This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

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.

Using a toy race car kids create a visual model of the Doppler Effect.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.
