Year 4 – Science - Sound

Sound travels as a wave, vibrating the particles in the medium it is travelling in. So in our example, when she hit the drum, the drum skin vibrated. This made the air particles closest to the drum start to vibrate as well. The vibrations then passed to the ... C thunder D No sound.

SOUND INSULATION - INVESTIGATING WHICH MATERIALS …

Sound is a vibration – it needs something to pass on these vibrations (unlike light which can pass through a vacuum). Some materials allow sound pass through them very easily, especially hard rigid ones like metals. Other materials, especially soft ones like cotton wool, absorb sound. Ears are delicate and need to be looked after.
