Gigantic List of Science Experiments

Keeping kids entertained can be a full-time job! I definitely think they should be allowed to be bored at times to spark creativity– but we still have our work cut out for us filling the rest of the day with productive activities. To help with that, I’ve compiled a huge list of science experiments for kids!

Science experiments are a major win-win in my opinion. Most kids LOVE seeing the cool reactions that occur, and they don’t even mind that they’re learning too! Haha.

Since many are homeschooling at the moment, this can be a perfect way to add some educational fun to the day. And many of these activities incorporate other STEM skills as well!

You’ll find over 125 science experiments to keep those kiddos busy for the rest of the school year and summer! They’re broken into groups based on the type of experiment to make it easier to search through. And you probably have many of the ingredients/materials already!

Most of these experiments are easy to complete and can be enjoyed by a range of ages. The more difficult ones have an asterisk (*) to indicate that they are better suited for older kids, or would require you to be very involved for the youngins. Everyone likes a good challenge, right?


Every good science experiment makes us think about how and why it resulted the way it did. Add some extra learning to your activities by using the Scientific Method printable below!

Sign up at the bottom of this post to get a Scientific Method printable sent to your email! Print one out for each experiment. It will help your kids think more critically about what they’re doing, learn more about cause and effect, and give them a way to look back on all the cool stuff they did! 

Be sure to wear safety goggles, gloves, and BE CAREFUL with some of these ideas. An adult should definitely be present for any involving fire. Ok you little mad scientists– get to experimentin’!

Don’t forget to download your Scientific Method printable to fill out before each experiment! In case you’ve been out of high school for awhile (like me), here’s a quick refresher on the steps involved:

1. Make an observation. 2. Ask a question. 3: Form a hypothesis. 4: Perform an experiment. 5: Record your results. 6: Draw a conclusion.
