For a science experiement we constructed a communication object from 2 cups and a string. The children tied string to the end of paper cups. The string had to be at least 20 metres long. The children had to stand apart from one another (a vast distance) and the string was not allowed to touch any objects. One child would whisper into the cup while the other would listen.
The children were suprised to find there objects worked. We discussed ideas, how does this work? Why can sound be heard from a vast distance?
Jakob was able to make the connections that the vibration of sound would travel along the string to the other cup.
We then predicted would the sound be able to travel up. For example, the children wanted to find out 'what if someone was at the top of the playground the other on the ground, can the sound travel up?' (as gravity might stop this- this related to our unit in term 2).
We were suprised to find that the sound sometimes would travel but it was hard to hear, or it would not work at all. We acquired a different result.
Great inquiry learning room 4!
