Lesson Details
Key learning points
- Reflection involves a source of light and a surface.
- Light travels towards a surface and bounces off it.
- We often see things because light travels from light sources to objects and then to our eyes.
- Scientific diagrams and models can be used to show how we see reflected light.
Common misconception
Light shines out of our eyes; a light ray is a long thin piece of light; light is made of light rays added together; light can only be reflected off shiny surfaces.
Explicit teaching about sources of light, what a light ray is; plenty of demonstrations and practice of drawing diagrams.
