We all know we can hear sound (although you could say Phil's hoodie is LOUD)...but how exactly does it work? It's time to find out in another Hub Lab!

Sound is a type of wave. A soundwave is a type of vibration that moves through the air. When we hear something, its because our eardrum is vibrated by the sound waves that have moved through the air, and different vibrations make different sounds.

Learning Objectives...
1. How sound works.
2. Waves and vibrations
3. Speakers and music


As ever Phil has a cool experiment for you to try out at home, or in school with all your class. You can watch it in the video and get the instructions and what you will need here...
