Any missing exam will count as ZERO. Lab Preparation and Pre-lab Reports: You must be prepared for the experiment before you come to lab if you wish to complete the experiment in the time allotted. 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 for any new techniques to be used in the 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 before your lab section meets. During lab, you will complete the data tables and record any other observations about the experiment. In addition, you will 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. More specifically, you are required to obtain physical properties such as density (or specific gravity), melting point, boiling point and hazardous information for various chemicals. MSDS (from Utah University or any other sites from UCOP) are available on-line through the UCLA Chemistry departmentalhomepage. The Web address is http://www.chem.ucla.edu/. MSDS homepage is listed under Library and Resources (select Chemistry Resources on Internet). You are welcome to use the DELL computers in Rm. 1054 to access to the MSDS homepage. 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 this pre-lab to your TA at the beginning of the lab period. In-lab work is to be turned in to the T.A. at the end of the lab period. Late pre-lab work will count as ZERO. 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. The original copy of this portion of the report is turned in to the T.A. at the start of the following lab period along with any graphs that have been prepared on fine-grid (millimeter) graph paper. Unexcused late post-lab portions of the reports, will accrue a penalty of five percent of the grade per day for unexcused late reports. 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. Video Laboratory: Operated by the Instructional Media Library, and located in Powell 270. This facility is open daily. Videotapes for assignments on the laboratory schedules will be available for individual student viewing. You are expected to view the approporiate program for the week's experiment before your lab section meets. The videotapes for the assignments are also available to be viewed on the internet at: http://www.oid.ucla.edu/Webcast/Chemistry and for students living in the dorms, the programs are viewable on UCLA Cable channel 22. 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
