Ch 473 - The Chemistry Behind the
Environmental Issues (Winter 2009)

Antarctic Ozone Hole, August 2006
(http://ozonewatch.gsfc.nasa.gov)

A survey of the chemistry behind environmental issues in Oregon and in the World. The major issues covered are Ozone Layer Depletion, Climate Change, Toxic Chemicals and Heavy Metals, and Air and Water Pollution. On a more local level we will investigate recent research on the decline of amphibians, the health of the Willamette River, progress on cleaning up Portland Harbor, and herbicide and pesticide use in the Willamette Valley.

Exam Policies

There are no make-up exams except for University sanctioned events, in which case please see me a week in advance for an alternative testing time. In the event of an unexpected emergency -

Midterms: Emergencies must be communicated through the Office of Student Affairs (838-8221) - they can broadcast it to all your professors. There must be some form of proof for the emergency, e.g. note from Student Health Center. If these two steps are taken, then there are two options for replacing the midterm score:

(1) If the exam hasn't been handed back to the class yet, then arrange a make-up time with me.

(2) If the exam has already been returned to the class, then I will replace the missing hour exam score by taking 30% of the percentage you receive on the final exam (since it is a 150 pt exam) and 70% of the other midterm score. This option can obviously only be used once.

Final exam: University policy states that the final exam time will not be moved for any reason, unless you have three finals in one day - you have the right to move one!

If you miss the final due to an unexpected emergency, and again communicate this through the Office of Student Affairs and provide proof of the emergency, then I won't give a makeup, but an incomplete instead. See the Incompletes section next for details.

Incompletes Incompletes are given under special circumstances such as medical reasons, family emergencies, etc. In order to receive an incomplete, the University requires you to sign a contract with me outlining the steps you must take to finish the course. Usually this means there will be a time deadline for completion of the course before your grade reverts to an "F".
Grading
200 pts (2) 100 pt Midterms (Wed, Feb 4 and Wed, Mar 4)
150 pts comprehensive final (Mon, Mar 16, 4-6 PM)
50 pts homework
400 pts total
Students with Disabilities

It is your right to request special accommodations under the Americans with Disabilities Act. For questions, call the Office for Disability Services at (503) 838-8250 V/TTY, or email them at ods@wou.edu.

Academic Dishonesty

The Code of Student Responsibility defines cheating as "intentional use, or attempted use of artifice, deception, fraud, and/or misrepresentation of one's academic work". For this class, which involves taking exams, quizzes, and perform labs, cheating is usually but not limited to talking or writing to other students, using crib sheets (prepared notes), or looking at another student's paper. The penalty for cheating will be a zero grade for the test or quiz or assignment in question.

Students have the right to appeal this action as described in the Code of Student Responsibility
