Using Mass Balance to Understand Atmospheric CFCs
Students use an interactive online mass balance model to observe levels of chlorofluorocarbons over the past few years. Students evaluate the influence protocol emissions will have on the future levels of CFCs.
Curated OER
The No Zone of Ozone
Students explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. Using gumdrops and toothpicks, they conduct a large-group, interactive ozone depletion model.
