In this activity, students use the UVB Sensor to measure the amount of UVB light that passes through a thin film of sunscreen. They analyze the relationship between the SPF values and the intensity of UVB light transmitted by the sunscreen.
The initial graph made shows that the intensity UVB light without any sunscreen is many times greater than with the lowest SPF sunscreen.
Graphing the UVB intensities of just the sunscreens gives students a better way to compare sunscreens.
