This track is designed to go with "The Chemistry of Air Pollution," the second lesson in the Clean Air Campaign’s “Elements of Air Pollution” unit.  For full text of the lesson plan as well as student worksheets and lab report form, go to www.cleanaircampaign.com.  In the lesson, 8th grade students explore elements and compounds which form the major types of air pollution resulting from auto and power plant emissions, by playing an interactive computer game, undertaking Internet-based research, playing Ozone Tag simulation games, and conducting a hands-on investigation of acid rain.  This track provides information for student research.
