My curriculum extended over a four-month period, which is longer than I had originally planned. I began my presentation in October discussing outdoor and indoor pollution.
Students read and interpreted the pollution count on the weather page of the newspaper.
We talked about the definitions of key words. We put out petri dishes for 24 hours and after collecting them, we observed under a microscope, the particles found in the dishes. We did the deep breath exercise to experience the sensation of not getting enough air. Following this exercise, we discussed facts about the average number of times a person breathes in a day, processing two gallons of air per minute. Students did the exercise of drawing and labeling the bronchial tubes.
