Our teacher decided to show us some instruments known as bull Roarers for the first week of term 4. We were each chosen one by one to chose a piece of wood ( resembling a bull roarer ) and tie it to some string. We then went outside to test them out - that's when the noise came in. Many different sounds of different volume. Afterwards we all shared which ones we thought worked best ( long and thin ) and if we wanted we could take them home.
This was the first experiment we had to do with our study of energy. It was a great way to learn about force and energy.
