Lesson details
Key learning points
- We need light to be able to see things.
- Light travels out from a source of light in all directions.
- Light travels in straight lines.
- Scientists use diagrams to show light travelling in straight lines .
Keywords
Light - We can detect with our eyes in order to see things.
Light source - Something that is a light source produces its own light.
Record - To record information is to keep it so that it can be passed on to others. This can be done in many ways including notes, tables, photos and drawings.
Diagram - A diagram is a simplified drawing of information.
Common misconception
When children think of light, they do not necessarily think of it as travelling. Also that light is found only in bright areas and not in the space between.
Provide opportunities for children to think of different ways to model and record travelling light so it is seen as a continuous straight line.
