The National Park Service Air Resources Division has developed a series of activities for grades 6-8 to help teach students about acid rain. The site consists of links to the background of the lesson plan and the five activities designed for the students. Time required for each activity is shown. Lessons cover the pH scale, the difference between an acid and a base, gases that contribute to acid rain, how acid rain is measured and monitored in the U.S.A., and understanding weather maps and the importance of storm tracking. Each of the pages can be printed individually or the entire lesson plan can be downloaded as a PDF.
