Every time you read about doing an experiment or starting a science fair project, it always says you need a hypothesis. How do you write a hypothesis? What is it? How do you come up with a good hypothesis?
of Your Favorite Company!
What is a hypothesis?
No. A hypothesis is sometimes described as an educated guess. That's not the same thing as a guess and not really a good description of a hypothesis either. Let's try working through an example.
If you put an ice cube on a plate and place it on the table, what will happen? A very young child might guess that it will still be there in a couple of hours. Most people would agree with the hypothesis that:
An ice cube will melt in less than 30 minutes.
You could put sit and watch the ice cube melt and think you've proved a hypothesis. But you will have missed some important steps.
For a good science fair project you need to do quite a bit of research before any experimenting. Start by finding some information about how and why water melts. You could read a book, do a bit of Google searching, or even ask an expert. For our example, you could learn about how temperature and air pressure can change the state of water. Don't forget that elevation above sea level changes air pressure too.
Now, using all your research, try to restate that hypothesis.
An ice cube will melt in less than 30 minutes in a room at sea level with a temperature of 20C or 68F.
But wait a minute. What is the ice made from? What if the ice cube was made from salt water, or you sprinkled salt on a regular ice cube? Time for some more research. Would adding salt make a difference? Turns out it does. Would other chemicals change the melting time?
Using this new information, let's try that hypothesis again.
An ice cube made with tap water will melt in less than 30 minutes in a room at sea level with a temperature of 20C or 68F.
Does that seem like an educated guess? No, it sounds like you are stating the obvious.
At this point, it is obvious only because of your research. You haven't actually done the experiment. Now it's time to run the experiment to support the hypothesis.
A hypothesis isn't an educated guess. It is a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.
Once you do the experiment and find out if it supports the hypothesis, it becomes part of scientific theory.

Steps in a Science Fair Project
What are the steps in a science fair project.
Pick a topic
Construct an exhibit for results
Write a report
Practice presenting
Some science fair projects are experiments to test a hypothesis . Other science fair projects attempt to answer a question or demonstrate how nature works or even invent a technology to measure something.
Before you start, find out which of these are acceptable kinds of science fair projects at your school. You can learn something and have fun using any of these approaches.
First, pick a topic. Pick something you are interested in, something you'd like to think about and know more about.
Then do some background research on the topic.
Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something, take and record measurements, and report.
Design and carry out your research, keeping careful records of everything you do or see and your results or observations.
Construct an exhibit or display to show and explain to others what you hoped to test (if you had a hypothesis) or what question you wanted to answer, what you did, what your data showed, and your conclusions.
Write a short report that also states the same things as the exhibit or display, and also gives the sources of your initial background research.
Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

The Ultimate Science Fair Project Guide – From Start to Finish
When our daughter entered her first science fair, we kept seeing references to the Internet Public Library Science Fair Project Resource Guide . However, the IPL2 permanently closed… taking the guide with it. Bummer ! After now participating in over a half-dozen elementary school science fairs (including a first-place finish!), we created our own guide to help other students go from start to finish in their next science fair project. If this is your first science fair, have fun! If you’ve done it before, we hope this is your best one! Let’s science!

Other Resources for the Fair. Along the way, you will likely encounter challenges or get stuck. Don’t give up – it’s all part of the scientific process. Check out our STEMium Resources page for more links and resources from the web. We also have additional experiments like the germiest spot in school , or the alka-seltzer rocket project that our own kids used.
Getting Started – Why Do a Science Fair Project
For many students, participating in the science fair might be a choice that was made FOR you. In other words, something you must do as part of a class. Maybe your parents are making you do it. For others, maybe it sounded like a cool idea. Something fun to try. Whatever your motivation, there are a lot of great reasons to do a science fair project.
Challenge yourself
Learn more about science
Explore cool technology
Make something to help the world! (seriously!)
Win prizes (and sometimes even money)
Do something you can be proud of!
Many students will participate in a science fair at their school. But there are also national competitions that include 1000s of participants. There are also engineering fairs, maker events, and hackathons. It’s an exciting time to be a scientist!! The list below gives examples of national events.

What’s the Scientific Method?
Before we jump into your project, it’s important to introduce a key concept: The Scientific Method . The scientific method is the framework scientists use to answer their questions and test their hypothesis. The figure below illustrates the steps you’ll take to get to the end, but it starts with asking a question (you’ve already finished the first step!).
After we find a problem/idea to tackle, and dig into some background research, we create a guess on a potential solution. This is known as our hypothesis.
Example of a Hypothesis
My brother can hold his breath underwater longer than I can (“our problem”) –> how can I hold my breath longer? (“our question”) –> if I drink soda with caffeine before I hold my breath, I will be able to stay underwater longer (“our solution”). Our hypothesis is that using caffeine before we go underwater will increase the time we hold our breath. We’re not sure if that is a correct solution or not at this stage – just taking a guess.
Once we have a hypothesis, we design an experiment to TEST our hypothesis. First, we will change variables/conditions one at a time while keeping everything else the same, so we can compare the outcomes.
Experimental Design Example
Using our underwater example, maybe we will test different drinks and count how long I can hold my breath. Maybe we can also see if someone else can serve as a “control” – someone who holds their breath but does not drink caffeine. For the underwater experiment, we can time in seconds how long I hold my breath before I have a drink and then time it again after I have my caffeine drink. I can also time how long I stay underwater when I have a drink without caffeine.
Then, once we finish with our experiment, we analyze our data and develop a conclusion.
How many seconds did I stay underwater in the different situations?
Which outcome is greater? Did caffeine help me hold my breath longer?
Finally, (and most important), we present our findings. Imagine putting together a poster board with a chart showing the number of seconds I stayed underwater in the different conditions.
Hopefully you have a better sense of the scientific method. If you are completing a science fair project, sticking with these steps is super important. Just in case there is any lingering confusion, here are some resources for learning more about the scientific method:

What Science Fair Project Should I Do?
And science is no different.
Just know that if you can get through the idea part, the rest of the science fair is relatively smooth sailing. Remember to keep an open mind and a positive outlook . Each year 100s of 1000s of kids, teenagers and college students come up with new projects and ideas to test. You’ve got this!
What Makes a Great Science Fair Project? Start with a Problem To Solve
As we discuss below, good science experiments attempt to answer a QUESTION. Why is the sky blue? Why does my dog bark at her reflection? First, we will step through some ways to find TESTABLE QUESTIONS. These questions that you create will be what you work on for your science fair project. Pick something fun, something interesting and something that you are excited about. Not sure what that looks like? Step through some of the tips below for help.
Use the Google Science Fair Idea Generator
Are you surprised Google made a tool for science fair projects?? Our post called the low-stress way to find a science fair project gives a more in-depth overview about how to use it. It’s a great first stop if you’re early in the brainstorming process.
Answer your own questions
What type of music makes you run faster?
Can boys hold their breath underwater longer than girls?
How can I be sure the sandwich I bought is gluten free?
If we plant 100 trees in our neighborhood, will the air be cleaner?
Still stuck? Get inspiration from other science fair projects
Check out the Getting Started section and look at some of the winning science project ideas, our STEMium experiments and our Resource page. We’ve presented a ton of potential idea starters for you – take time to run through some of these, but our suggestion is to give yourself a deadline to pick an idea . Going through the lists could take you longer than you think, and in many cases sometimes it’s just better to pick something and go for it! The next section will take you through how to create testable questions for your project.
Starting Your Project: Find A Testable Question
The best experiments start with a question. Taking that a step further, the questions you useyou’re your science fair project should be ones that are TESTABLE. That means something you can measure. Let’s look at an example. Let’s say I’m super excited about baking. OH YEA!! I love baking. Specifically, baking cakes. In fact, I love baking cakes so much that I want to do a science project related to cakes. We’ve got two questions on cakes that we created. Which question below could be most useful for a science fair project:
1) Can eating cake before a test improve your score?
2) Why isn’t carrot cake more popular than chocolate cake?
The second question isn’t necessarily a bad question to pick. You could survey people and perhaps tackle the question that way. However, chances are you will get a lot of different answers and it will probably take a lot of surveys to start to pick up a trend.
Although, the first question might be a little easier. How would you test this? Maybe you pick one type of cake and one test that you give people. If you can get five people to take the test after eating cake and five people take the test with no cake, you can compare the test results. There might be other variables beyond cake that you could test (example: age, sex, education). But you can see that the first question is probably a little easier to test. The first question is also a little easier to come up with a hypothesis.
At this point, you’ve got an idea. That was the hard part! Now it’s time to think a little more about that idea and focus it into a scientific question that is testable and that you can create a hypothesis around .
What makes a question “testable”?
Testable questions are ones that can be measured and should focus on what you will change. In our first cake question, we would be changing whether or not people eat cake before a test. If we are giving them all the same test and in the same conditions, you could compare how they do on the test with and without cake. As you are creating your testable question, think about what you WILL CHANGE (cake) and what you are expecting to be different (test scores). Cause and effect. Check out this reference on testable questions for more details.
Outline Your Science Project – What Steps Should I Take?
Do Background Research / Create Hypothesis
Science experiments typically start with a question (example: Which cleaning solution eliminates more germs?). The questions might come up because of a problem. For example, maybe you’re an engineer and you are trying to design a new line of cars that can drive at least 50 mph faster. Your problem is that the car isn’t fast enough. After looking at what other people have tried to do to get the car to go faster, and thinking about what you can change, you try to find a solution or an answer. When we talk about the scientific method, the proposed answer is referred to as the HYPOTHESIS.

The information you gather to answer these research questions can be used in your report or in your board. This will go in the BACKGROUND section. For resources that you find useful, make sure you note the web address where you found it, and save in a Google Doc for later.
Additional Research Tips
For your own science fair project, there will likely be rules that will already be set by the judges/teachers/school. Make sure you get familiar with the rules FOR YOUR FAIR and what needs to be completed to participate . Typically, you will have to do some research into your project, you’ll complete experiments, analyze data, make conclusions and then present the work in a written report and on a poster board. Make a checklist of all these “to do” items. Key things to address:
Question being answered – this is your testable question
Hypothesis – what did you come up with and why
Experimental design – how are you going to test your hypothesis
Conclusions – why did you reach these and what are some alternative explanations
What would you do next? Answering a testable question usually leads to asking more questions and judges will be interested in how you think about next steps.

Way to go! You’ve found a problem and identified a testable question. You’ve done background research and even created a hypothesis. It’s time to put it all together now and start designing your experiment. Two experiments we have outlined in detail – germiest spot in school and alka-seltzer rockets – help show how to set up experiments to test variable changes.
The folks at ThoughtCo have a great overview on the different types of variables – independent, dependent and controls. You need to identify which ones are relevant to your own experiment and then test to see how changes in the independent variable impacts the dependent variable . Sounds hard? Nope. Let’s look at an example. Let’s say our hypothesis is that cold weather will let you flip a coin with more heads than tails. The independent variable is the temperature. The dependent variable is the number of heads or tails that show up. Our experiment could involve flipping a coin fifty times in different temperatures (outside, in a sauna, in room temperature) and seeing how many heads/tails we get.
One other important point – write down all the steps you take and the materials you use!! This will be in your final report and project board. Example – for our coin flipping experiment, we will have a coin (or more than one), a thermometer to keep track of the temperature in our environment. Take pictures of the flipping too!
Analyze Results – Make Conclusions
Analyzing means adding up our results and putting them into pretty pictures. Use charts and graphs whenever you can. In our last coin flipping example, you’d want to include bar charts of the number of heads and tails at different temperatures. If you’re doing some other type of experiment, take pictures during the different steps to document everything.
This is the fun part…. Now we get to see if we answered our question! Did the weather affect the coin flipping? Did eating cake help us do better on our test?? So exciting! Look through what the data tells you and try to answer your question. Your hypothesis may / may not be correct. It’s not important either way – the most important part is what you learned and the process. Check out these references for more help:

How to make a chart in Excel
Presentation Time – Set Up Your Board, Practice Your Talk
Personally, the presentation is my favorite part! First, you get to show off all your hard work and look back at everything you did! Additionally, science fair rules should outline the specific sections that need to be in the report, and in the poster board – so, be like Emmett from Lego Movie and read the instructions. Here’s a loose overview of what you should include:
Title – what is it called.
Introduction / background – here’s why you’re doing it and helping the judges learn a bit about your project.
Materials/Methods – what you used and the steps in your experiment. This is so someone else could repeat your experiment.
Results – what was the outcome? How many heads/tails? Include pictures and graphs.
Conclusions – was your hypothesis correct? What else would you like to investigate now? What went right and what went wrong?
References – if you did research, where did you get your information from? What are your sources?
The written report will be very similar to the final presentation board. The board that you’ll prepare is usually a three-panel board set up like the picture shown below.
To prepare for the presentation, you and your partner should be able to talk about the following:
why you did the experiment
the hypothesis that was tested
the data results
the conclusions.
It’s totally OK to not know an answer. Just remember this is the fun part!
And that’s it! YOU DID IT!!
Science fair projects have been great opportunities for our kids to not only learn more about science, but to also be challenged and push themselves. Independent projects like these are usually a great learning opportunity. Has your child completed a science fair project that they are proud of?

Hypothesis Examples
A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method . A good hypothesis is testable, meaning it makes a prediction you can check with observation or experimentation. Here are different hypothesis examples.
Null Hypothesis Examples
The null hypothesis (H 0 ) is also known as the zero-difference or no-difference hypothesis. It predicts that changing one variable ( independent variable ) will have no effect on the variable being measured ( dependent variable ). Here are null hypothesis examples:
Plant growth is unaffected by temperature.
If you increase temperature, then solubility of salt will increase.
Incidence of skin cancer is unrelated to ultraviolet light exposure.
All brands of light bulb last equally long.
Cats have no preference for the color of cat food.
All daisies have the same number of petals.
Sometimes the null hypothesis shows there is a suspected correlation between two variables. For example, if you think plant growth is affected by temperature, you state the null hypothesis: “Plant growth is not affected by temperature.” Why do you do this, rather than say “If you change temperature, plant growth will be affected”? The answer is because it’s easier applying a statistical test that shows, with a high level of confidence, a null hypothesis is correct or incorrect.
Research Hypothesis Examples
A research hypothesis (H 1 ) is a type of hypothesis used to design an experiment. This type of hypothesis is often written as an if-then statement because it’s easy identifying the independent and dependent variables and seeing how one affects the other. If-then statements explore cause and effect. In other cases, the hypothesis shows a correlation between two variables. Here are some research hypothesis examples:
If you leave the lights on, then it takes longer for people to fall asleep.
If you refrigerate apples, they last longer before going bad.
If you keep the curtains closed, then you need less electricity to heat or cool the house (the electric bill is lower).
If you leave a bucket of water uncovered, then it evaporates more quickly.
Goldfish lose their color if they are not exposed to light.
Workers who take vacations are more productive than those who never take time off.
Is It Okay to Disprove a Hypothesis?
Yes! You may even choose to write your hypothesis in such a way that it can be disproved because it’s easier to prove a statement is wrong than to prove it is right. In other cases, if your prediction is incorrect, that doesn’t mean the science is bad. Revising a hypothesis is common. It demonstrates you learned something you did not know before you conducted the experiment.

Science projects are not just about fun experiments; they also involve forming hypotheses to make educated guesses about outcomes. But what makes a good hypothesis for a science project? In this blog, we’ll explore the key components of a successful hypothesis.
Selecting the right 5th-grade science project can be a challenge, and we’ll share some valuable tips to help you choose the perfect one. We’ll dive into the importance of combining hypothesis with your science project and why it’s a vital aspect of learning and discovery.
But that’s not all! We’ve also compiled an extensive list of 120+ exciting 5th-grade science project ideas with hypothesis, providing you with a wealth of inspiration for your next scientific adventure. Stay tuned with us to unleash the world of 5th-grade science project ideas with hypothesis and nurture your curiosity in the process.
What Is A Good Hypothesis For A Science Project?
Table of Contents
A good hypothesis for a science project is like a smart guess. It helps scientists figure out what they think will happen in their experiment. To make a good hypothesis, you need to use words like if and then. For example, If I water the plant every day, then it will grow taller. This shows what you’re going to do and what you expect to see.
In addition, a strong hypothesis also needs to be testable. That means you can experiment to see if it’s true or not. It’s like a detective’s clue that leads you to find the answer. Scientists use good hypotheses to guide their experiments and learn new things about the world. So, making a good hypothesis is an important part of any science project.
Things To Remember While Selecting A 5th Grade Science Project Ideas With Hypothesis
Here are some things to remember while selecting a 5th grade science project ideas with hypothesis:
1. Personal Interest
Choose a 5th-grade science project that interests you. Picking a topic you’re curious about makes the project more enjoyable. Whether it’s plants, animals, or space, your passion can make learning fun.
2. Age-Appropriate
Make sure the project is right for your grade level. A 5th-grade project shouldn’t be too simple or too complex. It should match your skills and what you’ve learned in school.
3. Available Resources
Check if you have access to the materials you need. Some projects might need special tools or expensive stuff. It’s essential to choose something you can do with the materials you have.
4. Safety First
Keep safety in mind. Select a project that’s safe to do at home or in school. Make sure you won’t be using anything harmful or dangerous.
5. Clear Instructions
Look for a project with clear instructions. It’s easier when you know what to do step by step. Projects with easy-to-follow directions help you succeed and learn better.
Developing A Hypothesis For Your Science Project
Developing a hypothesis for your science project is a crucial step. It’s like making an educated guess about what you think will happen during your experiment. Here are seven key points to consider while creating a hypothesis:
Identify the Variables: Determine the two things you’re testing in your experiment, the if and then parts. For example, if you’re testing plant growth, the variables could be amount of sunlight and plant height.
Be Specific: Make sure your hypothesis is clear and precise. Avoid vague or broad statements. The more specific, the better.
Predict the Outcome: Your hypothesis should state what you expect to happen. Will one variable cause a change in the other? State your prediction clearly.
Use If-Then Statements : Craft your hypothesis using if-then statements to show the relationship between the variables. For instance, If the amount of sunlight increases, then the plant height will also increase.
Keep It Testable: Ensure that your hypothesis is something you can test through an experiment. It should lead to concrete results that you can measure.
Avoid Bias: Make sure your hypothesis doesn’t show your personal beliefs. It should be based on research and evidence, not what you want to happen.
Revisit and Revise : As you conduct your experiment, be ready to adjust your hypothesis if the results don’t match your initial prediction. Science is all about learning and adapting.

A hypothesis is an educated guess about what you think will happen in a scientific experiment, based on your observations. Before conducting the experiment, you propose a hypothesis so that you can determine if your prediction is supported.
There are several ways you can state a hypothesis, but the best hypotheses are ones you can test and easily refute. Why would you want to disprove or discard your own hypothesis? Well, it is the easiest way to demonstrate that two factors are related. Here are some good scientific hypothesis examples:
Hypothesis: All forks have three tines. This would be disproven if you find any fork with a different number of tines.
Hypothesis: There is no relationship between smoking and lung cancer. While it is difficult to establish cause and effect in health issues, you can apply statistics to data to discredit or support this hypothesis.
Hypothesis: Plants require liquid water to survive. This would be disproven if you find a plant that doesn't need it.
Hypothesis: Cats do not show a paw preference (equivalent to being right- or left-handed). You could gather data around the number of times cats bat at a toy with either paw and analyze the data to determine whether cats, on the whole, favor one paw over the other. Be careful here, because individual cats, like people, might (or might not) express a preference. A large sample size would be helpful.
Hypothesis: If plants are watered with a 10% detergent solution, their growth will be negatively affected. Some people prefer to state a hypothesis in an "If, then" format. An alternate hypothesis might be: Plant growth will be unaffected by water with a 10% detergent solution.

How to Write Up an Elementary Volcano Science Project
Jennifer tolbert, 27 jun 2018.
The baking soda and vinegar volcano is a favorite science experiment among elementary students. It is important to make your presentation stand out from the other students at the science fair with an exceptional presentation. Also be sure to follow the teacher's guidelines or science fair guidelines to ensure that your score is as high as possible.
Write an introduction. The introduction is your first impression. Be sure it is concise and accurately introduces exactly what you studied in the experiment. This is also an excellent place to include fun facts, background information or general volcano information. The reaction is due to the properties of bases and acids and would be important to include in your experiment. Identify the variable that you are testing, such as the ratio to vinegar and baking soda. Or maybe you would like to see what other base-acid combinations would produce similar eruptions.
Write a hypothesis. Remember a hypothesis is an educated guess or prediction. Explain what you believe will happen during the experiment based upon your previous knowledge or research. The hypothesis should be written in a declarative sentence.
List your materials. Provide a detailed list of all of the materials you used when you conducted the experiment. Be sure to also include how much of each material was used. Explain whether you made your own volcano or bought a kit.
Write your procedure. The procedure should be written step-by-step, in detail. If someone else could easily reproduce your experiment, you have probably written a fairly clear procedure. Be detailed, accurate and logical in your explanation. Procedures are usually written in a numerical list format.
Explain your results. Be sure your results reflect exactly what you were testing. You can provide observations or measurements. If applicable, you can create a chart or graph to describe any numerical data you may have taken. You may want to describe what the eruptions looked like, how long they lasted or how explosive the reactions were.
Write a conclusion. Basically, sum up what you learned during the experiment. Say whether or not your hypothesis was correct. Point out patterns in your data and explain if they were consistent with your previous knowledge of the subject. Also, do not forget to relate how that information can be used in the real world. This would also be a good spot to place recommendations if there are changes you would make to the experiment.

Science Projects on Hypothesis for Volcanoes
How to Add a Variable to a Volcano Science Project
Volcanoes have captured the imaginations of science-fair participants for generations. The fun of simulating oozing lava and creating volcanic-like explosions is undeniable. Volcanoes play an important role in the topographical and meteorological patterns of Earth’s past, present and future. The complex science of volcanoes lends itself to a variety of science-project hypotheses.
Amateur Volcanologist
Volcanologists study both active and dormant volcanoes, how they formed, and their current and historic activity. According to the University of Oregon, most of the work of the volcanologist happens in the laboratory, not at the edge of a red-hot volcano writhing with molten lava. In fact, investigating data and coming up with hypotheses is one of the most important jobs of a volcanologist.
Hazardous Volcanoes
Volcanic eruptions have many hazards, from lava flows to spewing ash. Determining where the most hazardous volcanoes are located in the world is a good project hypothesis. First, students would need to determine the main hazards of a volcano and consider factors such as human life, plant and animal life, air quality and damage to property. Data would need to be collected on volcanoes in different parts of the world and students would need to form conclusions based on the same criteria for each volcano.
Effects on Earth System
Throughout history, volcanoes have had a profound effect on Earth’s systems. Volcanoes have changed the topography of the world and even destroyed civilizations. The effects on Earth’s systems by volcanoes that are currently active are more subtle, but they can still have an impact. Choosing an active volcano and hypothesizing about its impact on the environment around it would make an interesting project. Students can consider the impact to air quality, plant life and even the weather.
Chemistry and Volcanoes
A visually pleasing volcano project involves simulating an eruption. The intensity of volcanic eruptions varies widely and students can hypothesize which type of chemical reactions could cause the biggest eruptions. For example, a project could hypothesize that yeast combined with hydrogen peroxide would create a bigger explosion than vinegar combined with baking soda. Students, with adult supervision, can mix different components to demonstrate the power of volcanic eruptions.
