Stratospheric Ozone An Electronic Textbook with low- and high-resolution graphics and review questions
http://see.gsfc.nasa.gov/edu/SEES/strat/class/S_class.htm

This is a site devoted to ozone and ozone lessons.
http://www.cotf.edu/ete/modules/ozone/uvmenace.html

This is a lesson on how much ozone is over your head at any given place and time.

These are five projects designed for independent research for high school students on what's going on with the ozone layer. Using these independent research projects, students can obtain additional information.

CHEM is a NASA project that will measure ozone and the ozone-destroying radicals from nitrogen, hydrogen, and chlorine compounds. CHEM will determine whether the stratospheric ozone layer is now recovering, as predicted by scientific models. CHEM will also measure the amount of UV radiation that reaches the Earth's surface.
