Light

Background Information
In this unit the children will work scientifically to explore the different uses of light. The children will be using both natural and man-made light sources to help with their investigations. The children will explore how shadows are created, and will discuss which materials are able to create shadows. The children will understand that we are able to see things due to light. When light hits an object it is reflected back and enters our eyes.

In this unit the children will…
Explore the different uses of light.
Discuss which materials allow all light through, some light through and no light through.
Create an item which will be reflective.
Use animation to explore different reflections.
Create objects which will create a reflection.

By the end of this unit….
All children can:
Recognise that they need light in order to see things and that dark is the absence of light
Notice that light is reflected from surfaces
Recognise that shadows are formed when the light from a light source is blocked by a solid object
Recognise that light from the sun can be dangerous and that there are ways to protect their eyes
Most children will:
Find patterns in the way that the size of shadows changes.
Setting up simple practical enquiries, comparative and fair tests
Gathering, recording, classifying and presenting data in a variety of ways to help in answering questions
Some children will:
Reporting on findings from enquiries, including oral and written explanations, displays or presentations of results and conclusions
Making systematic and careful observations and, where appropriate, taking accurate measurements using standard units, using a range of equipment, including thermometers and data loggers
Using results to draw simple conclusions, make predictions for new values, suggest improvements and raise further questions
