Lesson overview
In this lesson, you explore how light becomes colour, how your eye processes it - and what happens when you spend too much time in front of a screen. You start with a prism poll and a visual illusion, investigate as one of three specialist groups (Scientist, Engineer, or Health Expert), synthesise your findings, and propagate your learning to the class through a presentation and a Wonder Map.
Group A - Scientist: Investigate how photoreceptors (rods and cones) work and explore colour blindness simulators.
Group B - Engineer: Build with light - explore RGB colour mixing, pixel zoom and hex values.
Group C - Health Expert: Investigate the effects of screen time and create a habit checklist.
