This information sheet is subject to change. You will be
notified in class if updates are available. You will not be given
a new "hard copy". It is your responsibility to review the
changes "on line" and print a copy for your own use.
Please check the my "NEWS PAGE" and links below before each lab period in order to obtain reminders and possible experimental procedure updates.
A list of and schedule for experiments to be performed (including tests) is available at the link Laboratory Schedule. Each student is required to print this list and bring it to class in the lab notebook.
Before you leave the laboratory, I will want to check your lab station to insure that it is left presentable for the following class. I will also want to check your raw data and possibly your preliminary calculations and results. Failure to receive my approval before leaving will result in a grade penalty.
The type of report expected for each experiment will be
for each experiment. Reports are to be typed or
hand written in ink. Information is to be presented on
of pages only. Multiple pages are to be stapled in the
left-hand corner (do not fold). Place in the upper
hand corner your name, the course and section
and the name(s) of your lab partner.
may work in groups in the laboratory, with the exception of common
reports are to be completed independently. Reports are to be
in the lab period following the completion of the experiment. I will
be responsible for reports that are turned in out of sequence or at
than the scheduled times.
Each report will have FOUR main elements (unless otherwise indicated). These elements are headed as
Reports submitted late, if accepted by me, will receive a grade
penalty. A written excuse must accompany any late report.
Each student is to maintain a notebook for data entry. The
notebook is to have non-removable pages. Each student shall
an outline summary of the experimental procedure in this notebook. The
outline of the procedure must be completed prior to the laboratory
Failure to maintain a proper notebook will result in a grade penalty.
IV. SUPPLEMENTAL MATERIALSIn addition to normal letter size stationary and a notebook, you
need graph paper (linear) and a small French curve. These items are
available at the SLU Bookstore or other office supply locations.
I. Raw data (Table where appropriate)
II. Sample calculation (With all units shown)
III. Results (Table where appropriate)
IV. Discussion (Errors, confidence in results, answers to questions, etc.)
You will need to have access to a "PC" that has MS Excel software and a printer. You will need to use the data collection/manipulation program "Logger Pro". You should bring a blank CDR to class so that you can obtain a free copy of this program. If you do not have your own personal computer, the computer lab in Pursley Hall has machines that have these capabilities.
A midterm exam and a final exam will be given as indicated in the
laboratory schedule. If you miss an exam and your absence is excused, a
comprehensive makeup will be administered. Quizzes on the experimental
procedure, symbols, oxidation numbers, formula writing, and equation
may also be given. NOTE: The decision to excuse
absence is left to the instructor (the exception being administrative
If you miss the final exam, and you do not notify me before the last
day that grades are due, you will receive a grade of zero for that
You may not leave the testing room before the completion of your test unless you obtain permission. Permission will only be granted in case of certain emergency situations. Students who leave without permission will be required to turn in their tests regardless of the state of completion.
Please note that your final exam will be at the same time and place as the pre-lab lecture and on the date indicated in the laboratory schedule (not the week of final exams). You will need a type "F" scan form for each exam. In addition to the written tests, there will be practicums (mid term and final) designed to test hands on performance in lab.
If you miss a scheduled make-up exam, you will receive a grade
of zero on that exam.
The grade for the course is determined by the grades on the exams,
quizzes, notebooks, and laboratory reports. The final grade is
by the percentage of total points as follows:
90 - 100% A
80 - 89% B
70 -79% C
60 -69% D
0 - 59% F
Final course grades will be posted on line only to be
Graded work (reports, tests, quizzes) will be returned to the student as soon as possible. It is the responsibility of the student to retain all graded work in their possession until course grades are finalized at the end of the semester. In the event of a grade dispute, the student may be required to surrender all graded work for grade verification.
The regulations of the university will be followed. In case of absence, a written excuse must be presented to me. The number of absences will be considered in determining borderline grades. Students having more than one (1) unexcused absences will not be eligible for extra credit, bonuses, and grade adjustment (curving).
Attendance at the first class meeting is mandatory. It is at this time that important safety information is presented and verified through the safety quiz. Experiments cannot be performed until this is completed. It may be necessary for a student to drop the class if the first meeting is missed.
It is extremely important that one not miss laboratories and
lectures. If one misses a lab lecture/lab, the work must be done to
credit. This includes both the experimental procedures and the lab
One must attend the lab lecture/lab of another section. The lab
will have to be made up the same week. You must contact me immediately
to make arrangements. If you complete the lab with another class and a
different instructor, you will need to have that instructor initial
laboratory data sheet. That data sheet or a copy must be
with your lab report. Failure to make up the lab lecture/lab will
in a grade penalty. This applies also to absences as a result of
attendance at university sanctioned events. Arrangements to make up foreseeable absences must be made no later than the week before the foreseeable absence or as soon as possible if the absence is not foreseen. Any delay in contacting me to arrange a make-up may result in failure to receive credit for the missed lab(s). More than one absence may

There will always be a lecture preceding the lab. At this time, the high points of the experiment are discussed, possible problematic areas are presented and pertinent safety concepts are reviewed with the class. (It should be noted that no safety discussion can be all inclusive.) If you are tardy and miss a substantial part of the lecture, you will not be allowed to participate in the lab (the experiment). If this is the case, your tardy will be counted as an absence. You will be required to do a make-up.
For your safety and the safety of others, you must be prepared for lab. Proper preparation includes reading the introductory material, reading the procedure, preparing an outline of the procedure. If you come to lab unprepared you will not be allowed to participate in the lab (the experiment). If you are asked to leave because of lack of preparation, you will be counted absent and you will be required to do a make-up.
All absences (tardies) will require the presentation of a written excuse. NOTE: The decision to excuse an absence is left to the instructor (the exception being administrative approval).
VIII. DISASTER RECOVERY PLAN:
In the event of an official university closure during your scheduled lab, we will attempt to reschedule the experiments and use a discretionary day during the semester. If that is not possible, your instructor will provide you with an out-of-class activity that will substitute for the missed lab. Check moodle, and with your instructor, as soon as possible after the closure, to find out how the missed lab will be handled.
VIX. EXTRA CREDIT:
An optional 15 point extra credit assignment may be made available
near the end of the semester. Students having any absences,
have not been excused, are not eligible.
Each student must follow all the safety rules. Safety
must be worn at all times in the laboratory. Failure to follow the safety rules will
result in grade penalty or being dropped from the class.
You will not be allowed to attend lab if you do not have proper lab attire as indicated in your safety handout. If you are asked to leave because of lack of proper attire, you will be counted absent and you will be required to do a make-up.
The Safety Handbook of the Department of Chemistry and Physics can be viewed from a the link on my main web page under the heading of Safety Information. The specific information for this class is listed in back of your Laboratory Manual.
XI. CLASSROOM DECORUM:
It is University policy that the classroom is not a place for
and that students are not to bring their family members for day care or
Free discussion, inquiry, and expression is encouraged in
class. Classroom behavior that interferes with either (a)
instructor's ability to conduct the class or (b) the ability of
to benefit from the instruction is not acceptable. Examples may
routinely entering class late or departing early; use of beepers,
telephones, or other electronic devices; repeatedly talking in class
being recognized; talking while others are speaking; or arguing in a
that is perceived as "crossing the civility line." In the event
a situation where a student legitimately needs to carry a
telephone to class, prior notice and approval of the instructor is
Classroom behavior which is deemed inappropriate and cannot be resolved
by the student and the faculty member may be referred to the Office of
Judicial Affairs for administrative or disciplinary review as per the
of Student Conduct which may be found
XII. THE ADA:
If you are a qualified student with a disability seeking accommodations
under the Americans with Disabilities Act, you are required to
with the Office of Disability Services, Room 203, Student Union.
No accommodations will be granted without documentation from the Office
of Disability Services.
XIII. E-MAIL POLICY:
The University policy concerning e-mail will be
Please check your Webmail daily. Only Southeastern's e-mail
will be used for official correspondence. Messages from other
your officially assigned e-mail address may not receive a response.
of the university will be followed in order to provide an
is conducive to learning.
XIV. ACADEMIC INTEGRITY:
Students are expected to maintain the
of academic integrity. Behavior that violates these standards is not
acceptable. Examples are the use of unauthorized material,
communication with fellow students during an examination, attempting to
benefit from the work of another student and similar behavior that
defeats the intent of an examination or other class work. Cheating on
examinations, plagiarism, improper acknowledgments of sources in
essays and the use of a single essay of paper in more than one course
without permission are considered very serious offenses and shall be
grounds for disciplinary action as outlined in the current General Catalog.
