On Friday, a group of Year 5 and 6 children and I spent an hour outside doing some science. Our question was “How fast does sound travel?”
We didn’t have any measuring equipment at all – we used only string, a bag of stones and a woodblock to work out the speed of sound!
Our final answer was 360 metres per second. The actual speed of sound is 340 so we were very close considering we didn’t use any measuring tapes or stopwatches. (We worked out we were between 5 an 10% out)
We were so busy that we forgot to take any photos – sorry!
How do you think we did it?
