In science, we have been learning all about sound. We have learnt that sound is made by vibrations. When we make a sound, it vibrates the air particles around us. That's why there is no sound in space! There is no air!


We went on a sound walk around school and heard lots of different sounds.

In the next lesson, we made string telephones. We spoke into one end and our voices sent vibrations down the string and into the other person's cup!

The telephones only worked if we held the string tight and it didn't work around any corners.
