The log-in is http://voh.chem.ucla.edu. Please use this address for general class-related questions. Note that if you send a confidential memo to the instructor through voh, you must include your e-mail address in the memo if you wish an answer.

You are expected to do your lab work in your scheduled period; your grade will be affected by not completing lab work in a timely manner. 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 for any new techniques to be used in the experiment. Following the instructions in the report guidelines posted on VOH, complete any assigned pre-lab study questions in your lab notebook. Then write the assignment introduction, procedure (including a reference to the original source and a flowchart summary of the experimental steps), and set up the data tables for the experiment in your notebook before the lab section meets. This preliminary work is due during the first fifteen minutes of your lab period. No credit for pre-lab work will be given after this time. Any student who has not completed the preliminary work, will be required to complete the preparation before commencing lab work. During lab, you will complete the data tables and record any other observations about the experiment. The duplicate copy of this in-lab work must be turned in to the TA at the end of the lab period if you are to receive credit for the assignment. 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 duplicate copy of this portion of the report is turned in to the TA 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. No reports will be accepted after more thantwo weeks late or 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. Academic Integrity: 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 shared.Approximate Grading Distribution: Preparation for lab 17% Lab Reports 32% Technique and Accuracy 13% CPR writing (3 @ 10 each) 5.5% In-lab workshops 5.5% Exams 27% Lab Maintenance up to -1% per day To receive a passing grade (C-) you must receive at least 50% of the points in each of the six grading areas. Lab technique includes but is not limited to, attending lab on time and completing the work in the assigned time, leaving your work area and the equipment you use clean and in a condition that the next person can begin work, observing safe practices in the lab, timely submission of lab work, and appropriate contribution to group work and reports. Labs, instrument rooms, and lab areas left in a condition that prevents the students in a subsequent section from beginning their work in a timely manner will result in a 1% penalty assessed against students in the previous section.
