Course objectives: My goal for this course is
to clearly explain the fundamental concepts of organic chemistry through
laboratory experimentation and report writing.
The specific objectives include:
Office Hours: TR
10:00 AM – 11:00 AM
or by appointment (323-4927 or
grattanc@winthrop.edu)
I will also be accessible to answer questions on email. You will find that this course is different
than any other courses you have taken in college. It is therefore important to stay on top of
the material and get your questions answered as soon as possible. Please take advantage of my office hours or
email to resolve these problems.
Attendance: Due to the unique nature of this course, each
and every class meeting is important to better understand the material in the
text. The students are responsible for
all assignments for the course regardless of absence. Based on University policy, when a student
has missed 25% of the class meetings (11), he/she automatically receives an “N”
for the course.
Grading: 10 Lab reports 1000 points
The grading scale for this course will be based
upon a typical 93-100% (A), 90-92% (A-), 87-89%(B+), 83-86% (B), 80-82% (B-),
77-79% (C+), 70-76% (C), 60-69% (D) < 60%(F) distribution using the total
points in the course.
Laboratory
Reports: Each
laboratory exercise will be evaluated on the basis of an individual Laboratory
Report for that exercise. The Laboratory Report consists of
1 Pre-Lab
Worksheet (40 pts) – Turned in at the beginning of the pre-lab briefing
Before
the beginning of each new laboratory, a Pre-Lab Worksheet (found in the
experimental procedure) must be completed. This worksheet is due at
the beginning of the pre-lab briefing. No late Pre-Lab Worksheets
will be accepted.
2. An
In-Lab notebook record (20 pts) – Turned in Wednesday after lab
An In-Lab notebook record is due each
Wednesday at 5:00 pm following the completion of that week's lab. The
In-Lab notebook record consists of the carbon copies of your notebook pages for
that laboratory exercise (an example notebook entry can be found on the course
webpage). This In-Lab record is to be done in the laboratory and
should be written directly into your lab notebook. If you do not write this
portion directly into the required notebook, you will not get credit for this
section. Your notebook record should contain:
Procedure
Write
a step-by-step account of what you did in the experiment. It should be detailed
enough so that the experiment could be repeated exactly as you did it, using
only your procedure.
Data and Observations
Record
any data (masses, mp, bp, etc.) you measured, including units. Record any
significant observations (color change, evolution of gas, precipitation, etc.).
3. A
Post-Lab Worksheet (40 pts) – Turned in Wednesday after lab
A Post-Lab Worksheet is due each
Wednesday at 5:00 pm following the completion of that week's lab. The
Post-Lab Worksheet is also included in the experimental procedure on the course
webpage (chem.winthrop.edu). A 5
point per day penalty will be assessed on Post-Lab Reports turned in late.
Withdrawal policy: In order to drop CHEM 311, you must also drop CHEM 310.
General
Lab Order:
-
Only dispose of waste in containers labeled for waste collection Do not put any chemical waste in the
trash, down the drain or in any container not labeled as waste.
-
Replace lids on all containers immediately after use. Open containers increase everyone's
exposure to the substances within them. Spills are also more likely when a
container is open. Some reagents can also be ruined by excessive exposure to
air.
-
Clean your glassware
after each experiment.
-
Clean up any spills you create. If you don’t know how a spill should be cleaned
up, ask.
-
Put things back where you found them (equipment and anything
non-disposable).
-
Dispose of broken glass, used pipets and capillaries in the white broken glass
containers.
Lab Safety:
-
SAFETY GLASSES ARE MANDATORY ANY TIME YOU ARE IN THE LAB. Even if you are simply recording data,
safety glasses must be worn. If you are found not wearing safety glasses, you
will be asked to leave and will receive a zero for the experiment.
-
Wear sensible
clothing. Shoes and shirts are required. Long hair needs to be
pulled back. Sandals, open-toed shoes, and high heels, as well as shorts,
short skirts, bare midriffs and backs are prohibited. It is best not to
wear your good clothes into the lab, since spills are common.
-
Eating, drinking and smoking are prohibited in the labs.
-
Report any spills, cuts, burns or breakage of glassware immediately. Accidents
happen and they will not affect your grade.
-
Report any malfunctioning equipment (Mel Temps, hot plates, etc.).
-
Particularly noxious substances should be handled in a fume hood. The constant
draft of air prevents exposure to harmful fumes and vapors. Make certain the
sash is lowered to a safe level, as shown on the side of the hood.
-
A safety shower located in each laboratory. These are to be used in the event
of a major spill of a hazardous chemical on yourself.
-
Each laboratory has an eyewash station to be used if a chemical has come in
contact with your eyes. Just place your face between the two fountains and
press the lever to activate the water. Try to keep your eyes open as best you can,
as this flushes them much more effectively.
-
Disposable gloves can be found on the shelves of each laboratory. Wear gloves
when dealing with any hazardous chemical. You may even want to wear gloves at
all times in the laboratory. If you get a hazardous chemical on your gloves,
take them off within a few minutes, wash your hands and put on a fresh pair.
Gloves are not impervious; they simply prevent immediate exposure.
