The children now know that sound waves can travel through air. We can feel and hear the vibrations from sound waves but we cannot see them. I told the children that I have a very special app (Wavepad) on my ipad that someone created to help us imagine what sound waves would look like. The children each recorded their own voice on the app and saw waves. They immediately noticed that some waves are small and some are big. After a few recordings, they started to see that soft voices made small waves and loud voices made high waves.
In addition, the other day when we were creating vibrations with elastic band, Alfie noticed that his elastic band sounds different when it is stretched differently? Why? So the children made their own guitars and we are going to investigate why do the strings make different sounds?
