Grading: To receive a passing grade (C-), you must complete ALL the experiments and reports and receive at least 50% of the points in the exams category.

Any missing exam will count as ZERO.Chemistry 30AL COURSE INFORMATION (CONTINUE) Fall 2004 Lab Preparation: 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; therefore, there is neither make-up time in the course nor space for you to work in other sections. If you miss a lab, you MUST discuss the issue with the course instructor to see what other options you may have to complete the experiment. 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 videos (refer to lab schedule for on-line access of the videos) for any new techniques to be used in the experiment. If a pre-lab report is required for the experiment, you MUST turn in the pre-lab report to your TA at the beginning of the lab period. Refer to the VOH for the specific report guidelines. In addition, you may be required to obtain physical properties as well as safety information for different chemicals for your pre-lab reports from the MSDS (Material Safety Data Sheets) database. MSDS is available on-line (refer to the MSDS handout). During the lab period, you will also complete the data tables and record any other observations about the experiment. 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 videos can also 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 (check VOH for guidelines). The post-lab report must be turned in to the T.A. at the start of the lab period listed under “Due Date” on your lab schedule. Unexcused late post-lab 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. Laboratory Notebooks: Laboratory notebooks designed for duplicate records are available from the Undergraduate Chemistry Fraternity - AXE - Young Hall 1275 and the student store. All experimental data and complete reports will be recorded in this laboratory notebook. 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. A heavy vinyl or rubberized apron or full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental work. Lab coat can be purchased from AXE. If you wear an apron, your shirt must cover your shoulders and upper arms. Shorts and sandals are NOT allowed in the laboratory. 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. Note: AXE only accepts personal check when purchasing lab equipment. AXE DOES NOT accept cash or credit card! 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
