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
Skuja)
Section 0401 - Wednesday 2:00 pm – 5:50 pm (Professor
Skuja)
Other sections of this course is
taught by Professor Hoffman:
Section 0101 - Monday 2:00
pm - 5:50 pm (Professor Hoffman)
Section 0201 - Tuesday 1:00
pm - 4:50 pm (Professor Hoffman)

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 possible. Otherwise, you must make up a missed lab during
“make-up week” at the end of the semester. All labs must be completed to get a
passing grade in Physics 276.

All
experiments must be completed to pass the course.
Experiments: There are seven experiments (Lab 6 is split into two parts) as well as an introductory Lab (Experiment zero). 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. 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) Use your spreadsheet to record, plot and analyze your data in class as you collect it. Keep a complete record in the spreadsheet of the experiment including diagrams of measurement configurations actually used to obtain data, your results, and the analysis used to obtain the results.
(3) Include estimates for the uncertainties in your measurements. Include systematic errors as well as statistical errors.
(4) When something in the lab isn't making sense or isn't working raise your hand and discuss with your instructor.
(5) Do not leave class unless you have finished your data analysis, discussed your results with your instructor and turned in your spreadsheet
(6) Do not forget to turn in your complete lab report by the start of the next lab when required.
Lab Reports: You are required to submit a written report of your results for two of the experiments. 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. Both lab reports must be submitted on time not to incur a penalty. You will be deducted 5% of the maximum grade points allocated a day for each day the lab report is late. You will lose an additional letter grade for the course if you fail to submit both lab reports.
An outline of the requirements for the report is given in a separate rubic, available on the class web site.
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 40 points as follows:
·
+5 turn in spreadsheet
·
+10 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)
·
+5 all errors on results of fits,
calculations, etc done (partial credit possible)
·
+5
spreadsheet is neat and well labeled.
General Comments on Spreadsheets and Lab reports: Finishing and submitting a complete spreadsheet as well as
a lab report when required 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 spreadsheet or 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 spreadsheet or report, or let someone else copy yours. That is cheating
and is strictly forbidden. It is also very self-defeating since part of your
grade will come from a practical test of your knowledge of lab content and
procedure. The right way to proceed is to prepare your spreadsheet before class
and write up your spreadsheet or 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: Part of a class
meeting will 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. 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.
Talks: Each student will give a 10 minute oral presentation on one of the Experiments. The report should be accompanied by electronic slides written in Power Point format (or equivalent) that is prepared in advance. Presentations should be on one of the Experiments from II to VII.
Lab Exam: A Practical Lab Exam will be administered at the last session of classes. It
will cover the material of the experiments. Students will be expected to be able to repeat some of the experimental work and procedures they did in class as well as be able to explain the physics underlying the experiments. Knowledge of the workings of the instruments used in the lab may also be tested. If you fail to take the final exam you will be deducted an additional letter grade for the course.
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.
