If light is reflected it is bounced off a surface.

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

A protractor is a piece of equipment used to measure and draw angles.

Scientists look for patterns in data to answer their questions.

The normal line is an imaginary line that is at a right angle to a surface on which light is reflected.

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.

Physical activity and equipment requiring safe use

When light is {{}} off the surface of an object, it changes direction.

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

What piece of equipment is used to measure the size of angles?

Match the unit to the measurement they are used for.
