Primary School of the Year 2022
Hi my name is Ciara and yesterday we were doing science in class in the afternoon. This is what we did, we got a bowl and put plastic over it and put sugar on and banged a drum loud and the sound made the sugar move. We learned
that sound is faster in water and if someone bangs the wall quietly you can hear it far away. We did three other experiments.

Yesterday we where learning about science. One of the things we learned was if you put your ear to something metal and get your friend to hit something hard on it you will hear it faster than through the air. If you put your ear to the wall and get a friend to hit it round the corner you can hear.

We did some experiments on sound today. We learned that sound travels 15 times faster through metal and bricks than air. In the ear there is a little bone that sends signals to the brain, it tells it if it’s a high sound or low, loud or quiet and the bone is above the ear drum. Sound is shock wave of vibration. We did an experiment on making something move without touching it. First you get a bowl and wrap it in cling film, second put sugar on it and then get an instrument and bang it and the sugar moves.

Hello, my name is Jodie, and our new Topic is sound. It is interesting because we did an experiment. You get a
musical instrument and and a drum and put salt on it and bang the instrument and the salt should move and I learned when you speak sound waves come out.

Yesterday we were learning about Science. Two interesting facts I found out were that sound travels eighteen times faster through
metal than air and if you want to measure sound you have to use a Oscilloscope.
