Course grades will be assigned as follows: 90 - 100% A, 80 - 90% B, 70 - 80% C, 60 - 70% D, below 60% F. These ranges include + and - grades.

Exams consist of short answer and essay-type questions. Some calculation-based problems will be included. Please note that programmable calculators may not be used on quizzes and exams. The three exams are scheduled for the following dates:

Exam 1: Wednesday, February 14

Exam 2: Wednesday, March 28

Exam 3: Thursday, April 26 at 1:00 pm

Quizzes will be given each week. They are intended to help you assess your progress and to alert you to any "trouble spots" before you take an exam. The lowest quiz grade will be dropped. Quiz dates: January 17, 24, 31; February 7, 21; March 7, 14, 21; April 4, 11, 18.

Homework: Homework will be assigned regularly but will not be collected. Questions on the weekly quizzes will come from the homework. You can check you answers to the homework problems on the class Moodle site: Go to moodle.lycoming.edu, login using your Novell password, choose CHEM100. You will be prompted for a password (enrollment key). It is "chem100".

Writing Assignments: There will be three brief writing assignments during the course of the semester. More information will be provided in class (25 points each).

Laboratory: Labs are intended to enhance and illustrate the concepts we discuss in class. Each lab will have a response sheet that will be completed before leaving the laboratory. Response sheets are graded on a 10-point scale. There are thirteen labs, twelve of which will count towards the final grade (the lowest lab grade is dropped). A 3-point bonus will be given to students who complete all thirteen labs.

Lab Safety: Unsafe behavior in the lab will not be tolerated and violations will be penalized. Repeated violations during a class may result in a zero for that lab. Safety glasses must be worn in the laboratory at all times. Keep in mind that lab safety also includes laboratory hygiene. In the event that common areas are left dirty, points may be deducted from the entire section's lab grade. If you have any questions regarding lab safety, please ask.

Lecture: Regular attendance at lecture is expected. Students with perfect attendance will receive a 5 point bonus at the end of the semester. Students with more than three absences (for any reason) will have their grade reduced by 5 points.

Quizzes, Exams and Laboratory Meetings: Attendance is mandatory. Generally, make-ups are not permitted. Exceptions may be granted if I am notified prior to the absence and there are extenuating circumstances -- usually a case of medical or family emergency that must be documented (note from doctor, notification from Dean). Missing an exam or quiz without making arrangements with me prior to the absence will result in a grade of zero for the exam or quiz.

Labs cannot be made-up.

**Be aware that in accordance with the College's policy on academic honesty, any work you submit must be your own. Any instances of plagiarism will be penalized severely.
