| Chemistry 152/152L Fall 2010 Syllabus: Lab Details | |
| Get to lab on time, so you can turn in your pre-lab
questions on time, take the quiz, and participate in the pre-lab discussion.
This is a safety-related requirement. If you miss the lab-specific safety
information presented at the beginning of each lab, you may be a potential
hazard to your classmates. If you are late, you must talk with me before
beginning your lab work. Consistent tardiness to lab will
result in you being dropped from the
course. You may leave early if you have submitted your lab report
and your work area is clean.
Pre-Lab Assignments and Quizzes. The pre-lab assignment for each experiment is due and lab quizzes begin promptly at the start of the lab period, regardless of your arrival time. These pre-lab assignments ensure that you are prepared to do the experiment, and the quizzes test your understanding of the current and previous labs. Lab Report Requirements. Lab reports are done by individual students. Usually, you will perform the experiment in groups, but each one of you must submit an individual lab report. Pass in the double-sided 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, write "no partners" beneath your name.) 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 locker. For some experiments, we'll work in larger groups, as specified during the pre-lab discussion. Lab groups larger than the specified maximum will suffer point deductions on their lab reports. Lab experiment make-ups might be possible during another lab period at Miramar: (1) if your absence is excused,and (2) with my prior approval, and (3) with the prior approval of the other lab instructor, and (4) if the other class is doing the same experiment. Without these four conditions being met, a lab make-up is impossible. Be aware that available make-up times may occur prior to your absence, so you must plan ahead as much as you can! |
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.
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. Safety Goggles. The requirement to wear safety approved goggles during lab will be enforced continuously with warnings and point deductions. You will need to be wearing your goggles whenever any student is working with chemicals or lab equipment. "Rental" goggles will cost 5% the first time; the cost will double each week. 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 technicians to open your lockers in case of spills, fumes, etc. Locks not of the V-629 variety will be cut off. Groups without V-629 locks will lose points from each lab report, starting at 5% and doubling each week. 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). |
