Information Regarding CHEM 201 Lab: Lab work is an integral part of the CHEM 201
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 quiz (found on Western Online) and study all relevant materials
BEFORE the day of the lab so that you are familiar with:
1. The lab procedure and can conduct the lab in a time efficient manner ,
2. The equipment used and the lab techniques involved, and
1
3. The calculations used in the lab.
All take-home pre-lab quizzes are worth 5 points. The quizzes are given in the lab
manual for each laboratory exercise. The lab grade will be based on the best 10 out
of 12 labs quizzes and lab reports. There are NO MAKE UP LAB QUIZZES.
All labs are worth 15 points and the lab grade will be based on the best 10 out of 12
lab reports. There are NO MAKE UP LAB REPORTS. Lab reports are due by 4:30
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 at
Currens 107 to the Teaching Assistant’s mail box.
Lab reports MUST BE marked with the following: student’s name, course number
(CHEM 201), lab section number, lab meeting time, and the TA’s full name. Failure
to include this information may result in a zero for the lab report.
The laboratory final examination will be worth 50 points. The laboratory final
examination will cover the principles and applications of laboratory techniques,
calculations and safety procedures for CHEM 201
Students with Disabilities: In accordance with University values and disability law,
students with disabilities may request academic accommodations where there are
aspects of a course that result in barriers to inclusion or accurate assessment of
achievement. To file an official request for disability-related accommodations, please
