Laboratory work is an essential part of the introductory physics course. It will likely play an important role in your career as scientist or engineer as well. Time spent in the laboratory, developing skill and experience in making good measurements, is a critical part of your training. Our laboratory schedule presents twelve laboratory exercises that have been selected to develop further your ability to:

|Sec. 10||Sec. 12|

|7:00 - 9:00|
Satisfactory laboratory work is required to receive a passing grade for this course. Attendance is mandatory; attendance at a section different from your normally scheduled one may be arranged beforehand with permission of the lab instructor. The grading schedule for late reports and the makeup policy for missed labs will be announced by the lab instructor. Lab reports are due by noon Monday. [added 9/29] The lowest lab grade will be dropped; this can be used to accomodate one missing lab assignment.
The lab manual should be studied before coming to the lab meeting. A short discussion will be given at the beginning of each lab to orient each student to the equipment and instructor's expectations. Generally the lab exercises will be performed by teams of either two or four students. Lab reports should be submitted in whatever format and notebook is recommended by the lab instructor.
The drop box for completed PHYS345 laboratory reports is Box #2. This is located in the array of drop boxes located near the Sharp Lab 131, the auditorium.

A Closing Thought on Grading of Laboratory Notebooks:
|Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist. What else are the grades based on? Why else would people pay fortunes for some things and throw others in the trash pile? Obviously some things are better than others . . . but what's the "betterness"? . . . So round and round you go, spinning mental wheels and nowhere finding anyplace to get traction. What the hell is Quality? What is it?|
