TLF ID L1138
Use a simulator to test the level of ultraviolet (UV) rays. Test the effects of cloud, shade and ground surface: grass, sand, water and snow. Notice that the amount of UV light that reaches a person varies according to the reflectivity of their surroundings. Use simulation results to answer a series of questions. For example, identify conditions where increasing cloud cover may actually increase UV exposure. This learning object is one in a series of two objects.
