About the course:
Physics 276 is the third class in the Physics 174 - Physics 275 - Physics 276
introductory Physics laboratory sequence. It is intended primarily for physics
majors, but with permission is open to all science and engineering students.
The experiments involve phenomena in electricity and magnetism, including ac
and dc electrical circuits and electromagnetic fields. A major component of
this course is to see that you develop skills in record keeping and scientific
writing. In addition, the experiments are constructed to improve your
understanding of data analysis and error analysis, beyond what you have already
learned in Physics 174 and 275. The Lab meets for four hours each week in Room
3120 of the
Laboratory Location - Room 3120
Lab meeting times:
Section 0301 - Thursday 2:00 pm – 5:50 pm (Professor
Jawahery)
Other sections of this course are taught by professor Ellis:

Making up missed Labs:
You should make every effort not to miss your regularly scheduled lab. If you
miss your regular lab section, you must
make arrangements with your instructor to make it up before your next lab. If you
do not, your final grade will be lowered by 10% per week.

Practical Exam
All
experiments must be completed to pass the course.
Experiments: There are seven experiments (Lab 6 is split into two parts). Much of your in-class work will be carried out in Excel spreadsheets and you will need to turn in a copy of your spreadsheet at the end of each lab period. Some experiments require you to work with a lab partner, and for these experiments you will need to identify your lab partner on your submissions. We will use the web to collect lab reports and post grades.
Tips for Doing Well:
(1) Read the lab manual carefully before you go to the lab and attempt an experiment.
(2) During class, keep a complete record in your lab notebook of the experiment including diagrams of measurement configurations actually used to obtain data, your results, and the analysis used to obtain the results.
(3) Use your spreadsheet to record, plot and analyze your data in class as you collect it.
(4) Include estimates for the uncertainties in your measurements. Include systematic errors as well as statistical errors.
(5) When something in the lab isn't making sense or isn't working raise your hand and discuss with your instructor.
(6) Do not leave class unless you have finished your data analysis, discussed your results with your instructor and turned in your spreadsheet
(7) Do not forget to turn in your complete lab report by the start of the next lab.
Lab Reports: You are required to submit a written report of your results for each experiment. The reports will be submitted electronically and will be due at the start of lab the following week. Your lab report should be submitted as an MS Word or PDF file, complete with data and figures. An outline of the requirements for the report is given in a separate rubic, available on the class web site. If you had a lab partner for the experiment, you must identify your lab partner on your report.
In-class Spreadsheets: You are required to submit the spreadsheet you create in
class before leaving class. The in-class
spreadsheets will be graded out of 20 points as follows:
·
+10: turn in
spreadsheet
·
+5 all data taken
·
+5 errors assigned to all measured numbers (no partial
credit)
·
+10 all fits, calculations based on
measured numbers, etc done (partial credit possible)
·
+5all errors on results of fits, calculations, etc done (partial
credit possible)
·
+5
spreadsheet neat and well-labeled.
General Comments on Lab reports: Finishing all the lab reports is very important. If you
can't completely finish a lab, it is still important to turn in what you do
have. When you are working on your report, feel free to discuss among
yourselves to try to figure out what is going on. By all means get together in
small groups and discuss. However, do not use these discussions as an excuse to
copy someone else's report, or let someone else copy yours. That is cheating
and is strictly forbidden. It is also very self-defeating since the other part
of your grade will come from tests. The right way to proceed is to first work
through all the analysis and write up your report by yourself. With this
preparation you can then discuss intelligently with your colleagues and see if
you have missed something essential. Of course, you can always ask one of your
instructors.
Late Reports: Late lab reports will be assessed a penalty of 5% per day. A missing lab report will cost one letter grade for the course. Missing a lab entirely, and not making it up will result in failure in the course.
Discussions: Some class
meetings will mainly be devoted to discussions of the physics and data analysis
for the experiments. Participation in these sessions is just as important as
the experiments themselves. Attendance is mandatory
and you will often be graded on a spreadsheet you will complete during these
classes. However, this is not a lecture course, and the main way that you will
learn experimental physics is to by doing and discussing, rather than
just discussing.
Academic Integrity - The
In case of Bad weather: Winter in the Washington Metro area can bring large snowstorms that make travel dangerous. Should this happen and the University is closed as a result during a scheduled lab, class will be cancelled, and we will most likely reschedule the lab for the following week. Closing is announced over local radio and TV as well as on the University’s homepage.
