# Unit Review: Key Concepts
  • Sound is a vibration.
  • Sound needs something to travel through, like air, water, or a solid.
  • Sound waves have different wavelengths, which result in different pitches.
  • Higher-pitched sounds have shorter wavelengths.
  • Lower-pitched sounds have longer wavelengths.

In today's activity, you'll use what you've learned about sound and sound waves to build a device that uses the vibrations of sound to make visible patterns.

You’ve been invited to make an exhibit for the International Museum of Interesting Sounds. The museum wants to fill a room with devices that make sound waves visible. It's up to you to design, build, and test your unique Sound Wave Watcher for the exhibit.
