In this self-directed and interactive webquest, students explore air quality, air pollution, human-environment interaction, and human carbon footprints. First, students use a governmental website to explore the Air Quality Index ( AQI) and particulate matter. In the second stop, students take an interactive survey that analyzes their lifestyle and calculates their carbon footprint - how many earths it would take to sustain their lifestyle. In a third stop, students investigate the difference between good and bad ozone. In the fourth stop, students use the "smog city game" to experiment with the different factors that affect smog levels. They are challenged to save smog city from smog and challenged to make smog city as dirty as possible. The webquest activity is engaging, exciting and real-world relevant. It gives students purpose and meaning in their classroom work. The webquest encourages students to be self-directed! It is aligned to 7th-grade science essential standards.
