IX.         ADDITIONAL READINGS:

             REQUIRED:   none.

             SUGGESTED:   none

X.         METHODS OF INSTRUCTION and LEARNING:

Lectures, problem solving and board work, Excel computer applications, laboratory unknowns, laboratory notebook writing and tests.

XIA.      REQUIREMENTS OF STUDENTS: Classroom attendance, laboratory unknowns and notebook keeping,  reading assigned material and doing assigned problems, participation at chalkboard or computer, test performance and use of spreadsheets and other computer activities.

            HOMEWORK ASSIGNMENTS: Homework problems will be assigned from the textbook.   These are for your benefit and will not be collected for grading.   If they are not done regularly as they are assigned, you will find examinations much more difficult.   If you have questions, please ask them in class or consult your instructor for help.

XIB.      MEANS OF EVALUATION:

 XIF.      ATTENDANCE POLICY: Daily participation is required.   Attendance is considered a measure of the student's interest and effort.  Make an effort to be present every day and on time.  Grades will not be lowered directly as a result of absence.   Students are responsible for material presented in class whether they are present or not.  Changes in this syllabus announced in class will take priority over what is printed in this document.  In the past syllabus changes have only been for test dates. 

XIG.      COMPUTERS:  Computers will be used in the class primarily for utilizing spreadsheets. It is anticipated that tests will require computer spreadsheets.   There will be a quantitative analysis (Stoichiometry) question on each exam.

XII.        CLINICAL/LABORATORY/FIELD-BASED EXPERIENCES:

            This course requires laboratory participation, proper safety precautions, proper disposal of chemical wastes and quantitative determination of unknowns.

The laboratory portion of this course is very important and also a time-consuming part of the course.   In addition to the scheduled laboratory periods, the laboratory will be open 8:00-12:00 and 1:30-5:00. Monday, Wednesday and Thursday.  You will need to find times in addition to your regularly scheduled lab period when you can weigh samples, clean equipment, cool samples, and do much of the general preparation for laboratory.   The amount of time required will depend on how well you can organize your time and on the number of times you have to start an experiment over because of carelessness or accidents.   Learning to be efficient is one of the goals of the laboratory work.

SAFETY GLASSES ARE REQUIRED when preparing solutions or during other hazardous activties. FAILURE TO OBSERVE THIS STATE LAW MAY RESULT IN YOU BEING ASKED TO LEAVE THE LABORATORY.

You must dispose of chemicals according to proper procedures given for each laboratory

You must wear proper footwear; ie. your feet are to be covered.

Also there is to be no smoking and no eating or drinking in the laboratory or balance room at any time.
The section of the text on Laboratory Safety and Safety Rules begins on p. 52. You are expected observe these rules at all times.  You are also expected to leave your work area, balance, and the areas you must share with others clean and orderly when you leave the laboratory for more than a few minutes.  You will be dismissed from the laboratory for the day for any safety or disposal violations.  Three violations and you fail the laboratory and class.

 All experiments are to be performed individually and independently except when specifically directed to work in groups.

LABORATORY NOTEBOOK:

All experimental data must be entered directly into a permanently bound notebook.   Any loose pieces of paper used to record data will be collected and destroyed.   Under no circumstances are any pages to be tom out of the notebook.  

Reports are due in F 215 at the time given in the laboratory schedule.   Results submitted after this date will be graded down 10 points for each week or portion of a week for which they are late.   Miscalculated results will be returned to the student for correction and the grade will be reduced by 10 points.   This will apply to decimal errors as well as other types of mistakes.   Corrected results must be resubmitted within one week of the time they are returned.  

LABORATORY SCHEDULE:  

            Experiments:   37F-4 The Determination of Iron                              due Feb. 1 

                                  37J-3 The Potentiometric Determination of Solute Species in a Carbonate

                                  37J-2 Potentiometric Titration of Chloride and Iodide in a Mixture
                             
    37N-4 The Spectrophotometric Determination of pH

                                  37N-2 The Determination of Iron in a Natural Water

           Other Due dates for experiments are March 2  and April 25

XIV.      HONOR CODE:  Each student is expected to abide by the TWC Honor Code, particularly on examinations and written reports.   You will be expected to sign a pledge for each exam.   Specifically, you will not cheat in any manner before or during the exam.  Please review the Honor Code in the “Tennessee Wesleyan College Student Handbook & Calendar”.
