Discover the awesome power of sound!

Create sound waves in a tube. Match mystery sounds. Test your hearing. Sort high and low pitches on a turntable. Can you locate a cricket and cat in a kitchen just by listening? Mix a soundtrack. Launch a sound wave toward an eardrum. How many decibels can you produce with your own voice? Team up and let out a roar in the Scream Chamber!

Learning goals:

Sound waves are all around us.

Sound waves hit our eardrums and send signals to our brains.

Sound is measured in decibels and pitches.

You can measure your own voice in the Scream Chamber, and compare your decibels to a friend’s.

When you test your own hearing, you may discover that your left and right ears hear differently.

If you listen carefully, you can find something by using just your ears.

Learn how to protect your hearing for lifelong health.
