Fun and Easy Science Experiments for Kids at Home

Save this idea for later!

Stuck at home with the kids? No need to panic.

There are tons of STEM activities and science experiments you can do at home that are perfect to keep kids away from screens and occupied indoors in a way that won’t rot their brains.

These fun science experiments for kids at home don’t require any weird supplies (because even Amazon is running out of things), and you can do them with things you likely already have at home!

Supplies for Science at Home

If you have never done a science experiment at home before, or if you’re new to STEAMsational, you may not realize just how many science experiments you can do at home!

We’ve spent the last few years creating at home science experiments (many of them in jars, by the way), that all use household supplies.

Before you start these at home experiments, you may want to make sure you have at least these things on hand:

We end up doing a lot of our science experiments in jars, just because jars are easy to find and you probably have a few in your kitchen.

But if you’re not a jar hoarder like I am, then you can use regular water cups.

I recommend using glass over plastic, just because some of the chemical reactions or food coloring might ruin a plastic cup.

A lot of our at home science projects use food coloring, salt, oil, vinegar, baking soda, or corn starch.

If you find you don’t have the supplies for a project, you can try something else or try to order the products online.

How to Do Science at Home

Science at home isn’t as much about the “facts” side of science. At home, you’re not usually working toward a test or a set of standards, so there is more freedom to explore and have fun with science.

If you’re new to doing science at home, there are a few secrets that will help you stay sane, and maximize the effectiveness of your projects.

easy at home science experiments

Keep it Simple

Simple science experiments are better at home. Doing an experiment or science demonstration on one theme at a time will provide the most value.

Not everything has to be an elaborate, full-scale science experiment with four variables a strict data recording sheet, and multiple tests. Just having fun and exploring the topic is just as beneficial at home, and more so, in some cases, if your children love to explore, but hate to record.

Don’t make science a chore; keep it light, fun, and simple!

Embrace Mess

Hands-on projects lead to messes. It’s a fact. Place your science area in a part of the house that can get messy and take some deep breaths if the mess bothers you.

Focus on Exploration

You don’t have to worry about kids “learning” when you’re doing these science experiments at home.

Research shows that when kids engage with something through a hands-on activity, they retain that information longer, and more clearly than a child who doesn’t do a hands-on activity.

This is true even if it doesn’t appear like the child is “getting” the lesson. When you do activities with your child, let them explore and you provide simple explanations and vocabulary along the way.

That’s all you need to do!

Follow Your Kids’ Interests

You may like coding, but if your kids don’t, trying to force them to do coding activities for kids won’t end well.

Try to pick experiments that match your child’s interests. Do colorful projects if your kids like color. Do earth science if your kids are interested in how the earth works. Do gross science if your kids like that.

The more your kids are into the topic, the better your experiments will go!
