Juniors explore pitch

When you listen to sounds you will notice that some are high and some are low. This is called PITCH.

These photos show some of the fun students had exploring pitch.

The more air in the tube the lower the pitch of the sound.

If the jar has only a little bit of water the sound will be high pitched when you tap it.

The shorter the straw the higher the pitch.

Here is a story that Jing Qiao (Year 1) wrote about what she learnt about pitch.

On last Friday we went to A7 to learn about pitch. I used straws and paper. I blew over the straws. They made different sounds. One was high and one was low. One is medium. We cut the straws tall and low.
