Lesson details
Key learning points
- When light travels towards a surface and bounces off it, this is called reflected light.
- A data logger can be used to record the amount of light reflected from different surfaces in lux.
- The results of an investigation can be recorded in a table and used to make decisions about different materials.
- The best surfaces for reflecting light are very smooth, such as a glass mirror or polished metal.
- Scientists evaluate every stage of an investigation to suggest improvements.
Keywords
Reflect - To reflect light is when light hits a surface and bounces off.
Surface - The surface is the top or outside layer of something.
Result - The result of a test or enquiry is what happened or what was found out.
Evaluate - To evaluate is to think about what you did and suggest any changes or improvements.
Improvement - An improvement is when something gets better or when you make it better.

All materials reflect the same amount of light.
Explanation that we can measure the differing amounts of light reflected by different materials.
