OBJECTIVES:
     This course is the second half of a year long program intended to provide the student
     with a fundamental background in chemical principles. Specifically, the second
     semester has chemical equilibrium as a central theme. Sharpening the student's
     ability to explore scientific inquiry in the laboratory is also a fundamental
     component.

HONOR SYSTEM:
    I expect the University Honor System to be upheld. This means that any graded
    work must be your own effort. Group work in the laboratory requires a team effort
    to gather data, but not the calculations. You are responsible for your own report. Be
    sure you can personally justify anything you turn in.

                                             LABORATORY

    There will be two types of laboratory activity, S labs are usually performed individually and
    have laboratory skill development and reinforcement of lecture concepts as the primary
    goals. The other type of activity, the P lab, is a group project where the students must work
    as a team to solve a chemical problem.

    For the S labs there is a pre-laboratory assignment posted via Blackboard. This includes a
    short presentation about the experiment and is followed by a 5 question quiz. These
    presentations will be made available one week prior to the scheduled activity, and the quiz
    must be completed before you come to lab. Your performance on the quiz will impact the
    grade you receive on that laboratory report in the following manner:

                                   # of questions      lab report score
                                 answered correctly      adjustment

                                         0                   - 15

                                         1                   - 10

                                         2                   -5

                                         3                   -3

                                         4                    0

                                         5                    3

    Thus, if you get 3 questions correct on the pre-lab quiz and your lab report would normally
    receive an 85, the actual score will be an 82. All of the S labs counted together count as
    60% of the overall lab grade.

    There will be two team projects this semester. As with those performed in CHEM 111, the
    team will be working out the details for a laboratory experience for a future general
    chemistry class. As a team they will present one report which includes background and
    instructions for the student performing this experiment as well as information for the
    instructor running the laboratory. See details in the course pack for individual student
    responsibilities. The following chart outlines how the reports will be graded. (If QA is part
    of the project, the total will be divided by 120 to determine the final score)

           individual                                      team                                   peer

    Overall, the S labs account for 60% of the overall laboratory grade, while the P labs account
    for 40% of the overall lab grade.

           Attendance in the laboratory is mandatory. Your group depends upon your
    contribution to the projects. If you have to miss a laboratory due to an emergency you
    should inform the instructor as soon as possible, as well as your group members. Your
    group will inform you about their activities during the lab period and may decide to assign
    you make-up work, such as a library search for background material. If you miss a
    laboratory for an unexcused reason your individual grade on that project will reflect the

                                                                                                  3
absence. This way the group will not be affected, only the individual.
       You should complete as much of the work and planning of your experiments as
possible during the assigned laboratory time. No unauthorized access to the laboratory is
permitted. All experiments must be completed while the instructor or lab aide is present.


Laboratory Final

       The laboratory session will be devoted to two activities, during the last week of
classes. At the start, the class will be given a laboratory practical exam which should take
an hour to complete. Half the class will come at the scheduled start of the laboratory
period and half will come 90 minutes later. Performance on this 30 point exam will impact
the overall laboratory grade as follows:

               0 - 12              -3
              13 - 15              -2
              16 - 18              -1
              19 - 21               0
              22 - 24              +1
              25 - 27              +2
              28 - 30              +3

If your average laboratory grade is a 79 and you get 26 points on the lab final, your
lab average will be adjusted to an 81. That will then be factored into the overall
course grade.
  After you have completed the laboratory assessment, you will check a lab station
to make sure it is clean and complete.


  All experimental work is associated with potential risks, such as exposure to
hazardous chemicals and minor injuries such as cuts, burns. Every student will be
trained in basic laboratory safety and informed about personal protection and
equipment. Students will be provided information about accessing material safety
data sheets that provide information about specific chemical hazards. During the
first laboratory period of this semester, safety rules will be presented and reviewed.
In order to continue to participate in the course, the student must sign a liability
waiver, acknowledging the understanding of the risks associated with the course.


If at any time during any laboratory period the instructor feels a student’s actions
are a danger to him/herself or others, that student may be asked to leave
immediately and receive a failing grade for that experiment.
