We have rounded off our Science topic on sound this week by investigating pitch.

Frist we got out the glockenspiels and investigated how the pitch of each note was different and why that might be. We concluded that the pitch changed depending on the length of the keys. The longer notes were a lower pitch and the shorter notes were a higher pitch.

We then put this knowledge to use in making our own set of panpipes. We had to cut paper straws to different lengths to make pipes that made different pitched sound. We then tested them out to see if it worked!
