Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

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.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.
