Year 4 enjoyed a fun-filled topic, ‘Playlist’ for this term, where they researched different instrument families and the sounds they make. They learnt that the ear is made up of three different sections that work together to collect sounds and send them to the brain: the outer ear, the middle ear, and the inner ear. Year 4 explored and investigated how vibrations lead to sounds. They tested certain instruments, and noticed that when any object vibrates, it causes movement in the air particles which cause them to bump into more air particles, thus making sound.
