You
are required to attend all lectures.
By school regulation, instructors will keep accurate attendance records and must report the
number of absences for each
student when midterm and final grades are turned in. Two tardiness
instances will be equated to one absence. 2% of the class grade will be attributed to attendance. Points will be deducted from the attendance grade
proportionally to the number of documented unjustified days of absence.
Unjustified absence for a time equivalent to two or more weeks of class will result in forfeiture of the attendance grade. To avoid penalty, any absence
will have to be justified beforehand or immediately after it has happened.
A
student who does not show up in a
lab cannot be included in the
corresponding lab report and therefore receives
a grade of zero for that lab. Points
will be deducted for tardiness
proportionally to the amount of time missed. Showing up after the end of lab manipulations will be equated to an absence.
A student who serves as an
official representative of the college will not be penalized with unexcused
absences when the absences result from regularly scheduled activities in which
he/she represents the college.
Regardless of the cause of the
absence, it is the responsibility of the
student to contact the instructor prior to the absence and to make arrangements to make up any work that will be missed, in a manner
acceptable to the instructor.

COURSE
DESCRIPTION, PRE/CO-REQUISITES, TOPICS, AND OBJECTIVES
This course serves as the laboratory companion of CHEM 1212
lecture. Admission in CHEM
1212L requires passing CHEM 1211L with a grade of
C or better. CHEM 1212L must be taken
simultaneously with the corresponding lecture: CHEM 1212. Any departure from this rule must be authorized by the
Head of the Science Department.
Chemistry 1212L (1 credit hour)
meets once a week for three hours. General topics include Freezing point
depression, Reaction kinetics and equilibria,
Acid-base reactions, Thermodynamics and Electrochemistry.
Chemistry 1212L appears together
with 1212 in either Area D (Science, Mathematics, & Technology) or F
(Major-Specific Courses) of your core curriculum. In Area D, the 1211/L-1212 /L
sequence may be used to meet the lab science sequence requirement for science
majors. Non-science majors may use both 1211/L and 1212/L in Area D or may take
only 1211/L and apply it in Area D as one of the lab science courses.
Objectives for this lab include
exposure, both quantitatively and qualitatively, to the various topics covered in the lecture
component. This course is designed to train
students in laboratory techniques
that are essential to understanding the chemistry concepts covered in CHEM 1212
lecture. Emphasis will be placed on laboratory techniques and experimental data collection, processing, analysis and interpretation. Critical thinking, computational
and problem solving skills as well as drawing or diagramming will also be
addressed. Topics covered include Freezing Point Depression, Kinetics, Chemical
Equilibria, Acid-Base Reactions, Thermodynamics,
Redox Reactions and Electrochemistry.
REQUIRED MATERIAL:
SCHEDULED
ACTIVITIES
The
laboratory work will include pre-labs, lab quizzes, laboratory experiments and
reports, a lab mid-term, and final exam. The lab final will be completely
comprehensive, covering topics contained in all labs.
Pre-Lab
Activities
and Quizzes
Pre-labs
and quizzes
will be done together. They will be done mostly online on WebCT. They are designed to help students gain familiarity with the concepts underlying the experiments to be conducted as well as the various techniques and procedures
involved in those experiments. Pre-labs and quizzes are to be completed before coming to the laboratory.
Otherwise a zero point grade on the relevant activity will result.
Post-Lab Reports
Each lab performed is the subject
of a report. Each lab team writes one report. Labs are due no later than
the next class day after the lab was done. Late labs will receive a
grade of zero.
TESTS.
There
will be one lab mid-term and one lab final tests. Both tests will
have equal weights.
The material covered by the mid
term will include the pre-labs, quizzes and labs performed up to that time. The
lab final test will cover all lab-related activities (pre-labs, lab quizzes,
experiments) performed during the semester.
Students enrolled in classes in
the Division of Science and Mathematics will be expected to demonstrate an understanding of subject matter
requiring higher order processing skills. The
tests will seek to assess students’ ability to understand the concepts which
govern the experiments run in the lab, as well as the data processing and
interpretation, and problem-solving skills gained. Test questions will be a combination of concept understanding
and problem-solving questions. Each test will be made of two components:
in-lab and online.
In-lab
test
questions will be a combination of multiple
choice and essay types. Instead of a mere statement of facts, a
typical multiple choice question will also include the justification of
the statement. This not only better demonstrates knowledge of the material, but
it also limits to a minimum the probability of obtaining a high grade through
picking the correct answer by mere luck.
Even though they take a
considerable amount of time to grade, essay
questions provide better insight
into student knowledge and thinking process, which allows for better
intervention to improve student knowledge quality and level when such
intervention is warranted. Typical essay questions will seek to evaluate
the ability of the student to explain, interpret, and/or apply
concepts.
Questions in the online test components will be mostly calculations, in addition to short answers,
matching and fill-in-the-blank types. The main objective of the online components will be the assessment of students’ problem solving and
experimental data processing skills.
Rather than rote memorization,
the correct answers to the questions will combine knowledge and explanation
of concepts, and /or ability to rationalize phenomena and procedures, which
are better tools to assess mastery of concepts and problem solving
procedures.
Only
compelling and verifiable reasons will be accepted in order to make up
a missed midterm test. The explanation for missing a test must be
given prior to the test, except for situations out of the student’s
control. Pre-approved missed mid-terms will be made up at final test time.
Failure to secure a permission for make-up before the
test will result in a zero for the missed test. No make-ups will be allowed for
the final test.
EVALUATION.
The laboratory grade will be
determined from the evaluation of pre-labs, lab quizzes, laboratory reports,
lab mid-term, and lab final exam.
The average grade from pre-labs and quizzes will count as one lab test on your final lab grade. The average grade from the lab reports will also have the weight
of one lab test. The mid-term and
the final exam will be the other major components. 2% of the lab grade will be
reserved to the conduct in lab. Students will be evaluated also based on the
way they follow the lab rules. 2 points will be deducted from the grade at
every violation citation.
The
lab grade will be made of the following items:
1.
Pre-labs
& Quizzes = one test
2.
Lab
Reports = one test
3.
Mid-term
test
4.
Final
test.
Overall: 4 performance items, each
carrying 24% of the total lab grade.
5. Attendance and Conduct: 4% of total lab grade
Total %: 100%
Grading
Scale & Percentage/grade conversion
Percentage Grade
90-100 % A
80-89 B
70-79 C

0-59 F
LOWER MIDTERM GRADES
If the grade of the final test is higher than the mid term
grade, the mid term grade may be dropped,
at the discretion of the instructor
and if the conduct of the student
justifies it. However the grade to be dropped must be in a position to affect
the letter grade of the lab in order to justify its removal. Moreover the
grade to be dropped must correspond to a test that was actually taken. A skipped
test does not apply.
ACCOMMODATIONS
FOR STUDENTS WITH LEARNING DISABILITIES
Special accommodations will be
provided for students with learning disabilities on a case-by-case basis. Any
student who fulfills learning disabilities conditions must get in touch with
the teacher in order to insure his/her case will be dealt with properly and in
a timely manner.
WITHDRAWAL FROM THE COURSE
If the student needs to withdraw
from this course, it should be done by the deadline date of February 29,
2012. Dropping out of the lab leads to dropping out of the class and
vice-versa. If the course is dropped by the deadline date, the student will be
awarded a grade of W. After the withdrawal date, dropping the lab leads
to a grade of WF. The course can be
dropped with a grade of “W” only under very extenuating circumstances. In this
case, the withdrawal must be approved by the instructor and the Chair of the
Science Department. Otherwise, a grade of “WF” will be awarded.
CHEM 1212L is a co-requisite of
CHEM 1212. Dropping one leads to
dropping the other.
More
information on this and other issues may be found in the current ABAC catalog
accessible at the following link: http://www.abac.edu/catalog/2011_2012/AcademicPoliciesandProcedures.pdf
It is important to notice that
even when it is done by the deadline, dropping
classes may have negative effects
on such processes as Hope scholarship
(which considers attempted instead of completed hours) or insurance (some companies require full time status for coverage).
ACADEMIC
DISHONESTY:
Academic
dishonesty
as defined in the Abraham Baldwin Catalog will
not be tolerated. Cheating, plagiarism or any other form of dishonesty is
strictly prohibited. Sanctions
will be imposed on anybody caught in
the act. The source and the beneficiary will be punished equally. Depending on the
gravity and / or frequency of misconduct, the punishment could amount to
failure in and dismissal from the class. All infractions will be dealt with
according to the procedures outlined in the Catalog. Sanctions may include a zero
on the assignment or even failure in
the class. Students are recommended to read and review this material.

ELECTRONIC
COMMUNICATION DEVICES POLICY
The use of any device which can deliver and/or
receive electronic messages will be strictly prohibited. The source and the
destination of the messages will be sanctioned equally.
EYE AND HAND
PROTECTION:
Students are required to wear eye
and hand protection at all times in the laboratory. Students not wearing
goggles and gloves in the lab will be asked to leave and no credit will be
given for that particular experiment. In requiring that students wear goggles
and gloves, the need for safety in the lab outweighs the need for comfort.
General Safety
and Laboratory Rules:
1. Be
familiar with laboratory procedures and safety precautions to be carried out
before coming to lab. If you are at all in doubt as to any procedures or safety
measures, consult with your instructor.
2. Be
aware of what is happening around you at all times.
3. Use common sense at all times
when in the lab.
4. Listen very carefully to any
safety procedures and cautionary measures discussed by your instructor. Ask questions
if you still are uncertain of any safety procedures and cautionary
measures.
5. Wear older, less valuable
clothing (preferably cotton or wool) if possible. If you must wear nicer
clothing, wear a lab safety coat. Some safety coats will be made available in
the lab.
6. Never eat or drink in the lab.
7. Wash your hands immediately
after contact with any lab chemicals. Always wash your hands before leaving the
lab.
8. Wear closed, leather shoes and
long pants or skirts (something to protect your legs).
9. Don't wear eye contacts in lab
if at all possible.
10. Tie up long hair.
11. Help look after your lab
partner and others around you.
12. Exercise special care
whenever you are using flammable chemicals.
13. Never perform unauthorized
experiments.
14. Learn the location of the
eyewash stations and safety shower.
15. THINK SAFETY AT ALL TIMES.
LEAVING THE
LABORATORY:
See
number 7 under General Safety and Lab Rules. Clean up your area before leaving.
Points will be taken off for leaving the work place dirty.
MISSED
LABS.
A missed lab can't be made up after the week when it was on schedule. A valid
reason for missing the scheduled lab must be given and accepted before a
student can make up a lab in section other than the one in which he/she is
registered. It is the responsibility of
the student to contact the instructor prior to the absence and to make arrangements to make up any work that will be missed, in a manner
acceptable to the instructor. Any missed
lab work that is not made up
will receive the grade of zero.
