We enjoyed trying out the guitars, finding out about how they work and then doing an investigation using a box and different size elastic bands. We found out that the shorter the band the higher the pitch of the sound it makes when plucked. This is just like a guitar when you twist the tuner, you make the string shorter.
The sound waves are closer together when the pitch is high.
