If light is reflected, it is bounced off a surface.

Direction is the path that something takes to reach a particular place

A model is used to describe something that can't be experienced directly.

An angle is the space between two straight lines which join at a vertex or point.

A periscope is a piece of equipment that uses angled mirrors to enable you to see over walls or around corners.

Changing the direction of light

Science

In the Light and how it travels unit, pupils learn that light travels in straight lines and how objects are seen. In the Sound, light and vision unit, they will build on this knowledge to learn more about how light is reflected off mirrors, and how the eye can see objects by the light they reflect

In the Introduction to Light and shadows unit, pupils learnt that shadows are formed when the light from a light source is blocked by an opaque object. In this Light and how it travels unit,  pupils will build on this knowledge to use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them

This unit explores how light travels in straight lines, explaining how we see objects and why shadows form the shape of the object casting them. It focuses on planning scientific enquiries, taking precise measurements, making predictions, and evaluating evidence to present findings.
