Lesson Details

Key learning points

A shadow is a dark shape made when light is stopped or blocked by an object.
Scientists use drawings and diagrams to help share their ideas with other people.
A shadow will be cast on the opposite side of an object where the light source cannot shine.
The position of a shadow depends upon the position of the light source, i.e. the direction of light.
Scientists use test results to make predictions and set up further enquiries.

Common misconception

Children may think that a shadow is cast in between the object and the light source.

Children need to explore shadows cast by different light sources in different positions and with different objects. They should note the position of the light source in relation to the object and the shadow each time.
