Laboratory work is an essential part of an 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:
- use standard instruments such as multimeters and oscilloscopes effectively
- make reliable measurements, with no fear
- recognize and troubleshoot errant circuits
- present results more clearly through graphs and tables
- analyze data to reveal underlying relationships
- use computers for curve fitting and preparing graphs
- estimate experimental uncertainties and understand their consequences
- report reliable calculations with the appropriate number of significant figures
- keep an accurate and complete laboratory notebook
Finally, this laboratory experience should provide you with
the opportunity to develop a deeper understanding of some
of the concepts of introductory electricity and electronics.

Guidelines:
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 5:00pm Monday.
The lab exercise instructions 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 four students. Lab reports should be submitted
in whatever format is recommended by the lab instructor.
The drop box for completed PHYS245 laboratory reports is Box #21.
This is located in the array of drop boxes located near the Sharp Lab 131, the
auditorium.

Schedule:
Laboratory sections begin meeting regularly during the second week of classes.
Laboratory schedule will be completed as the semester progresses.
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? |
