Oh no, I have to do a science project!

As a parent, I loved it when my kids brought home paperwork that clearly stated how to do the assignment, what the rules were, and what the timeline should be. We gotta know what’s going on, right?!

Unfortunately, the first science fair that my son entered was mandatory, and didn’t come with any instructions at all! Oh, no! We were left to do what many kids and their parents have to do, muddle through the internet for ideas.

When I became a K-6 science teacher, the many teachers I worked with all agreed that the basic, easy science fair steps included working step-by-step on The Scientific Method.

The Scientific Method


The question is the basis for the experiment. So, make sure it is a testable question! Don’t start with “Why” because it is very hard to figure out why. It is much easier to answer a question that begins with “Which” or “How many” or “How tall”.

Ask a question that measures something.

Examples: Why does a plant grow? Too hard to figure out from an experiment. Which fertilizer makes a plant grow the tallest? Much easier to make an experiment out of this by measuring height. How many drops of fertilizer make the plant grow the heaviest zucchini? Also good for an experiment measuring weight.


In the primary grades, you don’t need to do a significant amount of research. Your research might include an interview of someone, something you observed, or just some interesting facts that you found out about your subject online. Write it up in bibliography form using easybib.com.

Make sure the question you are asking doesn’t already have an explanation online or you wouldn’t need to do an experiment on it!


Form a hypothesis, or educated guess, on what you think will happen in your experiment. Your hypothesis should take a form similar to this…

If I (do this)….Then (this will happen)…Because (I read…, somebody told me…)

Example: If I fertilize roses with banana peels, coffee grounds, or eggshells, then I think the roses will have the most flowers when planted with the banana peels. I think this because I read in this article that banana peels help roses produce more blooms.

Does it matter if your hypothesis fails miserably in your experiment? Absolutely not! So, don’t go changing your hypothesis at the end.


The materials are all the stuff you use in your experiment. Include a list of detailed metric amounts. If you only have standard American measuring devices, just use these metric conversion charts. These charts also give great ideas on things you can measure in your experiment – like volume, temperature, speed, length, and angle.

Example: 3 liters water, 100 grams soil


The procedure is a step-by-step numbered list of all the things you need to do to repeat your experiment. It is exactly like a cooking recipe, where the ingredients are the materials and the directions are the procedure.


While you are doing your experiment, you need to be measuring something and writing the measurements down. This is your data. Make it into some neat charts, then make those charts into graphs. For the graphs, it is easy for kids to use Create a Graph.


The results are the place you explain the numbers in your charts and what you are showing on your graphs. It is what you found out in your experiment.


The conclusion is where you bring your whole experiment together and communicate what you learned. You explain whether your hypothesis was correct, and why not if it wasn’t. And, you tell everyone why this experiment is important in the real world. (Yes, your experiment should have a real purpose).

Below is your cheatsheet on How to do a Science Fair Project: Easy Science Fair Steps telling you what you need to get your first science fair project done. I wish I had these papers when my son was starting out with his first project!

The Rules

Teachers usually follow the rules and guidelines of the International Science and Engineering Fair (ISEF). The basic rules for primary grades are – don’t experiment with anything hazardous and don’t experiment on humans or animals unless you get permission first.

Science fair experiments are scary if you don’t know what’s expected. Normally, a 6 to 8 week timeline is a good one for elementary or middle school projects, so stay on track. Hopefully this info will make it a bit easier. Download them now and let me know if they helped.
