Air pollution takes many forms - from particles of soot large enough to see, to individual molecules of ozone and nitrogen oxides. Air quality measurements let people know when the amounts of pollutants pose a health risk. This teaching box is filled with educational resources that help students explore the science of, and solutions to, air pollution.
Students follow steps to dilute a colored dye in water until the dye is one part per million. Then students consider atmospheric gases that are present in trace quantities, like ozone, and discuss how pollutants can be hazardous at very small concentrations.
Students create graphic organizers describing the four major air pollutants reported in the Air Quality Index (ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide) and then identify the pollutants with a guessing game.
