Ground Rules (Lab):

All experiments must be completed. The grading of this CHEM480 lab will be based on

of overall 100% of the lab grade. Sketch a flow sheet for the procedure of each experiment, before the laboratory period. The note book should contain  key steps in the procedure, all observations, (tabulated wherever possible), graphs (drawn on engineering paper or computer outputs), chemical and mathematical equations with symbols clearly defined, all calculations and results. Maintain a table of contents in the note book.

Sources of all data, information and apparatus (indicate model, make, serial number if applicable), reagents must be completely documented. All calculations must be done in the note book. If any computer outputs are generated, paste a copy (do not staple) of such outputs in the note book. Pasted sheets of paper must be signed at two places with the signature running through the pasted paper and on to the notebook paper.  Give the computer file name, software used with version and file date. 

Blank pages must be explained e.g. indicate "page left blank for spacing". Any corrections made must be indicated with a single line through the discarded part.  Explain why the discarding was done and initial.

Report: Include the title of the experiment, date, theory, balanced chemical equations, all mathematical equations (with symbols defined) used in the interpretation experiment, all equation(s) of the best fit curves(s) (with symbols defined), and calculations (computer generated or otherwise). The final result must be expressed to the correct significant figure along with the standard deviation (relative and absolute), relevant physical conditions of the experiment and literature values of experimentally determined quantities along with their references.  Include a discussion section as well.

Please write statements for all intermediate steps of calculations and final results. Do not leave a bunch of numbers without a statement to indicate what they are.  Show proper units.  Do not give numbers without proper units.

The 'notebook material' should be handed in within a week of the completion of the lab on the closest friday.

Notebooks will be graded based on the presentation, accuracy and precision of the results.

For late hand-ins five points will be reduced for every delayed day.

Final Grade CHEM480: based on 100 points, 70% lecture score + 30% laboratory score.

Disability Access statement:

Students with disabilities who believe they may need an accommodation in this class are encouraged to contact Greg Toutges, Coordinator of Disability Services at 477-5859 (Voice) or 1-800-627-3529 (MRS/TTY), CMU 222 as soon as possible to ensure that accommodations are implemented in a timely fashion.

Safety glasses must be worn at all times during laboratory work.

Please turn off cell phones.

Please do not use the intenet and printers for anything other than coursework for CHEM480 during the class time. Thanks.
