|NOTE: Chemistry 14CL includes topics already covered in 14A/B and 14BL.
In order to understand the lectures and do well in the labs (these include
prelabs / postlabs and exams), it is important for all of you to review
(on your own!) all those relevant materials from Chemistry 14A/B and 14BL.

To complete the laboratory work on
time you must prepare for the period's assignment before your laboratory
section meets if you wish to complete the experiment in the time allotted.
The course is impacted; there is neither make-up time in the course nor
space for you to work in other sections. You must do your lab work
in your scheduled period. In preparation for the lab you should first
study the pertinent sections in the text, review the lecture notes pertaining
to the experiment, then view (and possibly review) the appropriate videotapes
for any new techniques to be used in the experiment. Write the introduction,
procedure (including a reference to the original source and a flow-chart
summary of the experimental steps), and data tables for the experiment
are to be written in the notebook before the lab section meets. During
lab, you will complete the data tables and record any other observations
about the experiment. If you still have questions relating
to the experimental details, consult a TA or the course instructor.
The duplicate copy of the pre-lab assignment and in-lab work is
to be turned in to the T.A. at the end of the lab period. Late
pre-lab work will count as ZERO.
The remainder of the lab report, - the data analysis, error analysis,
and conclusions - are to be completed in the lab notebook after the experiment
is completed. The original copy of this portion of the report is
turned in to the T.A. at the start of the following lab period along with
any graphs that have been prepared on fine-grid (millimeter) graph paper.
Unexcused late post-lab portions of the reports, will accrue a penalty
of five percent of the grade per day for unexcused late reports. No reports
will be accepted after 5:00 p.m. on the last day of instruction. Computer
programs used to analyze data must be referenced and copies may be requested
by the instructor.
The course bulletin board is located
on the wall across from rooms 1217 and 1225. Report Guidelines will
ONLY be posted on 14CL VOH (Virtual Office Hours) homepage.
Operated by the Instructional Media
Library, and located in Powell 270. This facility is open daily. Videotapes
for assignments on the laboratory schedules will be available for individual
student viewing. You are expected to view the approporiate program for
the week's experiment before your lab section meets.

Safety Goggles and Protective Clothing:
Eye protection must
be worn in all laboratories whenever any laboratory work is in progress.
Recommended safety goggles may be purchased from the Undergraduate Chemistry
Fraternity - AXE - Room 1275 Young Hall. Other styles of goggles are available
at local bookstores.
A heavy vinyl or rubberized apron or
full-length lab coat, closed-toe shoes, and long pants must be worn when
doing experimental work. Aprons may be purchased from AXE or the student
store. If you wear an apron, your shirt must cover your shoulders and upper
arms. Shorts and sandals do not provide adequate protection for laboratory
work. You will be barred from the laboratory if you are not wearing appropriate
protective clothing. Latex gloves will be provided for those experiments
using chemicals that are hazardous to skin.
Laboratory notebooks designed for
duplicate records are available from the Undergraduate Chemistry Fraternity
- AXE - Young Hall 1275 and the student store. All experimental data and
complete reports will be recorded in this laboratory notebook.
Your mastery of the course will be
measured through your performance on the exams, reports, experimental accuracy,
calculations and analysis of data; and your lab technique. Qualities that
will be considered in this latter category include your performance in
observing safety regulations such as wearing eye and personal protection
in lab, following safe lab procedures, working independently and coming
to lab prepared, completing the assigned work within the scheduled laboratory
periods, coming to lab on time and turning in assignments promptly, and
disposing of waste in proper receptacles.
Chemistry 14CL is graded on a
mastery basis. Letter grades are based on the course
point total. (Please note these grades are assigned only
at the end of the quarter when all items have been graded; the percentage
on a portion of the course is not a meaningful measure of your total performance.)
Plus and minus grades are frequently assigned, but final decisions to award
these grades are not made until the end of the quarter when all the student
data have been evaluated. As a rule of thumb, the course grades are assigned
90 - 100% = A
80 - 90% = B
65 - 80% = C
50 - 65% = D
0 - 50% = F
Cheating, Plagiarism, Dishonesty:
All cases of cheating, plagiarism, or dishonesty will be reported to
the Dean of Students. All work that you submit for grading must be your
own work. Group reports must acknowledge the individual contributions of
each person, if the work has been shared.
