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 discuss the issue with the course instructor to see what other options you may have to complete the experiment

and possibly review the appropriate videotapes refer to lab schedule for any new techniques to be used in the experiment For the pre lab reports you should 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 the notebook before the lab section meets Pre lab study problems must also be completed if assign before your lab section meets During lab you will complete the data tables and record any other observations about the experiment In addition you may be required to obtain physical properties as well as safety information for different chemicals for each experiment from the on line MSDS Material Safety Data Sheets database MSDS are available on line refer to the MSDS handout If
