We recommend you do not wear shorts. The grading key on page 2 of the laboraotry booklet is typical. A revised scoring scheme will be posted soon. If a student with an excused absence misses the lab, an adjustment will be made in grading of the pre-lab and the report associated with that experiment. There is no way to make up missed laboratory time.
Illness is excused.
If you are ill, see your physician or the local Health Service for treatment. A note from your roommate is not considered as a valid excuse. Such things as studying or oversleeping won't do. For the Qualitative Analysis experiments You will need to use a lab notebook that is provided by the instructor. You are responsible for maintaining this notebook in legible and easy to follow shape.
