ORGANIZATION OF THE COURSE:
This is a three-credit lecture course.  Much of the material will be presented as lectures, but some class time will be used for discussion and working in small groups to solve problems or investigate geochemical phenomena through hands-on activities.  Each student is expected to attend class, read the assigned pages of the main textbook and the supplementary readings (outside of class time), and complete all of the assessment materials (homework, tests, etc).

COURSE OBJECTIVES:  In this course you should:
_Learn to apply chemical techniques to geologic problems.
_Understand the formation and distribution of the elements in the solar system.
_Understand the importance of thermodynamics (what can happen) and kinetics (how fast
   something will happen) in geologic processes.
_Become familiar with the most common chemical methods and techniques used to interpret
       geologic situations.

Evaluation

ASSESSMENT MATERIALS:
Your grade for this course will be based on three exams, eight problem sets, and class participation, including completion of fourteen in-class activities (about one per week).  When calculating your final grade, I will “drop” the lowest problem set score and the lowest two in-class activities.

Exams:  Exams will consist of short essay questions and problems similar to those on the problem sets.    They will not be strictly comprehensive, but you will need to build on what you learn throughout the course.

Problem Sets:  Problem sets will consist of up to five questions (most will be similar to "word problems") related to the lecture material.  Doing these problems will help you understand and learn to apply the concepts presented in class; this will also help you prepare for the exams.

GRADES:

Exam I 100
Exam II 100
Final Exam
110
Problem Sets (8)
200 (25 each)
Class participation (14)
140 (10 each)
, 650 points total

All course requirements must be completed to pass the course.  The grading scale is as follows:
A 100-90%;     B 89-80%;    C 79-70%;      D 69-60%;     F 59% and lower.

Labs and other assignments must be handed in on time.  For unusual circumstances, exceptions may be made but only if you make specific arrangements with me in advance. 
           
If you miss an exam, you may take a comprehensive substitute exam on November 29.
           
Incomplete grades will be given only in accordance with University policies as published in the catalog.
           
Drop date is Friday, November 11

EXPECTATIONS:
My expectations for students in my classes are pretty standard.  Basically they are the same as outlined in the list of guidelines from the Sociology Home Page at NEIU (http://orion.neiu.edu/~sociolgy/guidelines.html)

Graduate students: Additional course requirements for graduate students taking the course for graduate credit are as follows:

1. Graduate students will be assigned advanced versions of the problem sets.  The graduate student problem sets will cover the same material but will be more in-depth and will require a higher degree of sophisticated problem-solving abilities than the undergraduate problem sets.  Additional reading materials that provide more in-depth coverage of class topics will be made available for graduate students.

2.  In place of problem sets #4 and #5, graduate students will have a special assignment related to radiometric dating.

3. Exams for graduate students will contain higher order questions reflecting the more advanced material worked out in the problem sets.
