PHYSICS 22 LABORATORY

This laboratory meets once a week for 12 weeks according to the schedule on the next page. There will be NO laboratories the first week of class. Hence your first laboratory meeting will be Thursday, January 19 at the time scheduled for your section. You are expected to attend all twelve laboratories and submit a written report for each. Attendance will be taken at each meeting and it is part of your responsibility to assure your attendance is recorded by your laboratory instructor. You may make up ONLY one laboratory during a makeup sessions at the end of the semester. The makeup laboratories are scheduled for April 24, 25 and 26. You may sign up for any makeup session convenient for you, but you must sign up BEFORE noon, Friday April 21. DO NOT ASK FOR EXCEPTIONS.

Bring your textbook to laboratory. The laboratory covers the same material as your lecture course. You may preview the laboratory by going to Blackboard. A schedule and other course information may be found there.

You will work in teams of two, and each team will submit one report with two cover pages. The second cover page will be separated from the report after grading and returned to one team member and the other cover page and report will be returned to the other team member. Keep these on file in case of a dispute about grades. Your laboratory report grades will be posted on the campus Blackboard system by noon each Monday following a laboratory. You should check your grades regularly. A grade cannot be disputed after it has been posted on Blackboard for two weeks.

Usually the material involved in the laboratory will be concurrent with your lecture course. However, sometimes you may be introduced to new material in the laboratory so you have some “hands-on” experience before encountering the material in lecture. Studies have shown that learning occurs when the student is puzzled and must work for understanding. At times you may be puzzled in this laboratory. If you and your partner cannot resolve the puzzle ask your laboratory instructor (who may reply with another question.)

Laboratory reports will be graded on the basis of 100.

Laboratory Report Grading Standards:

Grammar Voice, tense, spelling, references, sentence structure 20

Format Cover sheet complete, margins, appearance 10

Analysis Values extracted, percent relative errors, units,

explanation of how analysis was done 35

Data quality, completeness, plots, extra effort 15

Conclusion Summarize your measurements, values derived and their

errors. Did your measurements fit the model? 20

----

Total (each report) 100

A total of 1200 points is thus available. Missed labs receive a grade of 0. Course grades will be given according to:

TOTAL POINTS GRADE

≥ 1080 A

960 – 1079 B

840 – 959 C

720 – 839 D

<720 F

If you have a question about the grading of the lab report, bring it to me, Dr. Ralph Alexander, 204 Physics (), 341-4796 or give it to your laboratory instructor and ask him to give it to me. This must be done before the two week deadline mentioned above elapses. My office hours are MWF 9:00-10:00am and T-Th 3:00-4:00pm. You are welcome to email me to make an appointment for another time.

Resources:

1. Your primary resource is your laboratory instructor. At the first laboratory meeting he or she will provide you with his or her office hours.

2. Dr. Ralph Alexander, 204 Physics, 341-4796, My office hours are Monday, Wednesday and Friday, 9:00-10:00, and Tuesdays and Thursdays 4:00-5:00pm. I am usually in my office and you are welcome to drop in. Or to be sure I am there, email for an appointment.

Contact Persons:

1. If you have difficulty understanding your laboratory instructor’s language, contact Dr. Alexander, 204 Physics, 341-4796, or Dr. Paul Parris, chairman, Physics, 101 Physics, 341-4790, .

2. If you are unable to resolve a problem by talking with your laboratory assistant, contact Dr. Alexander, 204 Physics, 341-4796, or Dr. Paul Parris, chairman, Physics, 101 Physics, 341-4790, , or Dr. Paula Lutz, Dean, College of Arts and Sciences, 121 Fulton Hall, 341-4131,

Laboratory Report Check List:

Cover Sheet: Fill out information required. Be sure that you have a cover sheet with your name listed under “NAME” and your partner’s name in the appropriate place. If your copy does not have your name in the correct place, you will not receive credit for the lab report. There must be a cover page attached for EACH team member. Ten points will be deducted from your score for each missing item on the cover page.

Objectives: This section may be supplied, in whole or part, or you will need to supply it after you understand the purpose of the laboratory exercise.

Reading: References to your textbook relevant to this lab. Include page references. Bring your textbook to laboratory.

Introduction: A brief summary of the concepts needed, and how the measurements were performed and analyzed. This section should probably be written, at least in part, after performing the measurements and analysis.

Apparatus: List apparatus used, including any software required. There should be a schematic diagram (which may be hand drawn) of the apparatus.

Procedure: Describe how you made your measurements.

Measurements: This section (which may appear in the Procedure section) should include your measurements, often in tabular form. What is in the table should be clearly labeled (columns and rows) and the table must have a title. (Tables may be copied from Data Studio into EXCEL for some experiments, where calculations can be done and results copied into your report in WORD.) Units need to be included. Graphs may also be appropriate and should have a title and axes labeled.

Analysis: This section should describe what you did to interpret your measurements and derive some quantity, g for example. Also included should be any appropriate analysis of errors. Needed equations should be presented with a reference to your text.

Conclusions: Include a brief summary of your procedure and analysis. Comment on your error analysis. For example, does the accepted value of g lie with in the range of your derived value of g, with your estimated error?
