Clever and Fun Science Projects for Kids at Home

If you’re stuck at home right now, you may be wondering how to incorporate science at home. While some schools are doing a good job of adding science instruction, some schools don’t seem to be as on top of things as others.

If you feel like your kiddo would benefit from additional hands-on science projects (and we’re always a fan of that!), then you’ll love this list of science projects for kids at home.

But don’t worry, these science projects will also work for science fairs whenever those are back up and running!

If you're looking for hands-on science projects (and we're always a fan of that!), then you'll love this list of science projects for kids at home.

20+ Science Projects for Kids that are Easy to Do at Home

You don’t really need any special supplies for these at-home science projects, and even better, they don’t use yeast, so you can save that for cooking when your stores run out of bread!

These simple science projects work best with kids between second and fifth grade, but if you have a middle schooler at home don’t be surprised if they want to join in!

And if you have younger kids at home, you’ll want to try these science experiments for preschoolers.

What is the difference between a science project and a science demonstration?

science projects with hypothesis

You see a lot of science experiments online (we have a huge bank of science experiments for kids), but not all of them are true *experiments.* Some of the science experiments that you read about are actually science demonstrations.

A science demonstration is an activity that kids can do that illustrate a specific scientific concept. Many of the science experiments that we have are more similar to a science demonstration because a single set of directions is given.

For something to be a true science experiment or science project, the children must follow the scientific method.

There should be a question, a hypothesis, variables to test, and then a report on the findings. This is what makes a true science project.

The Scientific Method for Kids

There are four parts to the scientific method:


Every experiment starts with a question. A lot of experiments start with “what happens when” questions. Questions like “does X work better than Y for completing Z?” are also a popular format.


A hypotheis is an idea of what the results of the experiment might be. A child might guess that water would freeze faster if it was already cold, for example.


Here is where you test variables against a control group to see if the hypothesis is true or not.

Report or Conclusion

In the report, kids report their findings and identify if the experiment proved or disproved their initial hypothesis. Older kids can run additional tests, but most elementary kids stop at one round of testing.
