What can you hear?

In Science this week, we have been finding out how sound travels to our ears. We have been investigating vibration and sound-waves travelling. We conducted two experiments.

We put some seeds on a drum and investigated what happens when then skin of the drum vibrates a little and a lot. We also found out how this affects the loudness or quietness of what we can hear. We found out that the seeds jumped high when the drum was played loudly, meaning that the skin of the drum was vibrating a lot. We enjoyed these noisy experiments!
