The address is http://voh.chem.ucla.edu Lecture Schedule : April 1 Introduction, Equipment May 6 Acid-Base Equilibria I April 8 Measurements, Concentrations May 13 Acid-Base Equilibria II April 15 Recrystallization, Melting point determination May 20 Spreadsheets April 22 Beer’s Law May 27 Memorial Day – no class April 29 Midterm Exam 1 June 3 Midterm Exam 2 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;1 there is neither make-up time in the course nor space for you to work in other sections. You must to 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. Following the instructions in the posted report guidelines, write the introduction, procedure (including a reference to the original source and a flow-chart summary of the experimental steps), MSDS information about the chemicals you will be using, 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 TA 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 finished. 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 5:00 p.m. on June 7, 2002. 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. Group reports must acknowledge the individual contributions of each person, if the work has been shared. Bulletin Board: The course bulletin board is located on the wall across from the vending machines on first floor of Young Hall. Report guidelines will ONLY be available on the 14BL VOH (Virtual Office Hours) homepage. 1 The last day to drop Chemistry 14BL is April 12. 2 Available on line at http://www.oid.ucla.edu/Webcast/Chemistry/index.htmlRequired Texts: Chemistry Experiments for Life Science Majors (2nd Ed) Russell, Burgess Publishing (1999) Introduction to Organic Laboratory Techniques – A Microscale Approach (3rd Ed) Pavia, Lampman, Kriz and Engel Saunders College Publishing (1998)# Recommended Text: Peter Atkins and Loretta Jones, Chemical Principles - The Quest for Insight (1st or 2nd Ed) (or any other equivalent general chemistry text) 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 -AXE4 - Room 1275 Young Hall. Other styles of goggles are available at local bookstores. A full-length lab coat, closed-toe shoes, and long pants must be worn when doing experimental 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. 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 must be recorded in this laboratory notebook. Grading Distribution: Prelab Assignments 80 Lab Reports 100 Technique 20 CPR writing (3 @ 10 each) 30 Exams (2@50 each) 100 Lab Protocols 30 Total 360 Lab Maintenance up to -5 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 penalty of 5 points assessed against students who were assigned to the area in question in the previous section.
