Science Investigation

In our science investigation we wanted to find out if sound could travel through liquid, although we were pretty certain it did!

We decided to extend our investigation a little by using three different materials to make the sound under the water.  We chose glass (under strict supervision), stone and metal, as we wanted to check if the pitch and volume levels would change if we used different materials.

We predicted that glass would be higher in pitch and in volume and it was!!
