In this activity, students use UV beads to investigate the intensity of UV rays in a range of different situations.
By the end of this activity, students should be able to:
- explain that UV rays come from the Sun and can cause sunburn
- demonstrate (through the use of UV beads) that various objects can block UV rays – either partially or completely.
