COURSE DESCRIPTION
CHEM 207L is a one-credit laboratory course
that introduces basic laboratory techniques, quantitative analysis, qualitative
analysis, spectrophotometric analysis, gravimetric analysis, stoichiometry, descriptive chemistry and chromatography. CHEM 207 should be taken concurrently.
This course,
along with CHEM 207, CHEM 209, and CHEM 209L will fulfill the Shepherd
University General Studies requirement for eight credits in the Life or
Physical Sciences. Specifically this course addresses the following General
Studies intended student outcomes:
2.3 Understand
cause and effect relationships
2.4 Understand
basic scientific concepts and methods
3.5 Utilize tools
such as charts, graphs, and equations to represent functional relationships and
explain their meaning.
COURSE OBJECTIVES
To learn how to take measurements with precision and accuracy.
To learn how to use laboratory equipment.
To learn how to make observations to identify chemical and physical
changes.
To learn how to use a laboratory record book to record observations
and data.
To
learn how to analyze data and report results.
TEXTBOOK
The
laboratory manual is required and is available in the bookstore.

SAFETY
The experiments have been
designed with safety as a major consideration. However, the equipment and
procedures will be unfamiliar to you and mistakes can and will happen. Be sure that you understand the hazards
associated with the equipment and reagents before starting an experiment. Do not be afraid to ask questions. SAFETY
GOGGLES OR GLASSES MUST BE WORN AT ALL TIMES.
STUDENTS MAY NEVER WORK ALONE
IN A LAB.
PREPARATION BEFORE THE LABORATORY
You will be able to work
much more efficiently in the lab if you read the lab before the experiment. Be prepared.
The time spent in preparation is time that you won't have to spend in
the lab.
ATTENDANCE POLICY
Students
are expected to attend all laboratory sessions.
Makeup labs will not be allowed without a valid written excuse. Labs that are missed with a valid excuse may
be made up at a time determined by the instructor or in the last period of the
semester. Students may NEVER work in a
lab without permission of the instructor.
ACADEMIC HONESTY
Cheating in all its forms, including plagiarism and
cheating on visual work, is considered an academic matter and will result in
automatic dismissal from the course and will be recorded on the official
transcript. Using another student’s data
for a lab that you missed will result in a zero for the lab. This dishonesty will also be reported to be
recorded on the official transcript.
LAB NOTEBOOK
All
students will need to have a bound lab notebook. Spiral bound notebooks are not
acceptable. As a preliminary exercise
for each lab you should briefly summarize what you will do in the
experiment. Your summary should include
a brief (one or two sentence) statement of the purpose of the experiment and
the type and number of measurements that you will make.
A
lab notebook is used to keep a record of the work that you do in the lab. Notebook entries should be complete enough to
allow you or someone else to recreate the work that you did in the lab. Each page should include the date and the
name of the experiment. All entries
should be clearly labeled and should have correct units.
Data
should be entered in tables whenever possible.
All tables should have a title and all columns in the table should have
titles and units. All entries in the
notebook should be neat and clearly identified.
The best way to make you notebook readable is to make constant reference
to the procedures in the instruction book.
The notebook should be signed by the instructor at the end of each
lab period. The notebook will be
graded for completeness and clarity.
REPORT SHEETS
The report sheets that are part of the
lab handout can be used as lab reports.
All parts of the report sheet should be filled out unless you are told
otherwise. Some reports include addition
questions to be answered.
The report sheets are due one week
after the completion of the experiment.
There will a 2-point deduction for per day for late reports. Even if you finish the lab procedure early it
is a good idea to stick around and finish as much of the report as
possible. The material will be fresh in
your mind and the instructor will be available for assistance.
GRADING
Reports and Unknowns 90%
Notebook 10%
There are no quizzes or tests in
this course. The grade is based on the
lab reports, notebooks and unknowns as indicated above.
FINAL GRADE
The final grade will be based on the
following scale
A 90 % to 100 %
B 80 % to
89+ %
C 70 % to
79+ %
D 60 % to
69+ %
