Activity Summary

This activity is based on the EPA’s air quality and weather simulation “Smog City 2”. After a brief introduction to the simulation, students explore how different variables centered around emissions, weather, and population affect air quality. This if followed by a discussion to summarize what they learned from the simulation.
