Our new topic in primary 3/4 is all about sound.
We started by looking at the mechanics of the ear, which we found really interesting.
Next we went on a sound walk around the school, recording all the noises we could hear, both loud and quiet.
We know that sound can move through the air, but we wanted to find out if it would travel through string, so we decided to carry out a little experiment using string and two cups. Check out our experiment in the pictures below.
One of the important things we found during our experiment was that the string had to be tight to work.
