How does sound travel?

 

We learnt about how sound travels through various mediums - air, water and solids. We then made paper cup telephones so we could explore how sound waves travel along string, from one cup to the other and then into our ears.

How are sounds made and how do we hear them?

 

Today we started our new Science topic - sound. We learnt about how we hear sounds and how sounds are made. We watched videos showing us slowed down and enlarged versions of different objects making sounds by vibrating. We then investigated seeing and feeling vibrations by different sound making objects- drums, triangles, our voices and tuning forks.
