There will be a number of extra credit opportunities during the quarter. Some will be in the form of extra credit questions on quizzes, homework assignments and exams, others will be based on attending a seminar related to air pollution, and writing a short paragraph or two describing what the seminar was about. We will post dates of some seminars you might find interesting. Another opportunity is finding a recent article in the popular press (newspaper article) related to air pollution science, regulation, or health effects. The students will write a short paragraph or two on the article. Each student can complete a maximum of two (2) seminar or article extra credit activites per quarter.
