SOUND

We had an amazing science lesson about sound. We were asked what is sound? We gave lots of answers:

* A noise

* Sound Waves

* Sound is in the air

* Sound is energy

We used cup telephones for our experiment, we learnt that if the string was tight and we held the cup with

only two fingers we were able to hear our partners speak clearer.

Next, we were asked to hold a balloon with our fingertips. When someone made a noise next to it the balloon

vibrated, this was because the sound was causing the particles to move.
