Today we learnt about sound. We learnt that sound is vibrations which travel through a medium (air) to our ear. Our eardrum then vibrates and our brain interprets this as sound. We did an experiment which showed us how sound works. We put hundreds and thousands on top of some glad wrap which was wrapped really tightly around a bowl. We practiced the sounds of letters which then made the hundreds and thousands move. Mr B showed us how it was done before we had a turn. The louder the noise we made the more the hundreds and thousands moved. Some even went flying on to the table. Then the best part happened and we got to eat all the hundreds and thousands.
You may like to have a go at doing this at home. Here is a you tube link that explains the process.
