Colour (light) - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 7 class.
This is the 6th and final lesson in “Chapter 3 - Light” from Activate 1, Physics. This lesson focuses on ‘colour’.
This lesson should be suitable to teach to any KS3 Physics class, even by those where physics is not their specialism.
This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks.
This lesson includes a short practical where students pass white light from a ray box through a triangular prism.

From this lesson, students should be able to:

1. Describe how white light is dispersed when it passes through a prism
2. Explain why white light is dispersed when it passes through a prism
3. Explain why objects have certain colours
4. Recall the primary colours of light and secondary colours of light
5. Describe the colour of light that will be seen when primary colours of light are mixed
6. Identify the colour of light that will be seen when different coloured lights are passed through different coloured filters
