SCHEDULE
Laboratories will begin on July 7 , 2010 and run through August 19, 2010 . There will be 12 experiments. The purpose of this course is to teach you how to make measurements of physical quantities and how to analyze and interpret them. Working in groups of two, you will make measurements, tabulate and graph your data, evaluate uncertainties in your measurements, analyze the results of your experiments, and answer the questions given in the laboratory manual. Two of these experiments will be practical labs in which you will work alone. At least two times during the course you will change to a new lab partner.

PREPARATION FOR THE LAB SESSIONS
You will find it very helpful to prepare well, i.e. read and study the materials for the laboratories before you come to class. Being prepared before you come to your lab session will enable you to finish on time, enjoy the lab more and help you get a higher grade. All the materials to be graded (your lab report including data sheets, graphs, answers to questions) must be completed during your lab period and handed in to the instructor before you leave the lab.

The lab report consists of a data sheet in the form of an Excel spreadsheet, formula view of the Excel spreadsheet, graphs with comments and answers to questions. Write your name, your student number, lab partner's name and section number on this data sheet.

During practical labs, no outside notes, calculators or discussions with other students are allowed. After the last session of the experiment preceeding each practical lab has finished, the experiemntal write-up will be available on the course website (i.e. after experiment 5 for practical 1 and experiment 10 for practical 2). During the practical lab, you will be given a copy of the experimental write-up to use. The practical lab will be based on one or more of the experiments that you have already completed. It could consist of measuring and analyzing data, analyzing a prepared set of data and answering questions. The time limit on the practical lab will be 45 minutes.

GRADES
All labs, including practical labs will be graded by your instructor on a 20 point scale and will be handed back at the beginning of the next lab.

Your grade will be based on the total number of points during the semester.  Since the instructors for the various sections do not necessarily grade identically, the scores for a given instructor's sections will be considered as a group for grading purposes.  Each of the groups will receive approximately the same average grade in the course, so that there is no advantage to having one instructor rather than another.  Within the group, the grades will be assigned strictly in order of points achieved.  The grade will be assigned by a curve, not a "straight scale".  In the past, the average for the course was about 2.6. Please obtain from your instructor and save your graded lab reports and quizzes. You will need all of these if, at the end of the semester, you think your score wasn't correctly calculated.

MISSING LABS/MAKE-UP LABS
Make up labs are limited to attending another regularly section on a date in which the experiment is being performed and are only available for students who miss a lab for a legitimate reason. Because personally participating in each laboratory is the essential part of this course, you must be present for each session. Should you find yourself in a position where you must miss a session, you must inform your instructor beforehand, and provide an explanatory note with suitable documentation. If there is room in another section, you can make arrangements with your lab instructor to make up the lab by attending a different section. However, many of the sections are full so it may not be possible to find room in another section. In addition, arrangements to attend another section must be made with your lab instructor. If you miss a lab for an unanticipated reason, such as illness, you must notify your instructor no later than 24 hours after the missed lab and provide suitable documentation (i.e. a note from your MD). To ease the burden on students who miss a lab due to a legitimate reason, we will drop the lowest lab score of the semester before computing your grade (a practical lab can be used for this dropped lab).

PLAGIARISM OR COPYING WILL NOT BE TOLERATED
Plagiarism or copying will not be tolerated. Lab partners are expected to turn in copies of the same Excel data sheets and graphs. Answers to the questions, however, are not to be copied, word for word, from the course pack material or from another student. Also, lab partners turning in identical or slightly modified versions for the answers to questions, will BOTH receive a zero for that lab. Please review MSU's policy on Academic Integrity included below:

Academic Integrity:
The principles of truth and honesty are recognized as fundamental to a community of teachers and scholars. The University expects that both faculty and students will honor these principles and in so doing protect the validity of University grades. This means that all academic work will be done by the student to whom it is assigned, without unauthorized aid of any kind. (See General Student Regulation 1.00, Scholarship and Grades, for specific regulations.) Instructors, for their part, will exercise care in the planning and supervision of academic work, so that honest effort will be positively encouraged. If any instance of academic dishonesty is discovered by an instructor, it is his or her responsibility to take appropriate action Depending on his or her judgment of the particular case, he or she may give a failing grade to the student on the assignment or for the course. In instances where a failing grade in a course is given only for academic dishonesty, the instructor will notify the student's academic dean in writing of the circumstances. The student who receives a failing grade based on a charge of academic dishonesty may appeal a judgment made by a department, school, or a college to the University Academic Integrity Review Board. Refer to Academic Freedom for Students at Michigan State University. When, in the judgment of the academic dean, action other than, or in addition to, a failing grade is warranted, the dean will refer the case to the college- level hearing board which shall have original jurisdiction. In cases of ambiguous jurisdiction the appropriate judiciary will be randomly selected by the Assistant Provost from one of the three core colleges. Appeals from the judgment may be made to the University Academic Integrity Review Board. Refer to Academic Freedom for Students at Michigan State University. In instances of academic dishonesty where the in structor feels that action other than, or in addition to, a failing grade in the course is warranted, the instructor will report the case to his or her departmental or school chairperson and to the student’s academic dean. The dean will then refer the case to the College- level hearing board which shall have original jurisdiction Refer to Academic Freedom for Students at Michigan State University.

TARDINESS POLICY
Attendance in the lab is mandatory and there will be a penalty for arriving late to class. Two points will be removed from the Lab score for every five minutes that a student is tardy in coming to the lab. In addition, those arriving late to class will not be allowed to benefit from the work of students who arrive on time (i.e. joining a group who started the experiment on time will not be permitted). To account for the difference in clocks, you should try to arrive early to the class.

Your instructor is in charge of all aspects of laboratory procedures. Please confer with your instructor if you have a problem, since he or she can ordinarily solve most problems.

The laboratory coordinator for this course is Richard Hallstein. His office hours are Tuesday 10:30am - 11:30am in room 1253BPS. If you cannot make this office hour and would like to make an appointment send an e-mail to hallstein@pa.msu.edu. Please include a phone number and a copy of your academic schedule so he can get back to you and set up a mutually convenient time.

Communications regarding the day-to-day operations of your section should be directed to your TA NOT the lab coordinator. (ie: a missed lab, attending another section, etc.)

COMPUTERS IN PHYSICS 252

Computers will be used in all the physics undergraduate labs and they are controlled by a central server. It is your responsibility to close all applications and log-out of your computer account when you leave the laboratory.

There are four software tools you will use in the physics labs:

I. Microsoft Excel
This is a spreadsheet program which you use to record/store your data. An empty spreadsheet is available at the start of each lab. The program allows you to do ALL calculations on your data. This tool removes all repetitive calculations from the lab, so you can concentrate on graphing and interpreting your data. However, the spreadsheet does not do ALL the calculations for you. In order to start the calculations you must perform at least one of them by hand. After you enter the correct formula into the spreadsheet for that particular quantity, the program will do all the other calculations for you.

II. Kaleidagraph
This tool is a general plotting program. It takes its input from columns of data and allows you to either plot a histogram of the contents of one column and/or graph any column versus any other column. Although some of these things are possible in Excel, Kaleidagraph has a very user friendly interface for adjusting axes/labels/text/bins etc. in any of the graphs. The input for the graphs is copied/pasted from the Excel spreadsheet. Once you are satisfied with your graph (binning is correct, labels are clear, axes are labeled and have units!!), you should save the graph to your user space on the server or on a floppy disk. It can then be printed separately or copied/pasted into your final lab report.

III. Microsoft Word
Word is used as the standard wordprocessor for the lab.

IV. Graphing Calculator
This is a tool very similar to a graphics calculator, but much more flexible. It allows you to graph functions in a very convenient way and even print them out.

GENERAL INSTRUCTIONS AND HINTS:

·  Bring a flash memory stick so you can save your files as you work. There is no space on the computers to save your lab files!

· SAVE YOUR DATA OFTEN!! If something happens to your work during the lab and it is destroyed, you will have to do the lab again.

·  All the necessary computer software and spreadsheets will be on the computer when you start, so you should not have to search for items.

·  No food or drinks of any kind are allowed in the laboratories....there are NO exceptions.

HINTS ON HOW TO WRITE A GOOD LAB REPORT:

• Whenever your lab report includes a table of data from Excel, write down enough information so the reader knows where the data came from. If some of the columns include the results of a calculation performed within Excel, write down the formula next to the spreadsheet, including the values of any fixed parameters used in the formula. Also include a sample calculation showing what Excel did for one line of the spreadsheet.
• Whenever your lab report includes a graph, write down what you learned from the graph, or any conclusions you made from looking at the graph.
• If the results didn't come out as you expected, suggest why not. (Don't just attribute it to "human error"!)
