Principles of Chemistry II
Chemistry   1108 Spring  2002

Laboratory Schedule

Please note that this schedule is subject to modification.
Notebooks are due on the date listed below by 11am. If the notebook is received after 11am,
10 points will be subtracted from each lab which is due that day. Each additional work day in which notebooks are late will also result in a 10 point penalty per lab.

Laboratory Rules and Instructions

Safety - Chemistry is dangerous work for those who are unprepared. The rules set out for general chemistry laboratory are designed for the protection of you and your classmates. The penalties for coming to lab unprepared may seem harsh, but we have both your education and your bodily safety in mind. You must wear eye protection at all times. Removing your eye protection for any reason for even the shortest period of time will result in dismissal from lab and a grade of zero for that day’s work. You must wear clothing that exposes the minimum amount of skin. Long pants, sweat shirts, and sneakers (with socks) are highly recommended. Long skirts are acceptable. Tank tops, open neck blouses, sandals or shorts are not allowed. You will not be allowed into the laboratory with unacceptable attire. Also, remember that there is a fair chance that your clothing may be stained or otherwise damaged. We recommend that you wear something you can stand to lose. No food or drink is allowed in the laboratory. No radio, cassette or CD player use is allowed. Report any accidents to the graduate assistant immediately. violations of these rules will result in a grade of zero for the laboratory. Multiple offenses will result in dismissal from the course and a grade of F.

Laboratory Attendance - If you are late for lab, 10 % will be deducted from the grade for that laboratory. Laboratory attendance is required and your presence will be recorded. There will be no make-up laboratories for any reason. A grade of zero will be assigned for each laboratory missed. If you have a note from the Dean or a doctor for each specific absence, your grade for that laboratory will be determined from your average of your other labs. If you miss more than two laboratories, any additional misses will be graded as a zero.

Laboratory Procedure - You will prepare the purpose and procedure section of your notebook before you come to lab. The graduate assistant will review these sections and stamp the appropriate pages if they acceptable at the beginning of the lab. The graduate assistant will be available 15 minutes before the start of lab for this purpose. The professors or your graduate assistant will help with this if you are unsure, but you must come for help during office hours before your laboratory section meets. No student will be allowed to start the lab without purpose and procedure section approval. At the start of lab, the TA will make any additional comments when necessary. No other materials beside your notebook, a calculator and a black pen are permitted at your bench during the lab. You will then execute your procedure and record all observations in your notebook. The pages completed during the laboratory session must be stamped before the end of the period. All experiments are designed to be complete within 3 hours for 1107 and 4 hours for 1108. Therefore, the laboratory session will end promptly at the scheduled time whether you have completed the experiment or not. All work, including cleanup and laboratory notebook stamping must be done by this time. Otherwise a grade of zero will be assigned.

Notebook Stamping - The pages of your notebook containing the purpose, procedure and result sections must have a stamp on them in order for the laboratory to be graded. If you submit a notebook that does not have these stamps, you will receive a zero for that lab.

 

GENERAL INSTRUCTIONS AND SAFETY PRECAUTIONS

(The following was adapted from W. W. Porterfield and J. R. Butcher, "Introduction to the Techniques of Chemistry11, 1973, Hampden-Sydney College")

The projects are designed and time is allotted in such a fashion that they can be completed in one laboratory afternoon per week if (but only if) each afternoon's work is thoroughly and carefully planned before you report to the laboratory. Procedures and data pages should be written up in the notebook before reporting to the laboratory. Laboratory time must be spent in conducting experiments, not in deciding what to do or writing it out. If you fail to organize your time appropriately, the result will be greatly increased time in the laboratory. Planning is important.

GRADING: Your notebook will be graded. The grade is based on your notebook and formal lab reports, but is weighted somewhat differently in different projects, depending on the extent to which creativity enters the project. Careful observation of the rules for keeping the laboratory notebook will be the basis for the majority of your grade. The more it is true that successful completion of the project requires only that instructions be followed carefully, the more your grade on that project will depend specifically on the numerical result. On the other hand, the more you are required actually to design the experiment, the more the quality of that design will count toward your grade, regardless of the quantitative result obtained.

Lab Rules have been distributed and you have signed that you have read them. Paste the rules in your notebook so that you can refer to them

PLEDGED WORK: The ethics of all professionals has been a much discussed issue. The work of this laboratory must be appropriately pledged. You may receive help only from authorized sources, these include the chemistry faculty, student lab assistants, and lab manuals or reference books. When reference sources (including people) are used in any manner. Full reference to the name of the source, location of source page no., etc.), and a summary of all information obtained must appear in your laboratory notebook. In some designated experiments you may be able to get help from your assigned lab partner. Unauthorized sources include ALL students not referred to above and any notes, lab notebooks, or other materials belonging to or obtained from persons other than your assigned lab partner.

At the end of each project you must write out and sign the following pledge:

I pledge on my honor that 1) I have not received any unauthorized help on this project. 2) I have recorded all experiments that I performed in my notebook, without duplication or recopying. 3) All experiments recorded resulted from actual experimentation in the laboratory. 4)I have not altered the data in any manner so that it may correspond more closely to actual or expected values.

Signed (Your Name)

We wish to instill in you scientific and intellectual integrity. Think about how you will feel signing this if you have cheated.
