S2 were looking at sound waves today as part of their telecomms topic. Here they are looking at an oscilloscope. They noticed the change in amplitude and frequency as the made more noise or increased the pitch of their voices into the microphone. The whole class had a good scream at the end to see the effect - fortunately my laptop is still working!
