P4/5 science.

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.

Science And Experiments

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.
