Information Regarding CHEM 202 Lab:

Lab work is an integral part of the CHEM 202 course. Lab attendance is important and you must attain a minimum of 130 total lab points to pass the course regardless of the lecture grade. It is important that you complete the pre-lab assignment BEFORE the day of the lab so that you are familiar with:

The lab procedure and can conduct the lab in a time efficient manner ,

The equipment used and the lab techniques involved, and

The calculations used in the lab.

All labs are worth 25 points and the grade will be based on the best 10 out of 12 labs. There are NO MAKE UP LABS. Lab reports are due by 5:00 p.m. the day after the lab session is completed. A penalty of five points per day will be levied for late labs. Lab reports may be turned into the Teaching Assistant or Graduate Assistant or at Currens 214 to the Teaching Assistant’s or Graduate Assistant’s mail box. Labs MUST BE marked with the following: Student’s Name, Course Number, Section Number, TA/GA’s Name. Failure to exclude this information may result in a zero for the lab.
