What we did learning in the science lab

Today we got learn in the science lab about sound, We had to match the sound waves until they were the same.The bigger the waves the lower the pitch and the thinner the wave the higher the pitch.
We had to pluck the string so you could see if the waves were big or small.

We also went on other science labs with lots of instruments like the drums, a pipe and a guitar.
I liked using the pipe. you had to listen to one of the pipe pitch sounds and try and find it on one of the pipes. When you looked at the pipes the longer ones had a low pitch and the shorter ones had a higher pitch .
