Activity 4 (Explain): The Criteria Air Pollutants
Switch to Dark Mode
In this activity, students learn about the 6 Criteria Pollutants defined by the Clean Air Act and the EPA, and they are introduced to sources of these pollutants. They use this information to think about what pollutant could be the cause of the haze in their pictures. Then they learn to look up current and historical AQI data to identify the pollutant that caused the haze in their picture.
