Ultraviolet Lab Today & Constitution Test
Seniors went outside today (enjoying the sun) to use UVB sensors to measure UVB light. The objective was to determine the percent UVB light that is blocked by various kinds of sunglasses and regular eyeglasses. There was no difference in "cheap" sunglasses vs. "expensive" sunglasses in their ability to block UV radiation.
While seniors did the science experiments Juniors worked on a U.S. Constitution exam.
