Do your children take part in a science fair or have science projects to do at school or home? Do you need a bit of inspiration to create an amazing science project? I’ve pulled together some brilliant kids science project ideas to get you started!
Kids of any age from preschoolers up to high school kids can enjoy investigating, experimenting and creating cool science projects just for fun or to understand more about chemistry, biology, physics, plants, ecology and more.
If you’re really stuck for an idea, try thinking about a science question to answer and go from there!
Expand on our ideas to make a winning science project everyone will LOVE!
