Course description: Physics 271 is the laboratory associated with Physics 270 and carries one credit. You must pass both Physics 271 and 270 in the same semester to receive credit for either; you will be required to repeat both 270 and 271 otherwise. The scores for both courses will be combined and the grade for Physics 271 will be identical to that of Physics 270, as required by the Engineering College. The labs meet for three hours a week and you will be expected to complete eight experiments and two culminating laboratory activities.
CORE: Phys270 and Phys271, taken together in the same semester, satisfy the CORE physical science laboratory requirement. Phys270 alone does not satisfy the CORE nonlaboratory science requirement.

Attendance: You should make every effort to attend your regularly scheduled lab section, but if you must miss your section please contact the appropriate TA and request to attend another section, in advance if possible. We will try to accommodate such requests if space and equipment are available. Otherwise, you must sign up to perform the experiment during the designated make-up week. It is your responsibility to deliver your write-up to the TA for your registered section and to ensure that you receive credit for all lab reports. Do not discard lab reports before final grades are posted!
Late arrival: Classes begin promptly on the hour and it is important to arrive on time to receive lab instructions and to have sufficient time to finish. If you arrive more than 10 minutes late you might not be allowed into the lab and would then have to make it up in another section or during the make-up week.

Regular labs: the 8 regular labs comprise a total of 70% of the course grade. Each of these labs will be scored as follows:
|
prelab questions |
0, 10, 20% |
|
data |
40% |
|
analysis |
25% |
| postlab questions | 15% |
Prelab questions: the prelab questions must be answered before coming to lab and will be checked at the beginning of each lab. They will graded as follows: no attempt, 0%; feeble attempt, 10%; sincere attempt, full 20% even if partially incorrect.
Data and analysis: you will work with lab partners and will share data with them. However, you will be responsible for doing your own analysis and write-up. Each person in the group will also be required to demonstrate proficiency with the spreadsheet. You will be tested on this basic skill during the lab sessions. If by the end of the second lab, you cannot demonstrate to your teaching assistant the ability to do simple tasks on the spreadsheet, your grade will be progressively reduced each week until you can. The point is: you must learn to use the spreadsheet.
Lab reports: our aim in this lab is to enhance the understanding of the experiments you perform while at the same time minimizing the amount of time spent on analysis and write-ups. This means that it is not necessary to do extensive write-ups. Overly long or padded lab reports will be penalized. Be sure to label all tables and graphs with quantities and their units. Reports must be submitted before leaving the lab.
Culminating labs: are special labs where you will be given questions about some of the labs you performed during the semester. The list of possible questions is included in the lab manual and you should review the ones for each lab after you have completed that experiment. This will make the culminating lab much easier! More questions may be handed out during the semester. The 2 culminating labs comprise a total of 30% of the course grade.
Missed lab: missing a lab and not making it up will result in failure of the course.

The following table outlines the experiment and discussion schedule. You are strongly advised to read the relevant chapter of the laboratory manual, work through all derivations, and answer the prelab questions before coming to the lab so that you understand the physical principles for each experiment and the assumptions used to relate abstract principles to practical measurements. You should also work through the error propagation for derived quantities so that you can anticipate which uncertainties are likely to determine the accuracy with which the experimental goals can be achieved. You should then be well prepared for making careful measurements and complete record keeping. If you prepare well, you should be able to complete the lab is less than the scheduled time. Inadequate preparation usually results in inefficient use of laboratory time!

Spreadsheet introduction: The first week will feature an optional review of spreadsheets in general and Excel in particular. If you are not familiar with spreadsheets, you should attend because Excel will be used to perform data analysis and prepare lab reports. If you have taken Phys261, you should already be sufficiently skilled in the use of spreadsheets but you are welcome to attend the review.
Labor Day: Students whose section meets on Monday may attend the optional review of Excel during an alternative section because the University is closed on Labor Day. Please find a Tuesday-Thursday section that is compatible with your schedule.
Be alert to announcements: Acts of God or Man may require adjustment of the lab schedule.
Making up a missed lab: If you miss a lab and cannot make it up in one of the other sections, it will be necessary to sign up for a make-up during one of the scheduled make-up periods. Failure to perform all of the labs will result in failure of the course.
