Chemistry 343 - Fall 2012 - UIC Department of Chemistry
Laboratory: At a minimum you must perform all of the LabWorks experiments and the six instrumental experiments and turn in, in a timely manner, a laboratory report for each of these six experiments. Failure to comply will result in a grade of an F. In addition, you are required to attend all the pre-lab discussions. You will not be allowed to conduct an experiment if you fail to attend a prelab discussion for a corresponding experiment, which results in a grade F for the class. You must also consecutively attend all lab periods until your experiment is completed. You should read all background material and lab handouts before coming to the lab. You will be quizzed on the material to check your preparedness. If the TA determines that students from a particular group are unprepared for the experiment, they will be asked to leave the lab until such preparation can be completed and demonstrated. Five points will be taken from the points for the corresponding lab if you are 10-15 minutes late; you will have a 20-point reduction if you are 15- 30 minutes late. You will receive a zero point for the experiment if you are more than 30 minutes late. Work must cease 10 minutes before the end of the lab and you must leave the lab by the end of the period with no exceptions. There are no make-up labs for the experiments! Grading: Your grade will be based upon the following: LabWorks: 100 points (30 points for performance and 70 points for oral presentation) Instrumental Experiments: 6 at 150 points each, 900 points 10 points for pre-lab discussion 20 points for pre-lab quiz 20 points for performance* 100 points for the report writeup* Lecture: 100 points (20 points for attendance; 80 points for quiz and homework). No late assignments will be accepted. Notebook (turn in with each lab report and at end of semester), 150 points Final Exam: 200 points Total Points: 1450 points There is no curve for this course. Your final letter grade is determined directly from your total score for the semester. A: 90 or better, B: 80 or better, C: 70 or better, D: 60 or better. Any score below 59 corresponds to F. *If a student as part of a group does not assist to a reasonable degree (i.e. the experiment takes two days but one group member is absent on one day) then that student will forfeit ½ the performance score and ½ the data analysis points, which is variable depending on the identity of the lab. A student not present for the entire lab will receive 0 points. Academic Dishonesty: In all work (examinations, quizzes, laboratory data and reports) you must adhere to the guidelines regarding academic honesty as described in the UIC Student Handbook. No academic dishonesty will be tolerated! A student who will be caught and proven to have committed an act of academic dishonesty on any homework set, quiz or examination, will receive a zero for the particular item and will automatically fail the course. The dishonest student will be reported to the Head of the Chemistry Department and to the Dean of the School of Liberal Arts and Science.
LABORATORY NOTEBOOK You and your lab partner are required to individually each have a bound laboratory notebook (does not need to have carbon copies) in which you keep a record of all of your lab activities. You should record the pertinent information for each experiment in the notebook. For some experiments all data acquired will be entered directly into a computer file. For such experiments it will suffice to record the filename along with a brief description of the file contents. These files should be stored on your laboratory 3 floppy disk. Your lab notebook will be turned in for grading with each lab report submitted and at your last laboratory session. The notebook must follow this format: 1. Contain a table of contents. 2. Pages numbered and dated. 3. No pages torn out. 4. All data, analyses and comments written legibly in blue or black ink. 5. All data entered directly into the notebook. Your TA will confiscate data written on loose sheets. 6. Data pages signed by your TA on date the data is recorded. 7. All analysis of data and results recorded on notebook. 8. Plots and graphs computer generated and a least one-half page large. Fitting of data to straight lines must be done by a linear least squares regression method, with slope, intercept and correlation given. In addition the standard deviation of the fit, slope and intercept should also be given. For your plots you may use any statistical software package like SigmaPlot, Igor, PSI Plot or Origin. Plots done by Microsoft Excel cannot be used for professional purposes. 9. Additional plots or other computer-generated material should be neatly taped into the notebook. LABORATORY REPORTS Laboratory reports that are typed with a word processor (computer-generated) are due at the beginning of the period one week after an experiment is concluded using the format given in the Physical Chemistry Laboratory Manual entitled as “Physical Chemistry Laboratory Reports”. Lab reports are accepted up to seven days after the due date but will have 25 points deducted. Lab reports will not be accepted which are more than one week late, and will result in assignment of a grade of an F for the course. Your lab notebook is also to be submitted along with lab report. Your notebook will be checked for being appropriately used. This course fulfills the “Writing-in-the-Discipline” requirement. As such, by end of the course you are expected to be able to report scientific results from your experiments in a literate and rigorous manner. This not only involves a concise style of prose but proper error analysis and adequate graphical representation of data. Thus an important factor in grading the lab reports will be the quality of writing-grammar, spelling, clarity, organization- and the proper employment of tables, graphs and error analysis. SAFETY You are required to adhere to your TA’s instructions as your TA supervises you in the laboratory and maintains the safety standards. You are required to wear safety goggles while doing the
