CHEMISTRY 1 1 5 LAB, Fall 201 4; Section 70804 TTh: 1 1 - 1 : 50; Room NS- 336
Dr. Geetha Natarajan, Office: NS-355C; Hrs: TBA
Voice mail: (760) 744-1150 x 2508, email: ngeetha@palomar.edu (not for requesting grades)
Lab Manual: Experiments in General Chemistry, R.A.D.Wentworth, 10th Ed.
Hand Outs: Hand outs should be brought from my webpage www2.palomar.edu/users/ngeetha. MOST of the
handouts are pdf files. If you have any concerns please talk to me first.
Required Supplies: Z87 Safety goggles, TI-30x II s (non-graphing scientific calculator), pencils, ball-point
pens (non-erasable, black/blue), lab notebook with duplicates and page numbers, stapler, dish detergent, two
kitchen towels and a roll of paper towel, disposable gloves.
Guidelines, deadlines and general info:
● Students are responsible for dropping the class before the required date. Evaluative grades must be given if you surpass that
drop date. Any notation (A, B, C, D, F, FW, W or I) attached to a class will be counted as an attempt in the repeatability limit. If
students have attempted a class three times , then they will be shut out of the class when they attempt to enroll.
● Good record keeping is an invaluable skill regardless of your future profession and particularly to the scientific career
bound. Before you come to class, read the experiment and write the procedure for each experiment in the lab notebook. Bring
note book, book, and/or the required handout to each class.
● If you do not come prepared to lab, (example: no procedure outline written, no printout of handouts etc.) you will not
participate in the lab.
● When working in groups, write the name(s) of your lab partner(s) below your name and write partner in parentheses..
Record data in non-erasable ink. Never use white out. Cross out any error in data neatly (so that it is still readable like this) and
enter the correct data next to or above it.
● The data collected must be initialed and dated by me before you leave. Neglect of this responsibility will cost you all the
points for that class.
● Credit for any experiment is given only when you participate in all sections of an experiment.
● Please check with me for due date for each lab report. In order to be fair, procedure and prelab are to be turned in during the
first 5 minutes.
● In all calculations, show step-by-step solution with the formula used to get credit. Calculators cannot be shared in exams. No
caps or hats allowed during testing. You cannot leave the classroom during tests. If necessary, seating may be done by the
instructor for exams.
● Student behaviors that disrupt the class would not be tolerated. Cell phones should be turned off and put away during
class as well as exams.
● Even if you did the experiment in a group, post lab work must be your own. Any copying will result in a ‘ZERO’ for all
parties involved. Use of any unauthorized material will result in a course grade of F.
● Unless you wear safety glasses and covered shoes you will not be allowed to participate in class. Points will be
deducted if you do not sponge wipe and dry your lab bench on completion of the lab.
●
When you miss one lab, you would use it as the report that can be dropped.
After the first absence, make-up would be allowed only if 1. a message is left prior to missing class and 2. a valid written proof
showing the absence was unavoidable is brought and 3. make-up notice from storeroom manager is obtained and signed by me.
●
Three or more missing labs will result in ‘F’ grade. There will be no make up for exams.
