Sound Investigations

Whales class have been completing lots of investigations in their learning about sounds recently. We have been using data loggers to record the volume of sound, and have discovered that sounds get quieter as you move away from the sound source. We have also been exploring how to insulate sounds, and we experimented by wrapping an iPad in different materials and then recording the volume of the iPad’s alarm. We found out that the soft, thick materials were better insulators than the thinner materials. Whales class were also able to recognise that the results of our investigations were not always reliable due to background noises that may have affected the recordings (lots of other children practising their nativity songs was a culprit!)
