COURSE POLICIES
Exams: There will be two mid-term exams held during regular class time on October 10 and November 14. The final exam will be taken during the exam period and will mostly cover material from the last unit with some cumulative questions.

Labs: Labs will provide us with an opportunity for detailed examination of the plants discussed in class. Note that you do not have to turn in a lab report each week. However, you will be tested on the material covered in lab during the lab practical to be held during lab time on December 7. Therefore, it is to your benefit to keep a lab notebook containing a clear set of notes and well-labeled drawings.

Paper Discussions: These assignments are designed to provide you with experience in reading, thinking about, and discussing scientific literature. Nearly every Thursday, we will take 20 or 30 minutes at the end of class to talk over a primary research paper or review article. One student will be assigned to lead and guide the discussion, making sure that the major points are covered. However, each student is expected to contribute her own ideas. Questions to bear in mind include: what was the goal of the article or research? how was the work done? what new findings are reported? how do the results fit into what is already known? are there any weak points to the paper or the research?

Herbarium Collection: During the course of the semester you will assemble an herbarium by identifying, pressing, and mounting plant specimens. Additional information about this assignment will be provided during lab.

SEM Poster: The scanning electron microscope is an excellent tool for investigating evolutionary trends in the plant kingdom. Selecting one of the major plant phyla, each student will use the SEM to examine morphological traits in a representative species. The information and images you obtain will be presented in the form of a poster.
