Lab Safety:

• ABSOLUTELY NO HORSE PLAY!
• Safety goggles or glasses with side protection must been worn in the lab at all times.
• Protective footwear is mandatory (closed toe). No open-toed slippers or sandals.
• You will not be allowed to work in the lab without adequate eye protection and proper footwear.
• You must supply your own lab gloves.

General Information:

• Pre-lab meetings (30 minutes): Be on time for every lab meeting. At the beginning of every lab class your TA will go over important concepts and experimental techniques as well as and special safety precautions that you need to be aware of.
• You will be issued a microscale lab kit at the beginning of the semester. It is your responsibility to ensure that all components of the kit are clean, present, and accounted for at the end of the semester.
• You will need a hard-covered, bound notebook -- perhaps two, depending on your TA.

Make-up Lab:

None. There will be no unexcused absences. The lowest experiment written-up and quiz grade will be dropped in determining your final grade.

Grades:

Your final grade will be based on your:

• Level of preparedness for each lab experiment.

• General Lab performance.

• Ability to work independently.

• Ability to work in a safe manner.

• Experimental results.

• Lab written-ups.

• Quiz scores, and

• TA's evaluation.

The general breakdown will be:

• Lab Report 50%

• Quizzes: 20%

• Final Quiz *: 20%

• TA evaluation: 10%
