The lab notebook should take the form of a daily log. It is o.k. for something to be crossed out. Each entry should be dated. Each page should be signed by you and by a lab mate. Your lab notebook should be a resource to yourself, so you have a record of what you did, and it should also be able to provide any reader with the information needed to understand and repeat the work.
Attendance is required at ALL labs and lectures.
If you have an emergency and cannot make it to class, I expect to be notified by phone that you will miss class. If I do not answer my phone, leave a message on my voice mail telling me the reason you will be absent. That means that after 2 unexcused absences, you will not be able to make higher than an AB, no matter what your average. It also means that if you have 7 unexcused absences, you will not pass the course. If you do miss a lab, even for an excused absence, you are responsible for making up all lab time missed and for all material covered while you were absent.
