We can detect with our eyes in order to see things.

Something that is a light source produces its own light.

To record information is to keep it so that it can be passed on to others. This can be done in many ways including notes, tables, photos and drawings.

A diagram is a simplified drawing of information.

How light travels

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.

Light and how it travels

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.
