LABORATORY MANUAL: College Publication - A copy of the laboratory manual is
available on Moodle. Download and print each experiment as you need them, each week.
COURSE CONTENT:
Basic chemistry laboratory safety
Basic chemistry laboratory techniques
Experiments that emphasize the topics contained in General Chemistry I. A detailed list of
experiments is found on the CHM-141 Lab Schedule (last page).
Data collection, data analyses and graphical representation of data and/or results
Use of the factor label method/dimensional analysis for problem solutions.
Laboratory report writing
OTHER REQUIREMENTS:
Safety goggles or safety glasses are required and may be purchased at the B.C.C. bookstore or
at a hardware store.
A scientific or graphing calculator is required.
GRADING POLICY
Instructor’s Grading Policy:
Each instructor will distribute the grading policy for each section at the first class meeting.
General Guidelines:
4
1. Laboratory Reports (prelab/quizzes, data sheets/graphs, postlab and format) . . . . 70 %**
2. Examinations (one or two midterms and a comprehensive final) . . . . . . . . . . . . . .30 %**
3. Safety Violations …………………………………………………..………minus points**
**Subject to the instructor's discretion
There will be no make-up labs or examinations except in certain special circumstances at the
instructor's discretion. Even in those cases all make-up situations must be resolved within a
week of the missed class. Any missed lab or examination will be assigned a grade of zero.
Students found cheating will be dealt with appropriately. Cheating includes using the data,
prelabs or postlabs of another student past or present. It also includes using unauthorized
formula sheets of any kind during an examination.
Please read The Bergen Community College Statement on academic integrity as found
in the college catalog and Student Handbook.
DATA RECORDING AND LABORATORY REPORT FORMAT:
1. Data is to be recorded directly onto data sheets.
NO SCRATCH PAPER.
2. Use blue or black ink to record all data.
NO WHITE-OUT.
If a mistake is made in recording data, neatly cross out mistake and write the correct data
nearby.
3. Data sheets must be signed and dated by the instructor before the end of the lab period.
4. Each person is required to perform his/her own lab work. Individual unknowns must be
obtained from the instructor and evaluated. Students will be informed when there is a need
to work with a partner.
5. Laboratory reports are due no later than one week after the completion of the experiment
and must be submitted at the beginning of the lab period in which it is due.
Lateness in submission may result in penalty points at the discretion of the instructor.
6. LAB REPORT CONTENT:
Follow the following order with regard to organization of lab report pages.
Handwritten reports are acceptable. However, graphing is to be done using Excel.
Staple all pages together.
1. Cover page: title of experiment, student name, instructor name and date (optional)
2. Data sheets (instructor initialed and dated) with supporting calculations.
Sample calculations must be clearly shown.
3. Graphs of experimental results if part of the experiment. Use Excel for graphs.
4. Post lab exercises and any post lab graphs. Use Excel for graphs.
5. Concluding/summary paragraph. In a short paragraph (approximately ten sentences)
state the objectives of the experiment and explain whether the data recorded and the
analyses of the data support the expected objectives. If the experimental objectives
were not met explain the source of errors.

ATTENDANCE POLICY:
Attendance at laboratory sessions is mandatory. Students are expected to report to lab on time,
if not a few minutes early. The pre-lab presentations/directions by the instructor for the proper
and safe performance of the experiment are critical to conducting each experiment correctly. It
has been found that students who miss some or all of this presentation usually perform their
experiments poorly. Keep in mind, it is the instructor's discretion as to when it is too late for a
student to safely and successfully complete an experiment.
OTHER POLICIES:
Electronic Devices:
The use of portable electronic devices such as pagers and cell phones is not permitted while
laboratory is in session. Please silence these devices before entering the laboratory.
Code of Student Conduct:
Students are encouraged to read, understand and follow the rules and standards of conduct as
explained in the Student Handbook. The Student Handbook is available in the Office of Student
Life and on the BCC website.
STUDENT SUPPORT SERVICES:
The General Chemistry support class, CHM-142, is recommended for students experiencing
difficulty with chemistry-related arithmetic and algebraic problem solving. Late registration for
this 1 credit hour class is allowed and encouraged.
Additionally, The STEM Learning Center in Room S-315 and the Tutoring Center (L-125)
provide student support in chemistry, math and other sciences.
Faculty office hours may be a productive vehicle for assistance in understanding the course
material.
The BCC Library provides extensive support services for student research.
SERVICES FOR STUDENTS WITH DISABILITIES
Bergen Community College aims to create inclusive learning environments where all students
have maximum opportunities for success. Any student who feels he or she may need an
accommodation based on the impact of a disability should contact the Office of Specialized
Services at 201-612-5269 or via email at ossinfo@bergen.edu for assistance.
FACULTY ABSENCE PROCEDURE:
A daily listing of cancelled classes will appear in a glass case near the registration area on the
first floor. Another such listing will appear in a glass case in Ender Hall. Students can consult
these cases before going to class. Cancelled classes are also listed under class cancellations at
bottom of the BCC website page. Under no circumstances are notices regarding class
cancellations taped to classroom doors binding.
If students find a class cancelled which has not been listed, they should report this to the
Divisional Dean’s Office, A-304 or the Evening Office C107.
