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 Physics Building. Roughly three hours of this time will be spent working on the lab and one hour in discussion. At the end of each lab period, you must turn in a spreadsheet with your data and analysis. A complete written lab report is due one week later, at the start of the next week's lab.


Laboratory Location - Room 3120 Physics Building


Lab meeting times: Section 0101  - Monday 2:00 pm - 5:50 pm (Professor Paglione)

                                  Section 0201  - Tuesday 2:00 pm - 5:50 pm (Professor Paglione)

                                  Section 0301  - Friday 12:00 pm - 3:50 pm (Professor Orozco)


Arriving late to class: Classes at Maryland begin right on the hour. You must arrive on time so that you can get instructions for the lab and have time to finish. If you are more than 10 minutes late, you may not be allowed into the lab and will have to make it up during another section.


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.

Office Hours: I’m happy to meet with you!  Contact me with an email and we’ll find a time that is convenient for both of us.  Meeting with your instructor to discuss your work outside of the classroom is one of the best ways to get the most out of your educational experience.



Teaching Assistant: TBA


Required Texts:  

- "Physics 276 Laboratory Manual", Fall 2004 Edition, Department of Physics, University of Maryland, Wiley Custom Services.


Recommended Texts:

- "An Introduction to Error Analysis: The Study of Uncertainties in Physical Measurement", John R. Taylor (University Science Books, 1997, ISBN 0-935702-75-X).

- The standard Physics 272 textbook or any equivalent text, will be useful for explaining the basic physics in the course.


Grading:        35% in-class spreadsheet

50 %  Lab Reports

                        15 %  Final Practical Exam


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  next lab. 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: 

·            +5: turn in spreadsheet

·            +2 all data taken

·            +2 errors assigned to all measured numbers (no partial credit)

·            +7 all fits, calculations based on measured numbers, etc done (partial credit possible)

·            +2 all errors on results of fits, calculations, etc done (partial credit possible)

·            +2 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. 


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 University of Maryland, College Park has a nationally recognized Code of Academic Integrity, administered by the Student Honor Council. This Code sets standards for academic integrity at Maryland for all undergraduate students.  As a student, you are responsible for upholding the highest standards of academic integrity in this course and should be aware of the consequences of cheating, fabrication, facilitation, and plagiarism. For more information on the Code of Academic Integrity or the Student Honor Council, please visit



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.
