Spring 2003 Course Information Chemistry 14CL Instructor: Arlene A. Russell Office Hours: Young Hall 1039 [email protected] Tuesday 3pm, Wed 8am Lecture: Monday 1 pm CS 76 Lab: various times Young Hall 1336 and 1340 Virtual Office Hours: Chemistry 14CL will use the Department of Chemistry's virtual office hour function on the Internet for correspondence and discussion. 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. Lecture Schedule: March 31 administration, polyprotic acids, amino acids April 7 polyprotic acids continued April 14` extraction April 21 infrared spectroscopy April 28 midterm exam May 5 NMR May 12 MS, UV May 19 distillation May 26 Memorial Day, no class June 2 chromatography 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; failure to do so may affect your grade. The course is impacted; there is neither make-up time in the course nor space for you to work in other sections. Only in exceptional cases, which must be approved by the instructor, will you be allowed to do lab work outside your regularly 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. Following the instructions in the lab manual and posted report guidelines, 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 your notebook before the lab section meets. You are also required to complete the pre-lab study questions in your lab notebook before the section meets. During lab, you will complete the data tables and record any other observations about the experiment. The duplicate copy of this pre-lab and in-lab work is to be turned in to the T.A. at the end of the lab period. No credit for the pre-lab work will be assigned after its due date. 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 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. No reports will be accepted after more than two 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.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 that is documented in your own lab notebook. Group reports must acknowledge the individual contributions of each person, if the work has been shared.Approximate Grading Distribution Prelab Assignments 17% Lab Reports 43% Technique 10% CPR writing (3 @ 10 each) 5% Exams 25% Lab Protocols 3% 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 protocols include but are 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 section from beginning their work in a timely manner will also result in a 1% penalty assessed against students who were assigned to the area in question in the previous section.
