This science fair project idea explores the relationship between oil and water in terms of density as well as hydrophilic/hydrophobic compounds.

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

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

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

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.

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.

Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

Here's an interesting activity that will enable your child to make his own magnifier out of a drop of water

This project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

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.
