air quality, ozone, particulates, reactions, physical changes in matter, chemical changes in matter


In class, students learn the difference between physical changes and chemical changes in matter, and then go for a hike to observe both in nature. They learn about particulate matter in the air, discuss what creates particulates, and discover how scientists measure them. They act out the chemical changes that are destroying ozone in the upper atmosphere and see how scientists measure ozone recovery. Back in class, students mix household items and predict the type of resulting reactions.
