during the lecture section or during the lab section if the exam is in lab exam in which you are officially enrolled Any missing exam will count as ZERO Lab quizzes if any must be taken during the lab section in which you are officially enrolled NO EXCEPTION There is NO MAKE UP for missing exams regardless of reasons 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 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

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 now be viewed on the Internet refer to the lab schedule for Web address COURSE INFORMATION continue Required Texts 1 Chemistry 14B CL Lab Manual For Life Science Majors 2 Introduction to Organic Laboratory Techniques A Microscale Approach 3rd Edition by Pavia Lampman Kriz and Engel ISBN 0030265665 Recommended Text Peter Atkins and Loretta Jones Chemical Principles The Quest for Insight 2nd Ed or any other equivalent general chemistry text 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
