If you’re looking for science projects for kids, I have a mega list for you that’s 100% kid-tested.

My children and I have worked our way through a LOT of science projects over the past few years, so I compiled them into one easy-to-find spot. If you’d like more ideas like this, you’ll love my best-selling book, TinkerLab: A Hands-on Guide for Little Inventors.
Most of these science projects and experiments will be engaging for children ages 3 and up, although I did MANY of them with my 2-year olds.
Science Projects for Kids
These projects fall into five categories:
Magical Plastic Bag Experiment: Learn about the magic of polymers as you poke pencils through a water-filled bag…and notice that not a drop of water leaks through the holes!
Magnet Magic: Move Paper Clips through Water with Magnets
Is it Magnetic? Testing objects for magnetism
How to Make Gak (Slime): This recipe is amazing and so much fun to play with
Growing Gummy Bear Experiment: Fill a small bowl with water, drop in gummy bears, and see what happens. Extend this into an experiment by replacing the water with other liquids, or replacing the gummy bears with other candies.
Dry Ice Experiment: Fill a metal container with a small piece of dry ice and water, and let the experiments begin!
How to Make Natural Dyes: These are great for egg dyeing
Microwave Marshmallow Experiment: What happens when you microwave a marshmallow?
Rock Candy Experiment: Make your own rock candy with sugar and water.
Yeast and Sugar Experiment: Fill a bottle with a combination of yeast, water, and sugar, cover the bottle with a balloon, and then watch the balloon grow as the yeast reacts to the sugar-water mixture.
How to Make Curds and Whey: A Science Demonstration
Lava Lamp (below): A wild mixture of oil, water, and the magic ingredient: antacid tablets. This activity is in my book, TinkerLab: A Hands-on Guide for Little Inventors. The link will take you there!
