3-step diagramming

How to Draw a Science Diagram

Why draw science diagrams.

While teaching science, there are several elements, objects, processes, or outputs/results that cannot be seen through naked eyes or felt merely by touching the substances. Some experiments require expensive equipment and materials, and many schools can’ t afford that.

This is where science diagrams come into the picture. With the help of diagrams, science teachers can easily illustrate the equipment, substances, and objects. In addition to this, the trainers also use directional arrows to represent the flow of processes that occur/take place before getting the final results.

For instance, chemistry professors cannot show molecules or atoms of certain substances to students. Likewise, these diagrams can help physics professors explain the magnetic fields of an electromagnet.

Another good example could be in the biology subject where the professors cannot dissect a human body to explain how it works. This is done with the help of diagrams where they draw all the arteries and veins to explain how they’re responsible for the blood circulation in a body.

Ways of Making Science Diagrams

Traditionally, students draw science diagrams manually on paper using a pencil, a couple of colored markers, a scale (ruler), and an eraser (to make minor adjustments and corrections), whereas lecturers do that on a blackboard or whiteboard using chalks or markers respectively.

Drawbacks of Traditional Method

Although the above method doesn’t require scholars and professors to carry any advanced equipment, the entire process is extremely time consuming and is prone to errors. This method also demands that the person holding a pencil, chalk, or marker has decent drawing skills failing to which, the diagram may not illustrate the object or process correctly upon completion.

Thankfully, it’s an IT era where things have become way easier with the help of software applications, and drawing science diagrams is not any exception either.

Today, there are several free and paid online diagramming tools that help you draw science diagrams quickly and easily as compared to the traditional method, without having you to be proficient in fine arts.

Such online tools have a complete library dedicated to a particular subject where all the required icons and symbols are present and can be used as needed. These programs also have lines and arrows called ‘Connectors’ to illustrate the relationship and workflow between the two elements. As a trainer or student, all you need to do is, drag and place the relevant symbols in the work area, and use the connectors to illustrate the relations or processes.

How to Make Science Diagrams Online?

The easiest way to draw science diagrams is with an efficient online tool. An example of one such diagramming solution is EdrawMax Online that is not only free to use, it also lets you export your creations to your preferred file format.

How to Conduct a Science Experiment

Experimentation is the method by which scientists test natural phenomena in the hopes of gaining new knowledge.. Good experiments follow a logical design to isolate and test specific, precisely-defined variables. By learning the fundamental principles behind experimental design, you'll be able to apply these principles to your own experiments. Regardless of their scope, all good experiments operate according to the logical, deductive principles of the scientific method, from fifth-grade potato clock science fair projects to cutting-edge Higgs Boson research. [1] X Research source

Designing a Scientifically Sound Experiment

• For instance, if you want to do an experiment on agricultural fertilizer, don't seek to answer the question, "Which kind of fertilizer is best for growing plants?" There are many different types of fertilizer and many different kinds of plants in the world - one experiment won't be able to draw universal conclusions about either. A much better question to design an experiment around would be "What concentration of nitrogen in fertilizer produces the largest corn crops?"
• Modern scientific knowledge is very, very vast. If you intend to do serious scientific research, research your topic extensively before you even begin to plan your experiment. Have past experiments answered the question you want your experiment to study? If so, is there a way to adjust your topic so that it addresses questions left unanswered by existing research?

• For instance, in our fertilizer experiment example, our scientist would grow multiple corn crops in soil supplemented with fertilizers whose nitrogen concentration differs. He would give each corn crop the exact same amount of fertilizer. He would make sure the chemical composition of his fertilizers used did not differ in some way besides its nitrogen concentration - for instance, he would not use a fertilizer with a higher concentration of magnesium for one of his corn crops. He would also grow the exact same number and species of corn crops at the same time and in the same type of soil in each replication of his experiment.

• Typically, a hypothesis is expressed as a quantitative declarative sentence. A hypothesis also takes into account the ways that the experimental parameters will be measured. A good hypothesis for our fertilizer example is: "Corn crops supplemented with 1 pound of nitrogen per bushel will result in a greater yield mass than equivalent corn crops grown with differing nitrogen supplements."

• Timing is incredibly important, so stick to your plan as close as possible. That way, if you see changes in your results, you can rule out different time constraints as the cause of the change.
• Making a data table beforehand is a great idea - you'll be able to simply insert your data values into the table as you record them.
• Know the difference between your dependent and independent variables. An independent variable is a variable that you change and a dependent variable is the one affected by the independent variable. In our example, "nitrogen content" is the independent variable, and "yield (in kg)" is the dependent variable. A basic table will have columns for both variables as they change over time.

• Good experimental design incorporates what's known as a control. One of your experimental replications should not include the variable you're testing for at all. In our fertilizer example, we'll include one corn crop which receives a fertilizer with no nitrogen in it. This will be our control - it will be the baseline against which we'll measure the growth of our other corn crops.
• Observe any and all safety measures associated with hazardous materials or processes in your experiment. [6] X Research source

• It's always a good idea to represent your data visually if you can. Plot data points on a graph and express trends with a line or curve of best fit. This will help you (and anyone else who sees the graph) visualize patterns in the data. For most basic experiments, the independent variable is represented on the horizontal x axis and the dependent variable is on the vertical y axis.

• To share your results, write a comprehensive scientific paper. Knowing how to write a scientific paper is a useful skill - the results of most new research must be written and published according to a specific format, often dictated by the style guide for a relevant, peer-reviewed academic journal.

Running an Example Experiment

• In this case, the type of aerosol fuel we use is the independent variable (the variable we change), while the range of the projectile is the dependent variable.
• Things to consider for this experiment - is there a way to ensure each potato projectile has the same weight? Is there a way to administer the same amount of aerosol fuel for each firing? Both of these can potentially affect the range of the gun. Weigh each projectile beforehand and fuel each shot with the same amount of aerosol spray.

• The furthest-left column will be labeled "Trial #." The cells in this column will simply contain the numbers 1-10, signifying each firing attempt.
• The following four columns will be labeled with the names of the aerosol sprays we're using in our experiment. The ten cells beneath each column header will contain the range (in meters) of each firing attempt.
• Below the four columns for each fuel, leave a space to write the average value of the ranges.

• Like many experiments, our experiment has certain safety concerns we need to observe. The aerosol fuels we're using are flammable - we should be sure to close the potato gun's firing cap securely and to wear heavy gloves while igniting the fuel. To avoid accidental injuries from the projectiles, we should also make sure that we (and any observers) are standing to the side of the gun as it fires - not in front of it or behind it.

• We can even share our results with the world in the form of a scientific paper - given the subject matter of our experiment, it may be more appropriate to present this information in the form of a tri-fold science fair display.

About This Article

If you want to conduct a science experiment, first come up with a question you want to answer, then devise a way to test that question. Make sure you have a control, or an untested component to your experiment. For example, if you want to find out which fertilizer is best for growing crops, you would have one plant for each type of fertilizer, plus one plant that doesn’t get any fertilizer. Write down each step of your experiment carefully, along with the final result. For tips on organizing your data collection, read on! Did this summary help you? Yes No

Making Lab Diagrams Easier to Visualize

When it comes to student laboratory/apparatus setup, one thing is sure to help—visuals. However, many of us suffer from a disorder that makes all our test tubes resemble things we wish they didn’t. In addition, it is often hard to find that perfect image using the trusted Google search. However, it turns out there is a free and incredibly easy tool that allows you to assemble and customize almost any chemistry related setup you wish. Say hello to Chemix !

As described by its developer 1 ,

I use this intuitive app at least a couple times a week.  Sometimes it is just to capture an image of a beaker half full of water so that I can more easily draw particle diagrams on the board, while other times I use it to add clarity to my worksheets, labs, or assessments. 

Image 1 - Introduction to a question from an assessment of mine that Chemix helped improve

As a chemistry teacher, I strongly recommend you take five minutes to explore the awesome features of this useful tool. For Google Chrome users, you can easily add it as one of your Chrome apps so that you don't have to go to the website each time you want to make a diagram.

Image 2 -  Sample Chemix image I made that displays some of the apps cool features.

Check out this demo  for a brief glimpse of how powerful this little tool can be. I should mention that this demo was from 2009—Chemix can do so much more now!
