This fun marbled paper craft uses things you're likely to have around your house, and it teaches kids some simple chemistry too!

This experiment investigates whether there are certain sounds that affect men and women differently

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

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.

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.

I scream, you scream, we all scream for homemade spearmint ice cream!
