Sound In Science
In Year 4 we have been learning about Sound in Science this term.
Sounds are made when things vibrate. A vibration is a quick movement that makes a backwards and forwards motion. Sound has different volumes and pitches and the size and shape of the sound waves determines the kind of sound we hear. Animals such as bats, dolphins and whales use Echolocation to help direct themselves through their surroundings. Echolocation is the process of using sound waves to find objects that are not in sight range.
The Year 4’s have been investigating what causes pitch to change and how one can create music using that. They are now building their own creative instruments which need to be created from recycled materials and built in class. The students are not only learning from the teacher regarding the topic but they are also able to teach themselves when it comes to practical tasks such as this.
At this stage they are still busy building their own musical instruments and we are all very excited to see the final outcome.
