Experiments: Each student is expected to successfully complete all 10 experiments.

Lab Reports: Each laboratory report consists of 3 parts: pre-lab questions, experiment’s report sheets and post-lab questions. Each lab is total of 15 points.

Pre-lab Questions: The questions preceding each experiment are to be answered before coming to lab and submitted to the TA at the beginning of each lab period.

Report sheets and Post-lab Questions: The report sheets, which include experimental data and calculations as well as answers to the post-lab questions, should be submitted at the beginning of the next lab period. All questions should be answered unless otherwise indicated by your instructor.

Late report policy: If lab reports are turned in 1 day late or within the same week of scheduled deadlines, students only earn 90% of their original lab grade. If lab reports are turned in one week late, students only earn 50% of their original lab grade. After one week, no lab reports will be accepted and students will get a zero for that lab report.

Lab Quizzes: Five Lab Quizzes will be posted in WesternOnline under “Assessment”. Each quiz is 10 points. You have two attempts for each lab quiz, and the highest score will be counted. If students miss the deadline for submitting their lab quiz on WesternOnline, no quiz makeup will be offered.

Lab Makeup: Only one lab makeup for the excused absence will be allowed. The makeup lab is scheduled in Week 15 (04/26-04/28).

* You must earn at least 60% (120 points) of the maximum points attainable (200) In the lab part or you automatically fail the course. * If a student misses three labs including both excused and non-excused absences, the student will fail the course immediately. Lab Grading System: 10 Labs (15 points each) = 150 points 5 Lab Quizzes (10 points each) = 50 points Total: 200 points

Attendance: Each student is expected to attend and complete each scheduled laboratory. Excused absences will be allowed due to illness and certain other mitigating circumstances. In such cases, it is the student’s responsibility to contact the instructor. Additionally, it is the student’s responsibility to ensure that the instructor is informed of his or her presence, so that he or she will not be marked absent from the assigned laboratory.

Personal protective eye wear is required. The student must purchase safety goggles and lab manual. Students are not allowed to participate lab if they don’t have safety goggles. Students are expected to wear clothing that completely covers the feet and legs in lab. (Sandals, skirts, dresses and shorts are not allowed in lab).
