Course Description

A continuation of General Chemistry Lab I. The application of theories taught in General Chemistry II.

Purpose

The purpose of this course is to build on the experience of the first semester lab course and to use this as a foundation that will allow for increased learning during the semester. The course will continue to focus on developing skills in problems solving, scientific writing, and good scientific methodology. These skills are essential in all scientific disciplines and should benefit all science majors. An increasing emphasis will be placed on understanding of the material and interpretation of experimental results.

Goals and Assessment

To provide experience of laboratory methodology using hypothesis based investigations. Assessed by assignments, laboratory observation, and final exam.

To improve mathematical, computer, data analysis, and literature skills. Assessed by quizzes and assignments.

To improve problem solving skills. Assessed by quizzes, assignments and final exam.

To increase students ability in scientific writing and keeping a scientific workbook. Assessed by examination of notebooks, writing assignments.

To perform a short research project, including developing an appropriate method, performing precise and accurate laboratory work, interpreting and effectively communicating experimental data. Assessed by final practicum lab work and report.

To increase laboratory skills. Assessed by laboratory observation.

To increase students understanding of chemistry theory. Assessed by quizzes, assignments and final exam.

Schedule of Laboratory Work and Assignments

The work for the course is summarized in the table below. Following is an explanation of the symbols used in the table.

The numbers in the columns refer to the number of the experiment shown in the list above. A number in parenthesis means that the particular experiment may be performed at a time of your choosing, provided that you complete it by the time the post-lab discussion takes place.

Academic and Scientific Honesty

Academic and scientific honesty is expected. Academic dishonesty, including plagiarism of work, and cheating in quizzes will result in a zero grade for the work and could result in failure in the course or dismissal from the college. In submitted written work, all sources of information should be referenced and the wording either rephrased or placed within quotations. Scientific dishonesty is treated very seriously in many professions (e.g. it could lead to job dismissal, the acquittal of a guilty criminal or being ostracized by the scientific community). Examples of scientific dishonesty include copying someone else’s results, fabricating or changing results to get the expected value (note that the expected result may well be incorrect) or erasing mistakes from a notebook (they should be crossed out, initialed and a brief explanation added). Your notebook will be inspected periodically to check for scientific dishonesty. Anyone found to have been scientifically dishonest will be asked to repeat the work or given a zero grade.

Excused Absences

Students should plan to attend all laboratory periods, lectures and quizzes at the scheduled times. The only accepted reasons for absences are a death in the family, illness or official college business. You must obtain the appropriate documentation for any such absence. Please give at least a week notice, if possible, of an excusable absence so that plans can be made to reschedule.

Grading Policy

35% Performance of all experiments, preparation for laboratory, laboratory technique, understanding of the procedures and proper maintenance of the laboratory notebook.

15% Development of writing skills in preparing journal articles and computer skills in using spreadsheets for computations; demonstration of understanding of the content of the course, including chemical principles and interpretation of experimental results, as judged from the quality of written assignments.

20% Final practicum: laboratory skills, notebook maintenance and final journal article.

30% Demonstration of understanding of the content of the course, including chemical principles and interpretation of experimental results, as judged from periodic quizzes (10%) and final examination (20%)

Your grade will be determined by calculating the percentage of points you have earned out of all available points, and comparing your percentage to the standard grading scale (A= >90.00%, B=80.00-89.99%, etc.) with appropriate adjustments made for + and - grades.

The instructor reserves the right to use subjective evaluations to elevate any student’s grade at the end of the semester, but I will not do this to lower any student’s grade. I will make every effort to ensure that your final grade corresponds to the Grading System as described in the program catalog. No grades will be dropped.

Points of Order

1. Assignments are due on time, and there is a late penalty. An assignment is considered late if it is not turned in on the due date. The late penalty is ten percent per day, with a minimum grade of forty percent. When the minimum grade is assigned, the student is not entitled to the instructor's critique of the work. If the assignment is not handed in by the time the student is eligible for the minimum grade, no credit at all will be awarded.

2. Remember to bring the key to your drawer every time; there is a twenty-five cent charge for having the laboratory assistant open your drawer with the master key.

3. Safety rules must be strictly complied with. These will be discussed at the first meeting. The instructor should not have to remind you to wear your lab coat, gloves, and safety glasses in the laboratory.

4. Please keep all public areas clean. Spills should be wiped up immediately; consult an instructor as to how to do this safely. Under no circumstances should spilled chemicals be left on the balances. If solution drips down the side of a dispensing bottle, please rinse it off so that the next student is not inconvenienced or endangered.

5. Keep your own work area neat and clean. Sloppy work habits beget accidents. Two or three sheets of paper towel may be used to define a "clean" area of your work space where you may lay clean glassware.

6. The only vessel to be filled from the carboys of distilled water in the laboratory is your laboratory wash bottle, and a clear glass bottle which you may keep in your desk for the purpose of making up solutions.

7. In the interest of safety, shoes must be properly laced and long hair tied back.
