Please see your syllabus for specific dates.

Attendance Policy All labs are mandatory. No make-up labs for any reason. Missed lab = zero (regardless of reason). Missing 3+ labs = F for course. Athletic events are NOT excused absences.

Grading Lab is graded separately than lecture! –Quizzes (45%) –Final Lab Reports (55%) Course Grading: –A = , B = 80-89, C = 70-79, D = 60-69, F = 59 and below. –Plus (+) or minus (-) grades may be awarded at the discretion of the instructor.

Accidents and Injuries Report ALL injuries to lab instructor IMMEDIATELY, no matter how minor. Be aware of hazards associated with each chemical and technique you will use in the experiment! Complete an Injury Report Form.

First Aid Eye accidents: Wash eyes in stream of water using eyewash station for 15 minutes! Chemical burns: Immediately flush the affected area with a large amount of water in the sink! Use safety shower if necessary! Thermal burns: Determine the type and extent of the burn. Take appropriate action. –1 st degree: red skin, no blisters. Immerse in cold water/apply ice. –2 nd degree: blisters. Immerse in cold water, then apply clean gauze. –3 rd degree: broken skin, tissue damage. Cover with clean gauze. Visit the Health Center.
