Excerpt from the University Code for Academic Work:
The CNU Honor Code
"On my honor, I will maintain the highest possible standards of honesty, integrity and personal responsibility. That means I will not lie, cheat, or steal and as a member of this academic community, I am committed to creating an environment of respect and mutual trust."

Disabled Student Policy:
Any student who believes that she or he is disabled should make an appointment to see me to discuss your needs. In order to receive an accommodation, your disability must be on record in the office of Disability Support Services (Telephone 594-8763, Adm. 125).


Laboratory MATERIALS:   
Grading Policy - All Laboratory reports are due the following week, at the start of the next laboratory class. Late reports will neither be accepted nor graded.


MAKE-UP POLICY - Make-ups are not automatic. You are required to perform an experiment and submit a laboratory report for each experiment, as required by this course. You are allowed only one excused absence(It has to be a good one). Students are NOT allowed to go to another section to make up lab work without prior approval from instructor(s).


FINAL GRADE - The final grade will be determined by the following scheme: a) Laboratory Reports: each experiment will be worth 25 points, thus a total of 300 points are possible on the experiments. Your lowest laboratory grade may be dropped as well as the lowest quiz grade, provided that you complete them all. If you miss three or more experiments, you must withdraw from the lab and re﷓enroll in the course.

GENERAL CHEMISTRY LABORATORIES
  1. Be here on time and observe laboratory regulations and safety rules. There will be a quiz at the beginning of the class followed by a short lecture on the experiment to be performed that day.  If you miss the first 10 to 15 minutes of class, you will not be allowed to perform the experiment on that day.
  2. You must bring your lab manual and notebook to the lab.
  3. Experimental procedure is written in the lab notebook prior to the lab time and must be initialed at the beginning of the lab period. All entries must be in ink.
  4. Experiments are done independently and must be initialed at the conclusion of the experiment.
  5. Glassware must be cleaned after use. Clean up your working area before you leave.
  6. Goggles must be worn at all times once the lab has started.
  7. Experiments must be submitted for grading within one week after completion.
  8. When two successive laboratory sessions are missed, you will automatically be dropped from the rolls and you must withdraw from the lab or a grade of "F" will be assigned.
  9. Smoking, eating, or drinking are not allowed. Please turn off your cell phones and/or beepers.
  10. If you don’t understand something, ask before doing anything.
Laboratory Notebook Format for Chemistry Labs at CNU
All chemistry labs will follow the same lab format in order to help our students have a seamless transition between courses.  Remember that the lab notebook is a permanent record of your work in the lab.  It must be able to be read both by you and anyone else who looks at it. 

1.    Reserve the first two right-hand pages for a TABLE OF CONTENTS. Keep it up to date with the experiment number, title, and page location of each experiment.
2.    For every experiment, write the title of the experiment and the date on the top of each right-hand page.  Each new experiment should begin on a new page. Try to leave 1" margins on all sides.
3.    All lab data must be entered directly into the notebook in non-erasable ink, not recorded on lab sheets or pieces of scratch paper.  White out should NEVER be used. 
4.    Each experiment should include:
a)    Title and date;
b)    Object/Hypothesis;
c)    Flow chart of procedure(s);
d)    Chemical reagent chart (when appropriate) including molecular weight of each reagent, grams used, and moles used;
e)    Prelab questions (when appropriate);
f)    Data (in table form when appropriate);
g)    Observations in detail;
h)    Complete sample calculations explaining how results were obtained from data including units.  If using a spreadsheet, calculations must be included;
i)    Sources of error (Where are the possible errors? Did you make any?);
j)    Conclusion includes a detailed discussion of the results and how you arrived at your conclusion.  Must include unknown numbers and final answer (when appropriate).
k)    Post-lab questions (when appropriate);
l)    Signature and date.
5.  Corrections can be made by putting a single light line through the error and the correct value inserted above or after the error.  Never write over the top of an error or try to make it unreadable.
6.    Units must be included with numerical entries and correct significant figures must always be used.
