Year 4’s science topic this half term is SOUND. The children this week learnt how sounds travel to your ears, starting as vibrations from a sound source which bump air particles, which in turn bump other air particles. These particles create a ripple of vibrating particles carrying the sound and eventually finding their way to your ear.

Year 4 tested this with bowls of water and a tuning fork, which they enjoyed whacking and putting in the water to see the effects. When the tuning fork was struck and dipped in the middle of a filled bowl of water, the vibrations made ripples in the water that travelled outward until reaching the edge of the bowl.
