How does sound travel?

Lesson: Science

Class: Y4 Year: 2017 - 2018

In our Science lessons, we have been learning about sound. We have been looking at how we hear sound and how sound travels. To identify how the pitch of a sound changes, we made pan pipes with straws and tried to change the pitch by adjusting the size of the straw. To help us understand how sound travels we made string telephones. We found out that if the string was tight we could hear better. Here are some pictures.
