Get to lab on time, so you can take the quiz and participate in the pre-lab discussion. This is a safety-related requirement. Consistent tardiness to lab will result in missed quizzes and may result in you being dropped from the course. If you miss the lab-specific safety information presented at the beginning of each lab, you may be a potential hazard to your classmates; you must talk with me before beginning your lab work. You may leave early if you have submitted your lab report(s) and/or problem set(s) and your work area is clean.

Pre-Lab Quizzes will be given weekly to ensure that you are prepared to do the experiment, and to test your understanding of the lab and/or activity from the previous week. Lab quizzes often begin promptly at the start of the period have fixed ending times, regardless of your arrival time. There are no make-ups for lab quizzes, regardless of whether or not your absence or tardiness is excused.

Lab Reports. The second half of the lab manual consists of experiments most of which involve use of chemicals and lab equipment. Late lab report submittals are not accepted.

Activity Exercises comprising the first half of our lab manual provide excellent reinforcement of concepts covered in our lecture and lab classes. Late activity exercise submittals lose 25% per week, if due to an excused absence.

Lab experiment make-ups might be possible during other lab period at Miramar: (1) if your absence is excused, (2) with my prior approval, (3) with the prior approval of the other lab instructor, and (4) only if the other class is doing the same experiment. Available make-up times may occur prior to your absence, so you must plan ahead as much as you can!

Lab Report Requirements. Lab reports and activity exercises are done by individual students, and each day. Usually, you will perform the experiment in groups, but each one of you must submit an individual lab report. Pass in the pages from the lab manual in numerical order, stapled. Write your name and the lab number on the front page of your report. Write the word "Partners:" and the names of each of your partners for the experiment on the front page below your own name. (If you perform the lab without partners, just write "no partners" beneath your name.)

Suggestions for Lab. To do well in the lab, you must prepare for each experiment. Before you walk in the door, I expect you to read the lab experiment and attempt to envision what you'll be doing. Ask questions beforehand if anything doesn't make sense! Write out the procedure in your own words, draw pictures, and think of questions for the prelab discussion. Your time spent planning for each experiment will pay off in efficiency, accuracy, and safety while you're in the lab.

Lab Partners. Typically, you will be working with a single lab partner. This may, but does not have to be the person with whom you share an equipment drawer. For some experiments, we'll work in larger groups, as specified during the pre-lab discussion. Lab groups larger than the maximum specified in the pre-lab will suffer point deductions on their lab reports.

Dress for Lab. Wear old clothes. In general, if you would be sad to see a piece of clothing or jewelry dissolve or become permanently stained, then don't wear it to lab (or wear a lab apron over it). Required clothing includes shoes with tops and safety goggles. Latex gloves and lab aprons are optional and available in the campus bookstore.

Lab Drawers ("lockers"). Groups of two students share lab equipment in a locked drawer. During check-in, you will sign a paper saying that you will return the drawer with all of the equipment in good condition at the end of the semester. Check-in is your opportunity to make sure it is all present and in good condition when you get it.

Locks. Each "locker group" must purchase a V-629 lock from the Miramar Bookstore. This provides easy access and security and is a chemistry department requirement, and it allows the lab techs to open your lockers in case of spills, fumes, etc. Locks not of the V-629 variety will be cut off.

Before you leave.
- Read the whiteboard. Check for announcements.
- Wash your hands and clean your benchtop.
- Return borrowed equipment to original location.
- Pour chemicals into the hazardous waste container.
- Don't forget to pass in your report(s).
