A = 90%
B = 80%
C = 65%
300 points
100 points

50 points
D = 55%
MAKE-UP POLICY:
No make-ups are allowed for the experimental or discussion portion of the class. Late laboratory reports will be
deducted 5 points per day (including weekends).
ATTENDANCE POLICY:
Attendance is mandatory. This is a laboratory class. You must be present to complete the requirements. If you
miss one (1) laboratory with an excused absence I will recalculate grade. Unexcused absences result in a zero for
that experiment.
ACADEMIC HONESTY POLICY: Any student found cheating, including plagiarism, will be subject to the penalties
as stated in the Student Code of Conduct handbook; including but not limited to a score of zero on exam, review or
report, expulsion from the class or expulsion from the University.
SEMESTER WITHDRAWALS : The last day to withdraw from the class with a “W” is Wednesday 31 March 2010.
ACADEMIC DISABILITIES POLICY: If you have a documented disability that requires assistance, you will need to
register with the Office of Disability Services for coordination of your academic accommodations. The Office of
Disability Services is located in Peltier Hall, Room 100-A. The phone number is (985) 448-4430 (TDD 449-7002).
ACADEMIC GRIEVANCES. The proper procedure for filing grade appeals or grievances related to academic matters
is listed in Section 5 of the Code of Student Conduct and at he following link:

CONTINUED LEARNING FOLLOWING AN EXTREME EMERGENCY:
In order to make continued learning possible following an extreme emergency, students are responsible for:
 reading regular emergency notifications on the NSU website;
 knowing their Blackboard (or designated system) student login and password;
 knowing how to use and access Blackboard (or university designated electronic delivery system);
 being familiar with emergency guidelines;
 evacuating textbooks and other course materials;
 contacting faculty regarding their intentions for completing the course.
Faculty are responsible for:
 their development in the use of the Blackboard (or designated) software;
 having a plan for continuing their courses using only Blackboard and email;
 continuing their course in whatever way suits the completion of the course best, and being creative in the
continuation of these courses;
 making adjustments or compensations to a student's progress in special programs with labs, clinical
sequences or the like only in the immediate semester following the emergency.
CLASS DISRUPTIONS: The use of cellular phones, pagers or any other electronic personal devices is prohibited in
class. Any infractions will result in class being dismissed and experiments considered over.
This includes but not limited to
 using your phone as timer—get a watch or I will supply stopwatches if needed,
 going to the hallway while a experiment is ongoing to check on texts.
 texting or calling or receiving incoming calls or texts
 receiving alerts regarding incoming texts or calls
 using phone as alarm system.
NOTEBOOK
Notebooks must be written legibly to avoid loss of points.
Prelab Due before beginning the experiment.
 TITLE
 DATE
 PURPOSE Describe what is expected of the laboratory. This should be only one or two sentences, in your own
words--do not copy from the manuals.
 PROCEDURE A flow diagram is best. Abbreviated version of what you will be doing. Read the lab and be
familiar with what will be happening. Summarize the steps.
 DATA TABLE Listing of all of the reagents and solvents used in the experiment. List in table form only.

 CHEMICAL EQUATIONS Write all of the major chemical reactions and side reactions for the experiment.
Include the amounts called for in the experiment (which is the limiting reagent?) and the theoretical yield. Not
necessary for the distillation, melting point, or crystallization experiments.
You may not begin the experiment until the prelab section is completed and checked by instructor.
Postlab
 OBSERVATIONS All data and everything that occurs in lab as it happens. Colors, smells, amounts used, mixing,
temperatures, apparatus used, time for reaction, spills if they occur etc. Draw pictures if appropriate, use
tables, graphs, equations, etc. Record details such as Instrument name and maker, model number and serial
number, chemical manufacturer, grade, lot number, expiration date, etc. This section cannot be too long.
Spectra are also to be included with this section. Due at the end of lab.
 CALCULATIONS Theoretical yield, Percent Yield, Atom Economy, Economical Analysis
 POST LAB QUESTIONS: Answer the post lab questions that are listed at the end of each experiment.
