Lewicki and Jennifer Jourdan, LAD Custom Publishing, 2011. Welcome to Physics 21900 laboratory. This semester, you will explore the fundamental
concepts of electricity and magnetism by performing experiments, collecting data and
analyzing your results.
Labs meet in Physics Building (PHYS) Room 150. The Lab manual (Physics 21900 &
22100 Laboratory Manual, 2011/2012, Andrzej (Andrew) Lewicki and Jennifer Jourdan,
LAD Custom Publishing, 2011) is available from local bookstores. Do not buy any previous
editions of the lab manual. Please note that both Physics 21900 and Physics 22100
courses use the same lab manual and have the same lab curriculum.
Students who completed Physics 21900 lab during the last two years may claim the
previous credit for the lab. The minimum requirement for the credit transfer is to have all
experiments completed and have the number of points for the lab equal to at least 75% of the
maximum. To transfer lab points from the previous semester, go to see the lab coordinator
with your Purdue ID no later than at the end of the second week of classes.
Lab reports are usually due at the beginning of the next experiment. For the exact dates,
see the lab schedule at the end of this syllabus.
Always bring a calculator with you to the lab. Do NOT bring drinks or food to the lab!
The help center for Physics 21900 is located in Room 11A of the Physics Building. The
help center schedule is available at the following address:
1 Lab Syllabus Purdue University - Physics 21900 Fall 2011 Additional information about the course can be found on the WWW at:
http://www.physics.purdue.edu/phys221/ Lab procedures:
Before coming to lab, you must answer all prelaboratory questions scheduled for that
week. These questions are closely related to the activities and measurements you will do in
lab. The prelaboratory questions typically require 30 minutes of effort. The prelaboratory
questions are your individual work, so everyone is expected to complete them. The
prelaboratory questions must be answered on-line (except of make-ups) using the
Computerized Homework in Physics (CHIP). CHIP is accessible to any computer running
popular web browser software, e.g., Firefox, Safari or Internet Explorer.
All lab scores including points for prelaboratory questions (prelabs) and points for lab
reports will be stored on CHIP. The prelabs of CHIP are due before the deadlines, which
are set exactly at 10 minutes before the beginning of the scheduled lab time. For
instance, if the lab is scheduled on Wednesday at 11:30 AM, the deadline for prelabs is at
11:20 AM on that day. After deadlines, CHIP would not assign any points for the prelabs
(no credit for late prelabs). Physics 21900 students will be able to access their gradebooks
(using CHIP) and check the latest scores. You will find more information about accessing
and using CHIP on a separate handout available in the lab or from Undergrad Office in room
During the two-hour laboratory period, you will observe phenomena, manipulate the lab
apparatus, collect data and ask questions. Be on time for the lab. Remember to sign the lab
attendance list! Your lab TA will briefly review the theory behind the experiment and
describe the lab equipment to be used. Before leaving the laboratory room, make sure
that your TA has initialed your data sheets. The minimum penalty for the lab reports
without TA’s initials is 2 points. TA may even refuse to accept lab reports without initials.
In the Physics 21900 lab, you will work with a lab partner. All experimental data must
be written in ink on your data sheets. TAs have been instructed not to initial data sheets
written in pencil. In all data sheets, you will find a pair of parentheses with an empty space
in between them: (
). You are required to write appropriate unit in that space, e.g., ( Ω
). Results without units are not complete!
During the week that follows each lab experiment, you and your partner will prepare a
laboratory report, that includes your initialed data sheets, calculations, graphs (if required),
cover sheet and the Analysis section. In that section, you should briefly describe the
2 Lab Syllabus Purdue University - Physics 21900 Fall 2011 observed phenomena. You should also explain how the results were calculated from the raw
data and what are the most important results of your experiments. Discuss sources of
experimental error and their relative influence on your results. The lab report typically
requires 1-2 hours of effort. The requirements for each lab report are clearly listed in the
Group lab reports are allowed (but not required) this semester. It means that only one
lab report for you and your partner is required. Obviously, the same credit will be assigned
to lab partners. However, if a lab report is not ready on time, the penalty will apply to
both students, regardless of who caused the delay. Remember to attach to your group lab
report separate cover sheets for all lab partners. The cover sheets are located at the end of
the lab manual. If you prefer to submit individual lab reports, you are always allowed to do
that. Just tell your lab TA about your decision. The prelaboratory questions must be
completed and submitted individually. The attendance will be taken at each experiment.
Please, make sure to put your signature on the attendance list.
The lab reports from the lab make-ups must be submitted as individual reports (no group
lab reports for make-ups).
Each lab is worth up to 14 points (including prelabs). Therefore, the maximum number
of points for the lab portion of Physics 21900 course is equal to: 10 labs*14 = 140 points.
Since the lab contribution to the total grade is 200 points, the final score will be
multiplied by 1.4286 to get 200 points (140*1.4286 = 200).
Since the grading level may slightly vary between TAs, it is possible that the final lab
grade will be normalized to have the same average grade for all laboratory TAs. Lab points
are not converted into A, B, C, ... grades. At the end of the semester, the sum of your points
earned for Physics 21900 (lab + recitations + exams) will be converted into one final letter
If you have missed an experiment for a valid reason (e.g., illness):
• Give a written documentation to your lab TA during the next lab or bring it to his
office and ask permission to make-up the missed lab.
• If you have not turned in the report from the previous lab, turn it in during the first
day after your absence to the drop slot located below mailboxes between rooms
PHYS 146 and PHYS 150 (make sure that your lab TA’s name is written clearly on
the cover page of your lab report). 3 Lab Syllabus Purdue University - Physics 21900 Fall 2011 • Prelabs for the make-up labs must be submitted on paper during the make-up session
(CHIP is not set up to handle make-ups). •
• Your TA will set the due dates for make-up lab reports.
If you have more questions about make-ups, please ask the lab coordinator. Subtracting 1 point per school day will penalize late lab reports. Even if your lab
report is very late, (i.e., zero points for the lab report due to the penalty) you would receive
points for the prelaboratory questions and the lab would be recorded as completed.
Students are not allowed to make up late lab reports or to make up more than one
experiment during the scheduled lab make-up time. Re-doing labs is not possible. Make-ups
are only for those who missed labs for a legitimate reason and got TA’s permission to makeup labs. Prelabs for the make-up labs must be submitted on paper (CHIP is not set up to
You may not copy answers, lab reports, use “files”, or allow your answers to be copied,
by any other students (except of your lab partner). Any violation of the above standards will
subject the offender to penalties allowed by the Purdue University. If you wonder whether a
course of action violates this policy, simply ask in advance. Any attempt to forge data (e.g.,
copying data from previous semesters or from other students) or to forge your TA’s initials
will be penalized!
In a case of a long illness, (e.g., two or more weeks in a hospital) you need to get
permission from the lab coordinator to make up the missed labs.
If you have any questions concerning the lab policies, please ask the lab coordinator.
Keep all graded lab reports until the end of semester.
After 5:00 PM on December 12, 2011 we will not accept any lab reports (no
exceptions)! 4 Lab Syllabus Purdue University - Physics 21900 Fall 2011 Physics 21900 Laboratory - Fall 2011
