Grading:

There will be three (other than the final) examinations.  Final examination is a comprehensive examination. First three exams will be weighted equally 100 points and the final is worth 200 points.   Tentative grade ranges: A = 100-91%, B = 90- 81%, C = 80-71%, D = 70-60%. These cutoffs may be lowered.

Quizzes/assignments are assigned via 'Sapling' on line homework system. You will have to enroll in this system. Please read the instructions for enrolling in the Sapling on-line system.

Attendance: Please see the university attendance policy at https://www.mnstate.edu/policies/absences.aspx. Any absences over and above the allowed number would result in a loss of 10 points per class missed form the final grand total (maximum possible 600).

Exam dates (lecture):

First Examination 100 points February 10
Second Examination 100 points March 24
Third Examination 100 points April 21
Homework Assignments 100 points
Final Examination 200 points please see the final exams schedule

Ground Rules (Lab):

The grading of this CHEM380 lab course will be based on the notebook entry (hand in) and the results. Always try to maintain a neat notebook.
Maintain a table of contents in the note book.

Sketch a flow chart for the procedure of each experiment, before the laboratory period, in the notebook.

The note book entry should contain the title of the experiment, date, steps  (flow chart) of the procedure; annotate all observations and indicate the proper units, (tabulate observations with proper units, wherever possible); graphs (computer outputs) must be properly titled and axes labeled with units, show best fit line equation and the goodness of fit of the plot (R2). Write all chemical reactions involved and for mathematical equations clearly define symbols. Show all calculations with annotations and results in the notebook.

Sources of all data, information and apparatus (indicate model, make, serial number if applicable), reagents and their concentrations must be fully documented.

Please annotate/document all intermediate steps of calculations and final results. Do not leave numbers without a statement (annotation) to indicate what they are. Show proper units. Do not give numbers without proper units.

When computer outputs are generated, paste two copies (do not staple) on the two appropriate pages of the notebook. Make sure that  such outputs are correctly sized so that they could be pasted in the proper space on the notebook pages. 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 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 place your initials.

The final result must be expressed to the correct significant figure along with the standard deviation (relative and absolute) and the confidence interval if appropriate. Indicate the relevant physical conditions (temperature, pressure) of the experiment and literature values of experimentally determined quantities along with their references. Include a discussion section wherever possible.

The 'original copy' of the 'notebook material' must be handed in within a week of the completion of the lab.

For late hand-ins five points (of possible 100) will be reduced for every delayed day.

Each lab will be graded based on the presentation, accuracy and precision of the results as presented.

Overall Course Grade: 60% lecture, 40% lab.

Use computer programs for all data analysis whenever possible.
