Science

In the Waves unit, they will build on this knowledge to learn about the properties and propagation of transverse and longitudinal waves.

In the Sound, light and vision unit, pupils learnt how sound waves travel through different types of medium and are absorbed and reflected, how light is reflected off mirrors, and how the eye can see objects by the light they reflect.
