Room 15 – learning about sound – Energy and Forces

The boys and girls in Room 15 were learning all about sound and how it travels. They were learning about measuring sound and decibels.

They made really super string telephones and were able to communicate with each other down the string telephones using vibrations through the string. The sound that was created by the string was then amplified through the cups at either end.

They could pass messages to each other clearly!

It was great fun.

  1. We put cups to geather like ∆——–∆∆——–∆
    The ∆ repersents the cup and the — represents the string and it was at least 20 ft long and it still worked 😊
