Attendance

Attendance at every lab is MANDATORY.

There will be NO make-up labs. You will receive a zero for every lab you do not attend, regardless of the reason.

Be on time! >10 min late, cannot perform experiment!

3+ absences = F for course

Laboratory Notebook

Check out link on course website for lab notebook requirements for each experiment.

Review Appendix C.

Pre-lab notebook pages are to be turned in before the lab begins.

In-lab notebook pages are to be turned in before leaving lab for the day.

Lab Reports

Located in lab manual.

Due the next lab period following experiment.

Late lab reports penalized 5% per day. Once graded, no other lab reports accepted!

Technique

Up to 10% of each lab report grade will be based on technique.

Grade based on: Attendance Dress code (no sandals, clothing must cover ¾ of body

while in lab!) Goggles (bring your own to avoid penalty!) Preparedness (prelab must be completed in lab notebook!) Attitude (stay positive, no matter how frustrated!) Participation (both lab partners must perform experiment!) Drawer cleanliness (all glassware must be cleaned with

soap, water, and wash acetone. Drawer must be organized before leaving!)

On time materials
