- 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.
