Materials: Students must obtain a laboratory coat to be worn during each session. Students will be assigned a microscope, equipment drawer, and seat number. Students are responsible for the condition of their assigned microscopes and drawers.

Rules: Follow the safeguards listed in the Laboratory Protocol on pages ix - xi of the laboratory manual. A handout describing how to aseptically handle bacterial cultures will be distributed. These procedures are necessary to prevent the contamination of students as well as cultures. Attendance is mandatory for each laboratory session. Anyone who misses a laboratory for a non-verifiable reason will receive a grade of zero for any missed work. Three or more unexcused absences from laboratory will result in a grade of F for the course. Legitimately missed sessions will be made up at a time convenient to the instructor and student.

Grades: Laboratory grades will be determined as follows:

Laboratory Performance 15%

Unknown #1 25%

Unknown #2 30%

Final Exam 30%

Attendance, homework, and technique will determine the laboratory performance grade. The final exam will be a comprehensive multiple-choice exam given during the final exam week. The plus/minus grading system will not be used.

The Science Division strictly enforces the University policy on academic integrity as stated in the Student Handbook. Please read this section of the Student Handbook.
