As part of our inquiry into music leading into the upcoming music festival in week 5, we have been doing rotations looking into different aspects of sound and music. One of these has focused on how sound works... Sound is made when something moves or vibrates. The movement sets up a sound wave in the surrounding air.
We have been observing slinkies to see some of the properties of sound waves - how they vibrate, how they lose energy as they touch or move through things and how the wave reflects or echos. We've also been looking at how we can hear. Ask one of us if we can tell you how our ears work or which part of our body vibrates when we talk.
