Our latest sound experiment involved glass bottles all the same size. We filled them with different amounts of water and tapped the bottles with a beater.

We put put the bottles in order by listening to the pitch of each sound. When there was more water the pitch was lower and the pitch was higher with less water. Why not try the experiment at home?

Just a reminder that any Christmas cards can be posted in the Christmas   Post Box and P3 will distribute to the correct classes. The full name and class should be written on each envelope. If you are not sure, we can help the children write the correct class for their friends. One card to the whole class is a good idea as it saves lots of writing!!
