Shadows

Science

In the Making images unit, they will build on this knowledge to learn that white light is made of different colours that can be detected by the eye, and how pinhole cameras and lenses form clear images.

In the Light and how it travels (Y6) unit, pupils learnt that light travels in straight lines, which explains why shadows have the same shape as the objects that cast them, and objects are seen by the light that reflects back into the eye or travels directly into it from a light source.
