- Students will develop an understanding of how the Earth's atmosphere
(stratosphere and ozone layer) shields the surface of the Earth
from most of the ultraviolet rays that come from the Sun.
- Students will explore/demonstrate the effects of ultraviolet
radiation on objects that react to ultraviolet rays.
- Students will familiarize themselves with the electro-magnetic
spectrum to understand where visible and ultraviolet radiation
fall within it.
