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

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

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

In this fun science fair project idea learn about the multiple sources of radio waves and fin out how difficult it is to block them.
