In this cool engineering science fair project, kids learn how to build Hero's engine: an enlightening example of Newton's third law.

This project compares the strength of one, two, and three-ply toilet paper.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

In this design thinking activity, your child will choose an animal to research, learn about the animal’s habitat, and then replicate the animal's habitat using household items.

In this fun activity, your child will create their very own solar oven to bake s'mores!
