Air pollution #3 – Building the idea of pollution caused by PM (secondary students)

The aim of this activity is to help students gain an understanding of air pollution that is compatible with its scientific definitions. Specifically, it focuses on the understanding of air pollution as the presence of suspended particulate matter (PM) in the air. Students first analyse which pollutant is usually referred to by the media when describing urban air quality. Then, they carry out a learning lab activity exploring an analogy – they compare the pollution generated by an engine to what happens when a peanut is burned instead.
