Cheating will result in a zero for the
assignment. Any instance of
cheating will be reported to the Department Chair and the Dean. To prevent plagiarism you must submit
an electronic copy of your introduction/reports to http://www.turnitin.com
as an MS Word or pdf file prior to turning the paper
copy in to your TA. Scanned documents will not be
accepted by Turnitin.com.
Your written introductions or reports will be compared to an extensive database
of reports from previous semesters, as well as the web and scientific journals.
You can add figures and schemes to the paper copy after the electronic search. If you are a new turnitin
user, then you will need to setup a student profile prior to joining the class.
The class ID and password will depend on your section, which are listed in the

TA Evaluations will be based on the opinions of
the TA in consultation with the instructor. Important things we will consider
include safety, general preparedness, laboratory technique, cleanliness,
laboratory notebooks, product purity, and knowledge of the procedures and
theory. The TA's will evaluate
each student several times during the course of the semester. TA's will warn students of significant
deficiencies in their performance so that they may improve during the
semester. However, the TA
evaluation grades will be kept confidential and may be used at the end of the
semester to help students that demonstrate significant improvement and/or
excellent technique over the course of the semester.
Product Evaluations will be
based on the quantity and quality of the recovered product. It is more important to have a pure
product than a high yield.
Products should be placed in clearly labeled screwcap
vials with the following information:
1) Date; 2) Your Name; 3) TA's Name; 4) Product Name;
and 5) Yield in grams. Any omitted
information will result in a zero.
Quizzes will be given during most
laboratory periods after a brief lecture by the TA, and before the experiment
begins. Questions will be based on
the prelab readings, weekly lectures, and practical
knowledge gained from previous laboratory experience. Each quiz will contain questions from the previous, as well
as the current laboratory.
Absentee Policy: A maximum of two laboratories may be missed over the course
of the semester. The first missed
lab will receive a grade based on the average of the remaining reports, provided
the absence is excused. The second
missed lab will be given a zero and students that miss more than two labs will
be given a failure for the course.
You will not be allowed to repeat a laboratory. There will be no make-up quizzes since
the lowest score out of 12 is dropped.
We will not accept partially completed reports.
Excused Absence: Students must provide a reasonable excuse or they will receive a
zero. In rare circumstances, a student may be allowed to make-up an excused
absence in another laboratory session; make-upÕs are
generally not allowed when the laboratory section is doing a different lab due
to safety and hazardous waste considerations. All make-upÕs will be at the
discretion of the instructor and in consultation with the TA. If at all possible, please inform your
TA in advance when you will miss a laboratory, this will greatly enhance your
chances of being excused. After
you return from an absence, you must fill out an Òexcused absence requestÓ form
and have it signed by your TA and myself; you may get this form from the
website.
Handing in Late Work: Prelabs must
be handed in on or before the day that the lab is performed and will NOT be
accepted late. Each week your TA
will assign a due date for the reports, typically the beginning of the next
laboratory session. Reports that
are handed in to the instructor or the TA by Monday at 5pm after the due
date will receive a 20% deduction from the total score. Reports that are one week late will
receive a 25% deduction. Any work
handed in more than one week after the due date will be reduced from 30% to
100% at the discretion of the TA, and in consultation with the instructor. Each TA has a mailbox in Neckers 224, please note that this
office typically closes at 4pm. Written work will not be accepted after
Friday, May 2.
Laboratory Safety: Organic chemistry is inherently dangerous since we work with
glassware and flammable solvents.
Explosions and spills do happen and people do get hurt, however, these
incidents are very rare when proper precautions are taken. Therefore, it is extremely important
that all students and TA's follow well-defined safety protocols. Such protocols are outlined in the
textbook (p. 15 - 23). Goggles or safety
glasses must be worn at all times when experiments are in progress. Furthermore, the instructors and
TA's will remind students of important safety precautions before each
laboratory. However, there is no substitute for preparation and common sense!
Emergency Procedures: Southern
Illinois University Carbondale is committed to providing a safe and healthy
environment for study and work.
Because some health and safety circumstances are beyond our control, we
ask that you become familiar with the SIUC Emergency Response Plan and building
Emergency Response Team (BERT) program.
Emergency response information is available on posters in buildings on
campus, available BERTÕs website at www.bert.siu.edu, Department
of SafetyÕs website www.dps.siu.edu (disaster drop down) and in Emergency
Response Guideline pamphlet. Know
how to respond to each type of emergency.
Instructors will provide guidance and direction to
students in the classroom in the event of an emergency affecting your
location. It is important that you follow these instructions and stay with your
instructor during an evacuation or sheltering emergency. The Building Emergency Response
Team will provide assistance to your instructor in evacuating the building or
sheltering within the facility.
Hazardous Chemical Disposal: Most of the chemicals that we work with
in the laboratory must be disposed of in properly labeled waste
containers. We are legally
required to make an accurate account of the contents of these waste
containers, which are found in the laboratory hoods. Thus, it is very important that you place your waste
in the appropriate container; always double-check the waste container before
you add waste.
Health Problems: It is important that you
notify the instructor and TA of any health related issues at the beginning of
the semester. Particularly if you
are prone to serious allergies or Asthmatic attacks; you should withdraw from this course if you are pregnant.
Laboratory Cleanliness: Each laboratory period the TA will
assign two people as "clean-up supervisors". It is the responsibility of these
supervisors to ensure that the entire laboratory is cleaned and prepared for
the next laboratory section. Thus,
the supervisors must wait until the other students have completed their work
and the TA inspects the laboratory before they may be excused. If the laboratory is closed and does
not pass inspection by the instructor or the laboratory coordinator, the
supervisors will have ten points deducted from their TA evaluation grade and
the TA will be reprimanded. All
students will be supervisors at least once per semester. The TA should provide a checklist with
specific cleaning duties for each lab.
Laboratory Notebook: All students are required to have a
laboratory notebook where they will record experimental data and
procedures. This notebook should
be bound, not spiral, so that the pages are not easily removed. TAÕs will periodically check the
notebook as part of the TA evaluation/Notebook grade. Notebooks play an important role in science by archiving
valuable data and procedures. A
good notebook includes detailed procedures and observations that allows someone skilled in the art of organic chemistry to
reproduce those results.
Late Entry: Requests for late entry or for changing your lab section
must be processed in the Chemistry Department office, Neckers
224. Typically these are only
approved when space is available in the requested section (20 students
maximum).
Drop Dates: Aug. 29 - last
day to withdraw without affecting your transcript.
Oct.
13 - last day to withdraw.
