!). Along the way, you and your child get a lot of time to learn about momentum, velocity, friction, energy transfer, and interference (e.g., the cat). 

17. Melting

This is a simple and fun experiment that can be set up in a short time and then fill-up your day with observations and new experiments. Using only things you already have at home, you can set-up an engaging experiment with your kids!

Ice melts at different rates depending on a variety of factors including temperature, pressure, and if there are impurities (think salt, sugar, dirt) in the ice or touching the ice. There is a lot of opportunities to get creative and do the experiment in multiple ways, keeping your kids engaged and developing their investigative, experimental, and critical thinking skills.

• Which ice melts the fastest, slowest, and if they have any guesses about why?
• What other ice-melting experiments they think would be fun: Using different temperature liquids? Using different amounts of ice? Different sized cups?
• Lots of ice
• Several matching cups (i.e., they are the same size, shape, and color)
• Measuring cups
• A variety of liquids for the test
• Paper for writing down observations
• Measure the same amount of ice and place it in each cup.
• M easure equal amounts of each liquid and place them in the cups: try to complete this part quickly so that the ice in each cup is in liquid for as close the same amount of time as possible.
• Set up your cups in a place that is easy for your child to watch and observe.
• Ask them to check in at regular intervals (every 15 minutes, every hour) and record or talk to you about their observations.

Other potential experimental examples:

• Using different liquids to test if they affect melting time;
• Using the same liquid and placing ice in different locations to test what conditions throughout your home affect melting;
• Test if different amounts of ice melt at different rates;
• Test if different kinds of cups change melting time.

There are endless possibilities for you to come up with new ways to complete these simple experiments. You get the idea. Explore more!

18. Breathing Leaves

Science experiments don’t get much more simple than this one!  It’s effective though and kids will enjoy watching their leaf ‘breathe’. Learning about plant science is often tricky because it can seem a bit abstract. This experiment allows kids to see the process of plants making oxygen right before their eyes!

A question to ask beforehand:

• What do you think will happen if we leave it for a few hours?
• A fresh leaf from a tree
• A bowl of water
• Pluck a fresh leaf from a tree and place it in a bowl of water.
• Use a rock to weigh it down and leave the experiment out in the sun.
• Have your kids predict what they think they will see when they come back in a few hours (they can write their prediction down or draw a diagram if that’s more their style).
• After a few hours, your kids will see lots of tiny little bubbles on the edge of the leaf and in the glass bowl of water (use a magnifying glass to get a closer look if you have one).

So, what’s happening here? Leaves take in carbon dioxide and convert it to oxygen during photosynthesis. The bubbles you can see are the leaf releasing the oxygen it’s created. You could explain to your kids how trees and plants make the oxygen we need to breathe. Kids Fun Science explains this experiment in more detail and suggests taking it further by leaving the plant for a longer period of time (do you see more or fewer bubbles?) or placing a leaf in a dark area to see what difference that makes!

19. How Does Sunscreen Work?

If there’s one thing I know, it’s that kids hate wearing sunscreen! Trying to get it on them is like wrestling a crocodile. Maybe if they knew how sunscreen worked they’d understand how important it is to wear it when they’re out in the sun (and be slightly more cooperative when we’re lathering it over their little faces). This is a simple experiment that shows kids the difference wearing sunscreen will make to their skin.

• What do they observe when they come back?
• Why do they think one side faded and the other not?
• A piece of colored cardboard (a dark color would be best)
• Your usual bottle of sunscreen
• Have your kids smear the sunscreen over one part of the cardboard and leave the other part clear.
• Kids can then predict what they think will happen when they return to the experiment after a few hours.
• Talk to them about how the sun’s UV radiation is absorbed by the sunscreen so it can’t get through to damage the cardboard.

You could even take it further by trying different kinds of sunscreen or leaving your cardboard out during different times of the day.

20. Make A Rubber Egg

Imagine a world in which eggs can be used like bouncy balls. Well, with a couple of home supplies and a little bit of science, you can live in that world. Your child will be dazzled as they remove eggshells from eggs while leaving the insides intact. 

• Is vinegar an acid or a base?
• Is there another substance that could do this?
• Simply leave the egg in the vinegar for a few hours and wait to see what happens. Because of the transformative nature of this experiment, it lends itself to science journaling. 
• Consider having your kiddos draw before and after pictures of the eggs in order to track their journeys. 

21. Flying Tea Bags

Nothing will get your kids’ attention faster than telling them that you are going to spend some time creating something that will fly. However, because this experiment will involve fire, please ensure that you select a time in which you will be able to provide ample adult supervision. 

• How do we stay safe with fire?
• How do we make sure we don’t damage the surface we are working on?
• Why do you think the tea bag will fly?
• Single Serving Tea Bags
• A Small Bowl
• A Non-Flammable Work Surface
• First, open the tea bags and unfold them. 
• Empty the leaves from the bag. 
• Stand the tea bags up on your surface and light the top of each bag on fire. 

As they begin to burn, they will float into the sky! 

22. Make Wax Paper Lanterns

Your children will love the chance to display their fantastic art skills by creating these paper lanterns. If you want to add a culture lesson, have your children research German’s St. Martin’s Day and learn about why children parade through the streets with lanterns. We promise there’s a good moral story involved here! 

• When could we use lanterns?
• What safety considerations do we need to use in this project?
• Why can we see the light through the wax paper?
• Popsicle Sticks
• To begin, tear a ten-inch piece of wax paper off of the roll and cut it in half. 
• After that, fold each piece in half. 
• Allow your child to color their image on top of the wax paper. (This is a great place for an impromptu lesson in color mixing). 
• Fold the wax paper and iron it (consider something in between the crayon mess and the iron you use on your clothes). 
• Finally, glue the craft sticks into squares, add the wax paper, and turn it into a cube.

Voila, you’ve created your own lantern!

23. Create an Insect Habitat

Alright, this one isn’t for the faint of heart. Draw up your courage and send your child into the backyard to collect all of the creepy crawlies they’d like to.

Now you have a home for them. Better yet, you can keep your child entertained for hours as they track the growth of their bug friends.

• What do bugs need to survive?
• What do bugs eat?
• What is the difference between a need and a want?
• Imagination
• Find something that you’re willing to sacrifice to the bugs in order to create a habitat for them – we recommend a shadowbox so that your child can see inside, but a cardboard box will do just fine as well. 
• Ensure that there is breathing room for the bugs. 
• Create a habitat with sticks, bark, small rocks, dried leaves, and whatever else you can find.
• If you’re willing to hang onto the habitat long enough, use it as an opportunity to talk about decomposition as the bugs begin to break down the twigs.

Long-Term Science Experiments at Home

24. crystal kingdom.

This is the oldest trick in the book, but it’s popular because it’s so effective, fun, and has great results. The only drawback to most crystal-growing recipes is that they take ages to grow, and to be quite honest this one is no exception. In fact, these crystals will take several days to grow but the end result is worth it. The reason is that this experiment involves growing a whole landscape of beautifully colored salt and bluing crystals. Here’s a video for visual reference: 

A few things to keep in mind: Allow for plenty of air circulation, preferably inside rather than outside. Ammonia is not necessary but does help in the process.

• What will happen when you add ammonia?
• Why does more salt and less liquid create faster crystallization?
• What part does the bluing solution have in crystal growing?

(Answers can be found here )

• Two bottles of bluing solution
• Large tray/cookie sheets with sides
• Measuring cup
• Liquid watercolors
• Eye droppers
• Cut sponges into large pieces. Spread them out on the tray.
• Measure out 1 cup of each of salt, water, and bluing and then gently mix together.
• Evenly coat or sprinkle the mix over the sponges.
• Add 1 cup of ammonia to the sponges.
• Coat an extra 1 cup of salt on to the sponges.
• By now you’ll see some crystals growing . Sprinkle the magic mix again: 1 cup each of salt, water, and bluing. You can pour the ingredients onto the tray instead of on top of the crystals to keep them from breaking. Don’t worry, more will grow!
• Take an eyedropper, and drop a tablespoon of each liquid watercolor (undiluted) in different patterns over the sponges and crystals.
• Take note of your garden and what the crystal formations look like. You can make a sketch in your notebook as a before and after. Ask questions and observe!
• Observe how the crystals are bigger than before, and notice the colors aren’t as vibrant. Compare the differences in shapes, sizes, and colors.
• If you want more crystals to grow, add a little more water, bluing, and salt.

25. Blow up a Balloon with Yeast

We are surrounded by science in action, but sometimes it is really difficult to see what is happening, especially when it is on a small-scale. When we make bread, yeast ‘eats’ the sugars in the food and creates CO2, giving bread its airy texture. This experiment lets you both visualize what happens when yeast consumes sugar and is a great set-up for an experiment that can be observed throughout the day.

Depending on your supplies and time, you could start with a demonstration and use that to think of other tests, or you could set up several parallel tests at the same time.

• How quickly does the balloon filled with air?
• When does it stop filling (at some point the yeast will run out of food and will stop making gas)?
• Does the starting temperature affect the experiment?
• Does the balloon fill faster in different places in your home (try especially for different air-temperatures, you could include an outside location)?
• Some balloons
• Blow up the balloon a few times before starting so that it’s loosened up a bit.
• Fill the bottle with about 1 inch of warm water (heat is required to activate the yeast, but you could experiment with different temperatures), add the yeast and swirl to dissolve.
• Add the sugar and swirl more.
• Place the balloon over the opening to the bottle and wait. You should expect to see the balloon begin to inflate after around 20 minutes.
• Continue checking and observing how much the balloon inflates throughout the day.

More example experimental setups include:

• Do different temperatures – either with the water you start with or the air the yeast lives in – affect how quickly the balloon blows-up?
• Does using 2x the yeast result in a balloon that is 2x bigger, or blows-up 2x faster?
• Do different types of sugar (e.g., white sugar, honey, syrup, flour) affect how quickly the balloon blows up or how big it gets?

A sk your child to think of new experiments (you could prompt with some of the examples above, or ideas from this post ). 

26. Seed Germination

A really simple but fun multi-day experiment is germinating seeds under different conditions. This means finding some quick-sprouting seeds such as beans and putting them in different conditions to see how that affects germination (sprouting leaves and roots) and growth.

I love using seed experiments because they are inexpensive, simple, and leave a ton of room for creating your own unique experiment.

• Which seed will sprout fastest?
• Seeds (Beans, radishes, squashes, and many flowers sprout quickly from large seeds, making them good choices.)
• Small pots or paper cups
• Potting soil
• Cloth or paper towel
• Somewhere with good light
• To get started, you’ll need some seeds – feel free to choose something you already have, if you’re a gardener you might have some seeds ready for the coming season and could spare a few – or find something online or at your local nursery.
• Use small pots or paper cups and fill each with your growth material (we recommend a minimum of 3 for a useful comparison).
• Fill one with potting soil, one with sand, and one with a cloth or paper towel.
• Place them somewhere with good light, and add water.
• Ask your child to predict which seed will sprout fastest, and make observations every day. If possible, make them around the same time each day.
• Once you see growth, you can ask your child what they think caused any differences, and you can use that as a jumping-off point for more experiments

Additionally, you could:

• Use one type of seed and different types of growth media: soil, paper towel, gravel, sand, water, etc.
• You could use different seeds (beans, flowers, grass, herbs) and grow them under the same conditions (soil, water, sun exposure) to see how different plants grow differently.
• You could see how different light conditions (by a window, in the basement, in a bright room away from a window, etc.) affect germination.

You could also extend each experiment by simply continuing to grow each seed to learn whether the different germination time affects long-term growth (you may want to re-pot everything in the soil for this to be effective, depending on the specifics of your initial experiment).

27. Colored Celery

It’s hard to imagine plants having little capillaries inside them that transport water and nutrients, but this experiment shows that in action. It’s easy to set up, but you’ll have to wait at least a day to see some results. Your kids will be able to see how transpiration takes place and plants absorb water from the soil all the way up into their leaves.

• A few stalks of celery (celery works best for this because it’s a bit more visible, but you could also use flower stems)
• Different food coloring
• Place each stalk in a cup of colored water and make your predictions about what will happen.
• After a day or so you’ll see the celery leaves becoming the color of the water they’re standing in.
• Have your kids describe their observations (they can write down what they see or draw it if they prefer).
• If you look at the base of the stem you’ll also see tiny little holes that the colored water is traveling through.

When you’re done with the experiment, make sure you snap the celery and look inside – you should be able to see the capillaries in action. For more ideas, Little Bins for Little Hands has got some great hints and tips for this experiment.

28. Moldy Bread

This experiment is an oldie, but a goodie! Kids love looking at disgusting things and this one will certainly come up with the goods. Not only will kids learn about how mold grows, but they might also take on some lessons about the importance of washing their hands!

You might want to check out the results of this experiment at Science Alert before you start to see if your stomach is up to it.

• A few slices of bread
• Some ziplock bags
• Sticky little hands. 
• Get a few slices of bread and lay them out on your kitchen bench.
• Have your kids touch one piece of bread with dirty, unwashed hands.
• They can wash their hands with soap and water and touch another slice, then do the same using hand sanitizer.
• Leave one piece of bread untouched.
• Place them all in clear, labeled ziplock bags and predict which one will grow the most mold.
• Leave your bread slices for at least a week (it may take a bit longer, depending on the conditions where you live) and get the kids to record their observations.

You can also try wiping your bread slices on other surfaces to see what moldy results you get (their laptop or tablet is a great place to start)!

29. Sprouting Beans

Give your household a real survivalist feel by beginning an indoor garden. We recommend planting your beans in a clear cup so that your children can be privy to all of the processes during the plant’s journey.

• How does a plant grow?
• What does germination mean?
• What is in season to grow in our area now?
• Unprocessed Beans
• If you’d like your child to see every step of the process, consider placing the beans inside of a damp paper towel inside of a ziplock. 
• You can wait, see the germinated seed together, and then plant it inside of a small cup.
• Once inside the cup, watch it grow.

Extend your work by planting various beans and altering the growth conditions in order see what makes your beans grow best! 

30. Begin Composting

Begin your “go green” resolutions by teaching your child the value of composting! Best of all, once the science experiment is done, your family will have a recycling process that will last your entire lifetimes. 

• Why is composting important?
• How else can our household go green?
• Why do we need a foundation layer for compost?
• Compost Bin
• Organic Material
• First, create a compost bin. You can purchase one or build one out of wood. 
• To begin your composting, you’ll need even amounts of brown materials (think shredded paper, dryer lint, etc.) and green materials (think fruit and vegetable waste, lawn clippings, etc.). 
• If you’re really feeling fancy, throw some earthworms in there.

For days to come, your family will be able to discuss what can and cannot be broken down by the decomposers inside of the compost bin. Never-ending science! 

31. Turn Grapes Into Raisins

Your kids may or may not eat raising – but we can guarantee you, they’ve likely never considered the option of creating their own! 

• What other snacks can we make with science?
• Should we ever eat our experiments?
• How does this work?
• For this experiment, you’ll need grapes. (Really, that’s it!) 

Leave your grapes somewhere where they will not be disturbed and use this as an opportunity for your children to journal the changes in the grapes from day to day. Believe it or not, this type of sequential journaling is a valuable literacy skill! 

32. DIY Science Experiment

The best science experiment your child can engage in is the one they create themselves! Begin brainstorming a list of questions and let the world be their oyster as they plan and carry out their own experiments. Some of our favorite brainstorming questions, from Scholastic’s Science-Fair Project Guide, are listed below:

• What is the effect of toothpaste brand on teeth-cleaning power?
• What brand of trash bag can withstand the most weight before ripping?
• How does the type of material affect how long a shirt takes to dry?

Lately this has become a very common theme.

Kids are bored. They really want something to do. Something interesting, exciting and fun!

Parents are trying to find ways to entertain and educate their children.

Homeschooling has become incredibly popular, but parents are struggling to find cool science experiments to do at home. Something that is suitable without breaking the bank when it comes to supplies, won’t destroy their home, and that will actually teach their kids about chemistry, biology and physics.

So with that in mind, here are the top 20 Science Experiments to do at home as chosen by not only me, but the readers here at STEAM Powered Family!

The Best At Home Science Experiments

In selecting which experiments ranked as the absolute BEST science experiments to do with your kids at home we had a few different criteria.

• They needed to be popular! These experiments are tried and true, and have loyal following of readers that LOVE doing them. Once you try them, you will know why STEAM Powered Family readers voted these as their favourite science experiments!
• Supplies must be relatively easy to source. In most cases you will likely have all the materials you need at home right now. Where you need to order or purchase a few supplies, they are readily accessible and links to purchase are included.
• They must be easy to do, with logical, easy follow directions. We are all overwhelmed. No one wants an experiment that is complex and confusing.
• The experiments need to be adaptable to wide variety of ages, grades, abilities and interests.
• The lessons need to be interesting! In all of our science experiments and STEM activities, we include a scientific explanation that either your children can read themselves, or you can read and use to help explain the experiment.
• They need to be FUN!

With that in mind, here are our top 20 picks for the BEST science experiments to do at home with your kids!

Baking Soda and Vinegar Experiments

There are so many cool experiments you can do with these pantry staples. Yes, you can do a standard volcano, but you can also hatch dino eggs, create fireworks, set off explosive bottle rockets and more! You can keep your kids busy experimenting for a ages with all of our baking soda and vinegar ideas. Get your hands on some bulk vinegar and baking soda and get experimenting!

Oobleck is like slime, but much more fascinating and sciencey! Oobleck is a non-Newtonian Fluid that becomes solid under pressure, and liquifies when pressure is removed. It is fascinating, and we have a number of different recipes, so you can find the one that uses whatever you have available in the house.

Make a Compass

This science experiment is really cool and a wonderful tie into geography and social studies lessons. Kids learn how to make a compass with materials from around the house.

Make a Lava Lamp

With 5 different ways to make a Lava Lamp, it’s no wonder our readers rate this as one of their favourite activities! Kids are fascinated by the chemical reaction that causes the mesmerizing bubbles to bob up and down in a science driven lava lamp experiment.

Grow Crystals

This is one of the most beautiful experiments we have done and always gets rave reviews from readers. Growing crystals is a wonderful science experiment that has fantastic ties to studies in geology. You can also grow edible crystals. Plus the results… STUNNING!

Ready for a fun, giggle-fest science experiment? In this science experiment we are removing the shell of a raw egg! The result is a bouncy, colourful egg. This science experiment is the perfect compliment to a study of biology and reproduction as you can also use this experiment to teach the parts of the cell and egg.

Lemon Battery

You could make a battery with lemons, squash, pumpkins, potatoes, there are lots of options! But the lemons are by far the most popular battery project. You will need some supplies, but once you have those supplies you can reuse them in lots of circuit building activities. Plus, once you are finished making your lemon battery, you can make lemon volcanoes!

Wingardium Leviosar

Whether you are a fan of Harry Potter or not, this experiment with magnets is a hit with kids. It’s like magic as they make a feather levitate!

Walking Rainbow

This classic experiment is a beautiful demonstration of primary and secondary colours, while also learning about the fascinating science behind capillary action. All you need to start your rainbow walking is cups/jars, water, food colouring and paper towels!

Make Bioplastics

Making bioplastics is an experiment that is a HUGE hit with older kids as part of their studies in polymers and environmental sciences. We have made bioplastics with both milk and gelatin, so you can pick which one to tackle based on the supplies you have on hand. Wonderful for helping kids understand how we can make plastics, and the challenges of making plastics, without fossil fuels.

Build a Heart Model

This engineering project is a fantastic way to do some studies into biology and how the heart functions. Using recycled bottles, straws, a bit of playdough and water, you can have your model pumping in no time!

Skittles Experiment

A simple, yet timeless experiment. Kids of all ages love making these gorgeous images using nothing but candy, water and the magic of science. We also used this as a chance to explore van Gogh and fluid dynamics.

So easy, yet so amazing! Magic Milk is another classic experiment that is as simple or as complex as you want to make it. I did this with my middle school kids and we had a blast exploring how the fat content of our milk affected the explosion of colours!

Slurpee Science

Heat transfer is a fascinating science to explore with your kids. If you want to make this a more serious scientific study, you can focus on the effects of salt on ice, but we like to up the fun, so we turned it into a slurpee making science project. Kids love that delicious treat made with science!

Elephant Toothpaste

Elephant Toothpaste classic experiment creating a fantastic foamy fountain that can be done safely at home using easy to source supplies and has massive wow factor for students.

Make Water Rise

Another science experiment that is a little bit like magic! Kids will learn how to create a vacuum and make water magically rise into a container. So cool!

Balloon Races

Kids got ants in their pants? Need something that is educational and will help them burn energy? Balloon races are the answer! Kids will explore physics while having a blast running about and cheering on their balloon races!

Build a Water Clock or a Windmill

Both of these projects involve some engineering and of course science but they also have some fantastic book tie ins. I LOVE projects inspired by great books!

Build a Salt Circuit

Salt circuits are a great way to introduce kids to experiments with electricity and circuitry. The supplies are minimal, and it teaches kids excellent critical thinking and problem solving skills. Plus you can make it extra fun with a glow circuit option!

Build a Catapult

A favourite that captures the excitement of every generation, and was a MUST do in our top 20 science experiments is… building catapults! We work in a little extra physics and math by turning ours into games where we need to hit targets. A definite must do for all kids.

If you have flour, you can easily experiment with making your own sourdough starter.  Wild sourdough starters  tap into the abundant yeast in our homes and puts them to work making delicious bread. When it comes to science experiments you can do at home, few could be more delicious and rewarding than this one. You’ll also be helping scientists out along the way.

RELATED: BACK TO SCHOOL WITH CITIZEN SCIENCE

The Wild Sourdough Project is a global science experiment that hopes to discover how sourdough starter communities form over time. The team behind the effort is hoping to unravel how factors like geography and different kinds of flour affect the yeast communities. Best of all, the effort has a step-by-step guide that lets you learn how to make your own sourdough starter.

Create a Cloud in a Jar

Clouds are an important and often overlooked driver of Earth’s temperature. They trap sunlight in, but they also reflect it back into space. That role has climate scientists rushing to study our planet’s clouds, and how they’re changing.  NASA’s GLOBE Observer: Clouds  project taps citizen scientists to provide pictures of the sky, plus observations of cloud cover, type, sky conditions and visibility. That data helps info real science research and verify what satellites are seeing from space.

You can get involved with your kids and enrich the experience by adding lessons about clouds. For example, NASA has added a number of fun and easy ways to learn about climate science and clouds, including science experiments. One of the best related projects is to make a cloud in a jar. This simple science experiment is a powerful way to demonstrate how clouds work. You only need water, ice, a jar, and a few minutes of time.

Measure Rain and Snow with CoCoRaHS

Fall is approaching fast, which means many of us will soon be at home watching rain and snow out the window. Instead of succumbing to the gloom, why not make that weather into a fun science experiment for your kids?

The CoCoRaHS weather monitoring program, or Community Collaborative Rain, Hail, and Snow Network, is a network of volunteers who measure and report on precipitation. CoCoRaHS emphasizes training and education, and they even have an interactive website rich in educational resources and even National Weather Service lesson plans you can use at home.

RELATED: Getting Creative with Remote Science Learning

As a volunteer, you’ll use the same low-cost weather gauges that meteorologists and cities use. Then, when it rains, snows or hails, you’ll submit your precipitation data to the website where you can compare it to others in real-time. That information also helps out the National Weather Service, as well as researchers, farmers, emergency managers — and curious people everywhere.

Plant a Pollinator Garden

Pollinators play a vital role in Earth’s ecosystems, and yet they’re threatened by pesticides, disease, habitat loss and even climate change. That has many people searching for  ways to help save bees and other pollinators .

There are many options to chip in, but one of the most impactful things you and your kids can do at home is  plant a pollinator garden .

Not only will this serve to help struggling pollinators, it can also serve as a long-term science laboratory at home. SciStarter, the citizen-science group behind this blog post, has compiled an entire group of at-home science projects that can be done from your pollinator garden. You can watch moths, butterflies, bees, hummingbirds and more, then help scientists track their migration across the country.

Take Part: Plant a Pollinator Garden

Build a Bee Condo

If you already have a bumper garden at home, or it’s getting too cold to think about planting just yet, you can still stay indoors and help pollinators. The group behind National Pollinator Week has put together instructions for how you can build a home for native bees, called a bee condo. Unlike domesticated honey bees that live in apiaries, most native, wild bees you find in your backyard actually burrow their homes into the soil or a tree.

By building a bee condo, you can encourage bees to live nearby and also get a fun, DIY science experiment to do at home. Once it’s up, you can watch what kinds of critters take up residence there and report back on the results for science.

Scan the Night Sky

Around the world, light pollution from buildings and street lamps is blocking our view of the night sky. Most people who live in cities have never seen a truly dark sky, or the Milky Way. That’s not just bad for humans, it’s also bad for the plants, animals and insects who are disrupted by light pollution.

If you have a budding astronomy-lover in the house, you can participate in a science project called  Globe at Night  that aims to create a world-wide measure of light pollution in our night sky.

For this science experiment, you can start making observations using only a smartphone. You’ll mark the sky’s darkness by how many stars you can see. And you can get a sky quality meter through the project to help record even better data.

Take Part: Measure Light Pollution in Your Community

Measure Water Quality

More than 1.5 million volunteers from across the planet are already taking part in a science experiment to track — and protect — Earth’s waterways. The citizen science effort is called the  EarthEcho Water Challenge , and it has users buy a water test kit for about $25, then start collecting basic water data.

Volunteers record things like water clarity, temperature, pH and dissolved oxygen. That data gets plugged into a large database, where it’s used for real science research and to help protect waterways.

Take Part: Join the Earth Echo Water Challenge

Study the Vitamin C in Your Juice

Back in the golden age of sailing, sailors worried that they’d get scurvy. A lack of vitamin C during long voyages can cause a host of health problems. Scurvy leaves you weak, causes skin problems and gum disease, and makes it harder to heal. Scurvy can even kill you. This isn’t just an old-timey concern, either. Future space explorers will have to worry about vitamin C as they head off to explore the solar system. And that’s the angle utilized by a fun citizen science project called  Space Scurvy .

The project asks students to use household items to test the vitamin C content of juices from their schools and homes. The necessary tools for this science experiment should be easy to come by, and the site has fun and simple directions for you to follow.

15+ Science Experiments to Do at Home

This post may contain affiliate links.

Sharing is caring!

Kids seem to learn more about their environment through science experiments than they do by reading textbooks. Thankfully, there are a ton of science experiments to do at home .

Please don’t think I am totally anti-textbook. I certainly think there can be a time and a place for them.

This past year I used a public school high school science textbook for my daughter’s science curriculum. I wanted her to gain experience and practice using a standard textbook before she goes off to college in a few years. Knowing how to get information from a typical textbook is a skill that needs to be developed.

The textbook and accompanying workbook worked well, but the lab manual was a flop. I suppose it was written for teachers who have large science experiment cabinets and easy access to expensive equipment and chemicals.

That isn’t me . . . or any homeschool family I know!

I couldn’t rely on the suggested experiments in the book, so I found other experiments online.

These are all science experiments to do at home. They do not require any fancy equipment or hard-to-find materials. Most of the supplies are things you probably already have in your home, but some might require an Amazon order.

Science Experiments to Do at Home

Extract DNA from a Strawberry – DNA is in every living, but it isn’t often that we can see it with our own eyes. This fun science experiment to do at home uses simple items that you likely already own. If you don’t have any fresh strawberries, frozen works well too.

My family has done this experiment a few times with great results.

How Does a Leaf Breath – This science experiment lets you actually see photosynthesis take place. All you need is a leaf, clear bowl or cup, and water.

Grow a Germ Farm – Find out how much bacteria is really all around you with this germ experiment.

My family did this science experiment at home a few years ago and my kids still talk about it. They loved being able to check on the growth each day and they felt like ‘real scientists’ with their petri dishes.

Gummy Bear Osmosis – My kids are always more interested in schoolwork if the lessons include food. This is an easy and fun science experiment to do at home because it uses easy-to-find materials – gummy bears and water.

Make Oobleck – Study non-newtonian fluids with this hands-on experiment for kids. This in-depth article explains how to do this science experiment at home, but also why it works.

Sharpie Solubility – Explore the concept of solubility with sharpies. Kids use the permanent markers to draw simple lines on coffee filters and place them in three common substances. It doesn’t take long to see which substance helps break down the ink.

Elephant Toothpaste – This experiment creates a big foamy mess . . . something kids always seem to enjoy! Messes are worth it if they lead to learning though. Kids can learn all about exothermic reactions with this cool experiment.

How to Clean Pennies – Do your kids ever want to just play with random condiments? My kids loved to do this when they were little. Sometimes they were pretending to be chefs and sometimes they were pretending to be scientists.

Let your little scientists experiment with a few kitchen staples (lime/lemon juice, soy sauce, ketchup, vinegar, and salt) and see if they can remove the patina from dirty pennies.

Test PH Level – This science experiment to do at home is really simple but seems impressive. Use red (purple) cabbage to create an indicator solution. Then kids can test just about anything to determine the ph level and whether something is an acid or a base.

Make Ice Cream in a Bag – Kids can observe changing states of matter while they make dessert. This is a win-win!

Create Hot Ice Crystals – This experiment will blow your kids minds! It only uses two common household supplies, but produces a crystal ‘ice’ tower that is hot to the touch.

• 1 1/2 – 2 tablespoons of contact saline solution (or slime activator)
• 1 tablespoon of baking soda
• (Optional) Food coloring
• Mix the Glue: Squeeze the bottle of glue into a bowl. Add food coloring if you’d like, and mix it in. Then, stir in the baking soda.
• Activate the Slime: Add 1 1/2 tablespoons of saline solution and stir. If it’s too sticky, add more saline solution, a little at a time. The more you add, the thicker it will be. The less you add, the slimier it will be.
• Knead the Slime: Use your hands to knead the slime until it holds together. It will be wet and gooey at first, but just keep kneading until it all comes together.
• 12-inch balloon
• Empty 2-liter plastic bottle
• Baking soda
• White distilled vinegar
• Teaspoon or small measuring cup
• Prepare the Balloon and Bottle: Use a funnel to fill the balloon halfway with baking soda. Pour vinegar into the bottle, filling it about one-third full.
• Attach the Balloon: Carefully stretch the balloon over the neck of the bottle without letting the baking soda fall in.
• Trigger the Reaction: Lift the balloon so that the baking soda falls into the vinegar. The mixture will fizz and bubble, and the balloon will inflate.
• Observe: Watch the reaction and record your observations. Try using more or less baking soda and vinegar and see how it impacts the balloon’s size.
• Two glass bowls (or just one if needed)
• Food coloring
• Cold Water: Fill one bowl with cold water and add a few drops of food coloring. Time how long it takes for the color to spread.
• Hot Water: In a second bowl, add hot water and food coloring at the same time as the cold bowl. Time how long it takes the color to spread.
• Observe: Notice the difference in how quickly the colors spread. You can also try using a thermometer to measure and compare temperatures.
