Short description
Students learn about the structure of the atmosphere and the oxygen chemistry responsible for producing the ozone layer.
Long description
Rowland and Molina s two-step chlorine-catalyzed cycle, the unique Antarctic meteorology, and heterogeneous chemistry complete the story of Antarctic ozone depletion. Using chemical kinetics in a real context is emphasized through rate concepts and calculations that answer relevant questions about ozone. Students also learn to support or refute a scientific hypothesis with evidence and to consider the interplay between experimental data and theoretical models.
