Lab manual and Safety Glasses (or goggles):
The lab manual and safety glasses must be purchased at the Chemistry Club in the Chemistry Resource Room 215 JH. All students must wear approved safety glasses or goggles when in the laboratory. The Chemistry stockroom will no longer be loaning safety glasses to students. Therefore, you must purchase your own safety glasses and have them on when entering the lab. Students will not be allowed to work in the laboratory without safety glasses or a lab manual beginning the second week of classes.
Grading:
| Dimensional Analysis worksheet | 10 pts. |
| 13 Laboratory Reports @ 12 pts each | 156 pts. |
| 13 Pre-lab Quizzes @ 3 pts each | 39 pts. |
| Total | 205 pts. |
> 60% or better in lab is required to pass the course, regardless of the lecture grade.
Quizzes:
Pre-lab quizzes will be administered in lab, at the beginning of the hour. The quiz will be taken from the scheduled lab experiment and may involve a calculation. Each student is responsible for his or her own quiz. There are no make up quizzes or exceptions to the scheduled dates.
Tardiness and Absences:
It is important to come to the laboratory class on time. Pre-lab quizzes will be given during the first 10 minutes of the lab. After which, the teaching assistant and laboratory instructor will outline the salient points of the laboratory exercise and discuss safety issues. Thus, students who arrive late will miss out on these important issues and may not be able to complete the exercise on time or successfully. Further, late arriving students may be a safety hazard to themselves and to other students. Accordingly, students who arrive more than five minutes past the start of the lab class will receive a 1-point penalty on their lab grade. Students who arrive more than ten minutes past the start of the lab class will receive a 2-point penalty on their grade. No students will be admitted after 20 minutes; these students will receive a grade of zero for that experiment.
If a laboratory is missed due to an excused absence (determined by the laboratory instructor), the lab grade will be based on points earned in the other experiments. Typically, no more than one excused absence is given. A grade of “0” will be recorded for unexcused absences.
