Pupils should be taught to:
• recognise that light appears to travel in straight lines;
• use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye;
• explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes;
• use the idea that light travels in straight lines to explain why shadows have the same shape as the objects that cast them.
A PowerPoint presentation used to introduce pupils to light and the range of light sources, natural and artificial that produce light. The PowerPoint can be used at the beginning of the topic or during it to stimulate scientific discussions, ideas and theories.View Resource

Pupils learn about the main structures of the eye and the jobs they carry out. They learn how the eye works and enables us to see.View Resource
Pupils learn about the structure of the eye by completing a cross sectional diagram. They learn that light reays are reflected into the eye and this is what helps us to see.
Pupils learn about the structure and function of the eye and how it helps us to see.View Resource
Pupils learn about the basic structure of the eye.View Resource
Pupils learn that we can see things because light rays from a light source reflect of objects and then enter our eyes. They learn about the basic structure of the eye and how it allows light rays to enter it and form an image on the retina.
Pupils investigate the formation of shadows and how the shape and size of a shadow can change according to the position of the light source, object and surface producing the shadow.
Pupils investigate how shadows are formed and how the position of the light source and the object creating the shadow have an effect on the size and shape of the shadow.
Pupils learn that objects that do not produce light but can still be seen in the presence of a light source are called 'reflectors'. Pupils complete an investigation into a range of reflectors and learn that some materials are better reflectors than others. Pupils also learn that reflective materials can be used for a range of different jobs.
Pupils learn that mirrors reflect light and that mirrors can be used for a variety of purposes. Pupils then investigate what happens to a beam of light when it shines onto a mirror from a number of different angles.
Pupils learn that light travelling from a light source will always travel in a straight line and that light reflecting off an object, reflects off it at the same angle it shines onto it.
