Our Science topic for this half term is Sound (physics). Last week, we went on a sound survey and assessed the noisiest place in school. It was the playground because this is near the road.
This week, we’ve been learning all about how sounds are made.
Here’s a summary …
When any object vibrates, it causes movement in the air particles. These particles bump into the particles close to them, which makes them vibrate too, causing them to bump into more air particles. This movement, called sound waves, keeps going until they run out of energy.
Using instruments, drums and beaters, rice and lentils against plastic, we explored the sounds we could make. We also tried aking sounds with our bodies. It’s such fun exploring music and sound!
Finally, we discussed making sounds louder and quieter depending on how hard or soft you hit them.
