Students will be able to understand and execute written chemical procedures. Students will be able to properly use basic laboratory equipment. Student will be able to analyze and interpret collected data by using information provided in the lab manual and course text book. Student will have ability safely handle and dispose of chemical compounds.
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.
