Set up procedure to take the air pollution samples. We decided to take samples at two locations, one site in the hills away from downtown, and another site at our elementary school. Take a series of samples over a week or two. Try to take samples under different weather conditions. Keep track of temperature, wind speed and direction, cloud cover, precipitation.
Students look at the data samples and discuss what they see.
Write student observations on the board or chart paper. Have students keep track of their observations and ideas in their folders or journals. Using their observations, have students generate other questions from their observations. This can lead to a discussion of the sources of pollution in Fairbanks. Students do a fast write of what they have learned.
