Showing Results for physics marble

Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

Delight your budding scientist with this cool physics magic trick and teach her some basic physics concepts while you're at it!

Your child will do a fun science experiment using soap and pepper flakes to help understand the concepts of water molecules and the surface tension of water.

Your second grader will love this simple soda bottle race car activity. Make a ramp and customize your car for an entertaining way to learn scientific concepts.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This classic children's game demonstrates how sound travels through air vs. through a solid.

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.
