The course is impacted; there is neither make-up time in the course nor space for you to work in other sections. You must do your lab work in your scheduled period. In preparation for the lab, you should first study the pertinent sections in the text, review the lecture notes pertaining to the experiment, then view (and possibly review) the appropriate videotapes (refer to lab schedule) for any new techniques to be used in the experiment. Prelab report is required for each experiment. For the prelab reports, you should write the introduction, procedure (including a reference to the original source and a flow-chart summary of the experimental steps), and data tables for the experiment in the notebook before the lab section meets. Pre-lab study problems must also be completed (if assign) before your lab section meets. During lab, you will complete the data tables and record any other observations about the experiment. In addition, you may be required to obtain physical properties as well as safety information for different chemicals for each experiment from the on-line MSDS (Material Safety Data Sheets) database. MSDS is available on the internet (refer to the MSDS handout for details). You are welcome to use the computers located in Rm. 1054 or 4335 or 4336 Young Hall to access the MSDS. Names of those chemicals which require the use of MSDS to obtain safety information will be posted with the pre-lab guidelines. You MUST turn in the duplicate copy of the pre-lab to your TA at the beginning of the lab period. A copy of the in-lab data is to be turned in to the T.A. at the end of the lab period. Late pre-lab work will count as ZERO. NOTE: Techniques videotapes can now be viewed on the internet (refer to the lab schedule for web address). Post-lab Reports: The remainder of the lab report, - the data analysis, error analysis, and conclusions - are to be completed in the lab notebook after the experiment is completed. Unexcused late post-lab portions of the reports, will accrue a penalty of five percent of the grade per day. No reports will be accepted after 5:00 p.m. on the last day of instruction. Computer programs used to analyze data must be referenced and copies may be requested by the instructor. Safety Goggles and Protective Clothing: Eye protection must be worn in all laboratories whenever any laboratory work is in progress. Recommended safety goggles may be purchased from the Undergraduate Chemistry Fraternity - AXE - Room 1275 Young Hall. Other styles of goggles are available at local bookstores. A heavy vinyl or rubberized apron or full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental work. Aprons may be purchased from AXE or the student store. If you wear an apron, your shirt must cover your shoulders and upper arms. Shorts and sandals do not provide adequate protection for laboratory work. You will be barred from the laboratory if you are not wearing appropriate protective clothing. Latex gloves will be provided for those experiments using chemicals that are hazardous to skin. Chemistry 30AL is graded on a mastery basis. Letter grades are based on the course point total. (Please note these grades are assigned only at the end of the quarter when all items have been graded; the percentage on a portion of the course is not a meaningful measure of your total performance.) Plus and minus grades are frequently assigned, but final decisions to award these grades are not made until the end of the quarter when all the student data have been evaluated. As a rule of thumb, the course grades are assigned as follows: 90 - 100% = A ; 80 - 90% = B ; 65 - 80% = C ; 50 - 65% = D ; 0 - 50% = F Cheating, Plagiarism, Dishonesty: All cases of cheating, plagiarism, or dishonesty will be reported to the Dean of Students. All work that you submit for grading must be your own work. Group reports must acknowledge the individual contributions of each person, if the work has been
