Students are responsible
for safety and for the stewardship of the laboratory.Students
are expected to read the laboratory manual before coming to the lab session
and they should be familiar with the techniques and precautions necessary
for safe performance of the experiment. During the first laboratory session,
you will be afforded the opportunity to choose a laboratory partner and
a workstation; please maintain these choices for the duration of the semester
so that chemical hygiene responsibilities are consistently distributed.
There are fifteen
laboratory sessions scheduled for this semester.Each
student is expected to attend all fifteen laboratory sessions.Any
absence that is not documented as excused will result in a score of zero;
dropping the single, lowest experiment report grade will be employed to
correct an excused absence.Performance
of all fifteen lab exercises as indicated by submission of all fifteen
experiment reports will result in bonus points.Three
absences will result in a failing grade even if documented as excused.
Students are to document
all of the required laboratory activities as indicated by the laboratory
schedule in a LABORATORY NOTEBOOK.Its
submission for grading is strictly due on the Friday before the
last scheduled laboratory session [The instructor will attempt
to grade the laboratory notebooks weekly during the laboratory session.].The
notebook must be permanently bound and it probably should
have at least twenty-five pages.Every
page should be numbered upon its use; and a table of contents should be
constructed.The last page of each
lab exercise recorded in the lab notebook should be dated and signed by
the student.Each page is to be TITLED
with the name of the experiment.Prior
to the performance of the lab activity, an ABSTRACT is to be written
that describes the purpose, goal, objective, and significance of the experiment.An
INTRODUCTION
is to be included that supplies a background on the theoretical and experimental
models necessary for understanding the lab activity; this can include the
instructor’s pre-lab lecture.During
the lab exercise, the experimental PROCEDURE is to be documented
in a fashion that clearly indicates the methods used and that could be
used to repeat the experiment in the absence of the lab textbook.DATA
AND INTERPRETATION of data is the most important section; your results
are the fruit of your labor.The
report sheet from the lab textbook can be employed by taping it onto a
permanently bound page in the lab notebook.You
lab notebook is your scratchpad for showing all your CALCULATIONS.A
CONCLUSION that answers the question asked in the abstract is a requirement.If
authored/edited/commercial printed materials are employed for the accomplishment
of the lab activity, they must be REFERENCED by author name, title,
edition number, publisher, location of publisher, year of publication,
and pages used.Your lab team is
to be indicated in an ACKNOWLEDGMENT section through your indicating
the nature and quality of their assistance.WITNESS
signature by the instructor before leaving the lab session dedicated to
that lab exercise is the final addition to the entry for each experiment.Each
of the boldfaced, capitalized sections will be worth six (6) points
for the entry graded.
ASSESSMENT:
Notebook
(one experiment will be chosen at random for grading):60
points
Report
(due on or before the Friday following lab session
dedicated to experiment):10 points
each
Safety
(comments on accidents/safety incidents missing from Acknowledgment section
in
the laboratory notebook will result in the deduction of safety points;
violations will
also
result in deductions):20
points each
Bonus points are available
if you can provide the instructor current, documented, properly referenced
descriptions of proper disposal methods [Statements like ‘follow local,
state, and federal guidelines’ or lab manual suggestions will not be considered
for bonus points.] for materials used/generated in the laboratory exercise.Three
(3) percentage points is the maximum that can be accumulated at one point
each.

Chem 1361 Syllabus
CHEM 1361:GENERAL CHEMISTRY LABORATORY I
THE COURSE DESCRIBED BELOW IS A LABORATORY COURSE WHICH ATTEMPTS
TO INTEGRATE LABORATORY METHODOLOGY AND TECHNIQUE WITH CONCEPTUAL ASPECTS
OF CHEMISTRY.THIS COURSE AS DESIGNED ASSUMES THAT THE STUDENT HAS BEEN
EXPOSED TO CHEMISTRY THROUGH PREREQUISITE OR CONCURRENT ENROLLMENT IN GENERAL
CHEMISTRY I (CHEM 1364).
PLEASE CONTACT THE OFFICE OF MULTI-CULTURAL AND DISABLED SERVICES
IF YOU FEEL YOU NEED SPECIAL ACCOMMODATIONS.THE SAME ACADEMIC STANDARDS
ARE APPLIED TO ALL STUDENTS ENROLLED IN GENERAL CHEMISTRY LABORATORY.
CHEM 1364 is the first semester of a two-semester course in general
chemistry.Chemistry is considered a central, core course to the sciences
and related disciplines.This course centers on the introduction of laboratory
techniques necessary for the analysis and study of matter.Concurrent enrollment
should include General Chemistry I (CHEM 1364).Satisfactory credit must
be earned in both lecture and the laboratory components before formal credit
is granted for either.General Chemistry I (CHEM 1364) and General Chemistry
Laboratory I (CHEM 1361) constitute a five-credit hour lecture-laboratory
course that satisfies the physical science component for general education
and that serves as the beginning course for the major or the minor degree
program in chemistry.
Students have the opportunity to gain experience from a number of techniques
illustrated in the laboratory exercises.Traditional and common techniques
form the central core of activities, but application of computers is frequented
in an attempt to enhance the introduction of modern data analysis techniques.A
broader view of chemistry is encouraged through invitation of laboratory
students to departmental and university seminars and professional meetings.Students
have the responsibility to avail themselves of the opportunities to broaden
themselves by utilizing available computer technology such as internet
access and tutorial software and by employing the traditional office visit.
