Labs 90%

Final Exam 10%

An accurate record of laboratory work is to be kept in the lab notebook. An adequate record includes a brief introduction to the experiment, the procedure, data and observations, calculations and conclusions. How to do this is discussed on pages 16-24 of the lab manual. We put the procedure and observations side-by-side, as shown on page 24. It is in your best interest to make your notebook as complete as possible as 1) you will be graded on it, and 2) you will be allowed to use your laboratory notebook to help complete the final exam in this course.

Handouts for each lab project are provided on the web at

spectrum.troyst.edu/~cking/Organic 1 Labs/OrganicILabs.htm.

These contain a data table to be filled in, calculations to be done, and questions to be answered after doing the lab. Before coming to lab, you should enter in your lab book the following:

1) the title and introduction to the lab experiment

2) physical properties in the data table. (Copy the data table from the lab handout to your lab notebook and fill it in.)

3) the procedure

The physical properties needed for completing the data tables are found in handbooks that are located in the Natural Science Center (McCall 215) and in the organic chemistry lab. Each week, the instructor will check to see that the above items have been entered in the notebook, and that the observations, calculations, and a conclusion have been entered for the previous week’s project. Failure to have this done on arrival at class will result in loss of points.

Each pair of students will prepare one typed lab report at the end of the experiment. If the experiment takes more than one period, then the report is written up and turned in after the entire experiment is finished. Lab reports are due the period after the experiment is completed. The lab report consists of just filling in the data sheets. The sheets are provided on the web in Microsoft Word format. Chemical structures should be drawn using IsisDraw or ChemDraw, free chemical drawing programs available on the internet. A CD containing the program may be borrowed from the instructor.

You will loose one letter grade for each lab that is missed. Makeup labs are NOT available, except in other lab sections meeting that same week.

Laboratory Safety: The chemistry lab can be a dangerous place if certain safety rules are not followed. In light of this we will require each student abides by certain safety policies and procedures when working in the chemistry lab. Failure to comply with these procedures will result in the student being asked to leave the laboratory and being assigned a “0” on the lab. You will be required to wear departmental approved safety goggles, long pants, and closed-toed shoes at all times when working in the lab. This means that on lab days you must plan ahead to assure you will not be in violation of laboratory dress-code.

Resources: Computers are available in McCartha 119, and in the library. The Natural Science Center (McCall 215) has tutors who can help with homework, etc.

Pregnancy: Women who become pregnant must either a) drop the lab (a grade of “incomplete” may be given), or b) obtain a written statement from a doctor recommending that they be allowed to complete the course. We will work with you on this.

Disabilities: Students whose disabilities fall within the “Americans with Disabilities Act” should inform me as soon as possible of any special needs. Students with a learning disability should inform me, preferably after contacting the Office of Adaptive Needs Program (Trojan Center 215, 670-3221). Various accommodations are available through the Adaptive Needs Program.

Posting of Grades: We will not provide grade information over the phone or via e-mail. If you have any questions or concerns about your grade please fell free to come by in person and we will discuss your grade in detail with you.

The Natural Science Center (McCall 215) has tutors who can help with homework, etc.
