Advanced Laboratory II

Chemistry  4912L

Fall Semester 2006

           

Instructor:  Dr. John E. Hansen        Office Hours:  11:00 - 2:00MW,  8:00 - 12:00 T

Office:  TLC 2126;   Phone: 830-2314;   email: jhansen@westga.edu

 

Objectives

 

This is the second in a series of laboratory courses to familiarize the student with the physical basis and application of chemical measurement.  Special emphasis will be placed on instrument design, laser and optical spectroscopy, mass spectrometry, and nuclear magnetic resonance spectroscopy.  This course has been designated as a writing intensive course for the Writing Across the Curriculum Program (WAC).  This means that there is a writing component as part of this course that must be successfully completed to receive a passing grade. 

 

Learning Outcomes

 

Students will demonstrate their ability to collect, analyze, and interpret data.  Particular emphasis will be placed on the student’s ability to carry out a complete error analysis on collected data, and how that analysis affects their interpretation.  Students will also demonstrate their ability to write a laboratory report.

 

Prerequisites

 

The prerequisites for this course are Chemistry 3521 & 3522.  If you had difficulties in those courses, you will find this course particularly difficult and you will need to put forth even more study time.  NOTE:  It is an implicit requirement, and it will be assumed, that you are fluent and very comfortable with calculus.

 

 

Policies

 

1. You are responsible for all material covered and all announcements made in

    class. Absence from class does not excuse or relieve you of this responsibility.

2. Cheating will not be tolerated.  On the first occurrence it will result in a grade of zero

    for the exercise in question.  A second occurrence will result in a grade of F for the

    course.  All out of class assignments will be done in the absence of any collaboration 

    from others.  Any questions, clarifications, or requests for assistance should be directed 

    only to me.

3. No make-up exams will be given. Anyone not able to take an exam on the day 

    scheduled must contact me before the exam.

4. Your attendance at all class times is critical to your success in this course.  I reserve the

    right to withdraw you from class roles due to flagrant absences or tardiness.

5. NO CELL PHONES!!  I do not want to see them.  I do not want to hear them.  Prior to

entering the classroom, you will place your cell phones in your backpacks and leave them there until after class.  Violation of this rule will result in immediate dismissal from that day’s class, if during an exam – a grade of zero.

Grade Scale:   > 90% = A; 80 - 90% = B; 70 - 80% = C; 60 - 70% = D; < 60% = F.

 

Writing Laboratory Reports

            One of the purposes of an advanced laboratory course is to provide experience in writing scientific reports.  In accordance with the WAC requirement, Formal lab reports will under go editing and resubmission if deemed necessary.  To keep the writing load reasonable, a formal lab report is required for only four of the nine experiments.  Three others can be written in a shorter informal format with another two reports submitted as abstracts.  The detailed guidelines for these formats will be provided in class.
