Before coming to each lab: you should read the lab manual available at the course webpage, and have a clear idea of the main goals and procedures of the lab. The instructor will not “walk through” the lab procedures in class.

Lab partners: you will rotate through the stations and change lab partners each week.

Lab reports: Laboratory reports determine your grade of this course. They are due the week after the experiment is performed, at the beginning of the class. Refer to the Guidelines for Reports and Sample Report on the course web site.

As a guide, your report should be within 2 to 5 pages, legible, concise, and at the level of professional technical writing. Copying and pasting texts, pictures, equations, and procedures from the lab manual is strongly discouraged, and may lead to a deduction in the grade. You should instead summarize in your own words what you set up to do, what you did, and then present the data, analysis, and discussion of the physics and/or techniques you have learned. All data should have proper description (e.g., the resistivity ρ), units, effective digits, and if applicable, estimation of error or uncertainty. All plots should have proper axis labels, legends, and proper choice of data points or lines. Raw data, if exceeding a reasonable amount such as hundred of points, should not be directly tabulated in the report — they should be presented in plots/graphs for example.

Copying reports from other students will be considered an Honor Code violation (the GMU Honor Code: Identical lab reports from the lab partners will result in a deduction of grades for all the reports involved.

Submission of data sheet: before leaving the lab, you should make sure you have kept a record of all your raw data, and submit a data sheet (summary of your raw data and plots) to the instructor.

Grading: Each lab report is assigned a grade 0 to 10. All labs are counted equally; no grades are dropped. The test, if scheduled, will weigh as 1.5 labs.

Make-up lab is only for students who missed a lab with a valid excuse. To be eligible for the make-up lab, a written request must be submitted to the instructor before the date of the missed lab.
