We noticed that the sound got less loud if we were a long way away. So, we decided to design a fair test to prove that the further away the sound, the quieter it is.
We used a sound meter app to measure the sound a tambourine made at different distances going up in one metre increments. The children had different jobs such as tambourine player, measurer, sound meter reader and results recorder.
Once we had recorded all our results in a table, we noticed that the number on the sound meter went down the further away the tambourine was played. A couple of results didn’t fit the trend, so we repeated the experiment exactly the same way again. The second set of results showed that our prediction was correct.
2M have really enjoyed bringing Science to life with lots of hands on investigations and experimenting with different instruments.
