LABORATORY
REQUIREMENTS
SCHEDULE
Laboratories will begin on Wed (remember Wed==Monday for this
first week) Aug 30, 2017 and run through
PREPARATION FOR THE LAB SESSIONS
You will find it very helpful to
prepare ( 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. For most of the labs, there will be a homework
assignment on LON-CAPA that must be completed before 8 AM
Monday the week of the lab. You should have been automatically
enrolled in LON-CAPA. For a few labs, there may instead be a
5-minute quiz given at the beginning of the lab period.
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; there will be ABSOLUTELY NO EXCEPTIONS. The lab report consists of a cover sheet (that can be downloaded here) plus any spreadsheets (both data and formula views from Excel) and plots requested. Please print out and fill in the cover sheet each week BEFORE coming to lab. Sample calculations are required for each formula that was entered into your spreadsheet to verify it was done correctly. At the bottom of any graph must be a statement of what is being plotted, and if a straight line fit is done, a quote of its parameters (e.g. slope and its uncertainty), plus a comment on what the results of the graph indicate. In addition, any worksheets containing questions to be answered should be turned in with your data.
During practical labs, no outside notes, use of the Internet, calculators or discussions with other students are allowed. Students making use of unauthorized help for the practical will receive a 0.0 for that practical. Each student will perform one of the experiments that was done earlier in the semester by him or herself. The experimental write-up for the practical will be posted on the course website approximately a week before the practical. 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/or 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. The points will be distributed
roughly as follows: homework/quiz (4 pts), acquisition of data
(4 pts), graphs and calculations (6 pts), and answers to
questions (6 pts).
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". Please obtain from your instructor and save your graded lab reports. You will need all of these if, at the end of the semester, you think your score wasn't correctly calculated.
PLAGIARISM, COPYING AND CHEATING WILL NOT
BE TOLERATED
Lab partners are expected to turn in copies of the same Excel
data sheets and graphsBUT answers to the questions and
comments on graphs are not to be the same. Lab partners
turning in identical answers (or slightly modified versions)
will BOTH receive a penalty grade of zero for that lab. Any
plagiarism, copying or cheating will result in a penalty grade
of zero for the lab and the submission of an Academic
Dishonesty Report for placement in the student's permanent
record. MSU's policy on Academic Integrity is part of this
syllabus, please review it at
https://www.msu.edu/~ombud/academic-integrity/index.html.
Penalty grades will not be used as a dropped lab.
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 (i.e. 0-5 minutes late two points are
deducted, 5-10 minutes late four points are deducted,...). 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 Joey Huston. His office hours are Monday 11AM-noon in room 3230BPS. If you cannot make this office hour and would like to make an appointment send an e-mail to huston@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. (i.e.: a missed lab, attending another section, etc.)
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, most of the
sections are typically full so it may not be possible to find
room in another section. 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 Patient
Instructions form 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).
Only one lab will be dropped. The dropped lab accounts for all
unforeseen occurrences such as, illnesses, accidents, family
emergencies, etc. No make ups will be given for students not
on campus at the start of the session. In addition, students
are expected to be available to attend all labs for the
duration of this accelerated course. Missing labs for planned
events like vacations or weddings are not legitamte reasons
for missing labs. Students with such obligations should not
enroll in this class.
PERSONS WITH DISABILITIES
Students with disabilities and/or any other special needs
should identify themselves to the instructor during the first
week of class. You must provide a copy (or an email) of your
VISA from the RCPD office to both your TA and the lab
coordinator by the end of the first week of class. Individual
arrangements will be made to accommodate those needs on a
case-by-case basis. It may not be possible to honor VISAs that
are presented to the instructor after the first week of class.
CONCERNS/PROBLEMS
Your lab instructor (the TA) is in charge of all aspects of
laboratory procedures. Please confer with him/her if you have
a problem, since they can ordinarily solve most of them.
Communications regarding the day-to-day operations, such as a
missed lab should be directed to your TA, NOT
the lab coordinator. Your TA will provide you with his/her
email address and office hours at the beginning of the
semester. If you have concerns about a score on a lab you must
make an appointment to meet with your lab instructor outside
of lab time. TAs will not respond to questions concerning
individual lab grades while a lab section is in session.
If there are issues that your TA cannot address, you should contact the lab coordinator Joey Huston. Please set up an appointment by email to huston@msu.edu
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.
Your lab report must be completed during the lab period and handed in to the instructor before you leave. More details and instructions regarding the components of a lab report are listed in Appendix C of your lab manual. In brief, the report should include the following components in this order:
In your report, explain how you identified and tried to solve problems in the experiment. If your data do not correspond to the anticipated results, you should explain what went wrong. "Human error" does not count as an explanation, be more specific if your results are different from what you expected. Your grade will depend on how clear, accurate and brief you are. Copying of text from others, the internet, old lab reports, the lab manual etc. is expressly forbidden. Lab reports that show evidence of plagiarism will receive a penalty grade of 0.
