Each student is expected to make an oral presentation on the subject of their choice. The topic must pertain to some aspect of clay mineralogy (either a lab project or a library referenced presentation is possible). An abstract, outline, figures and list of references should be provided to each class participant. Grade is determined as follows: Midterm exam (20%), Final exam (30%), Labs (40%), Oral presentation (10%).
