A working knowledge of college algebra
CHEM 211
· Execute written chemical procedures, individually and as part of a team.
· Recognize different types of chemical glassware and laboratory equipment.
· Collect and interpret data properly by using appropriate significant figures and recognizing how this affects the quality of the results.
· Follow proper safety and disposal protocols.
The students are expected to adequately prepare prior to the laboratory meetings by reading the sections "Background Information" and "Procedure" and to complete the sections "Pre-lab Assignment" for each laboratory experiment to be performed. The TAs at the beginning of each experiment will check for completion of the Pre-lab Assignments. Additionally, all "Data Sheets" must be completed before students leave the lab. Proper labeling of the lab reports includes the student’s full name, ID number, school, and lab partner.
Full participation in all laboratory experiments is required for successful completion of the class.
Each lab report is worth 50 pts (9x50 = 450 pts). Observing the safety regulations and conduct in the lab will be considered in grading the labs. Final grades will be calculated as follows:
Total scores (in %) within the following ranges guarantee the student at least the indicated letter grade: A, 90.0-100; B, 80.0-89.9; C, 70.0-79.9; D, 60.0-69.9; F, 0-59.9.
