What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

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.

Let your young scientist explore a brave new world of sound with an experiment that just requires a handful of common household items.

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