Laboratory Room: Chemistry Building, Room 270

General Laboratory Information and Policies: You must be on time for each lab meeting since the laboratories are tightly scheduled, and there is very little free time available. Two lateness’s are considered one absence. In addition, quizzes are usually scheduled for the beginning of class. Tardiness will hurt you since the lab will not be open at hours other than those scheduled. The lab will always meet in Room 270 of the Chemistry Building for the first experiment. Remember: any chemical laboratory can be a hazardous place. Read carefully the safety sheet that you will receive when you check into the laboratory. Students may not, under any circumstances, work in the laboratory without supervision. Wearing safety eyewear in the laboratory is absolutely mandatory! You will be asked to leave the lab and obtain safety eyewear if you are found without it. There will be no exception to this rule.

Missed Lab Experiments: If you miss a laboratory session, you must see Dr. Lay (Rm 520, 542-1985) IN PERSON WITHIN FIVE DAYS OF THE DATE YOU MISSED LAB to obtain an excused absence. TAs ARE NOT PERMITTED TO EXCUSE A LABORATORY ABSENCE. If one lab is missed during the semester without the permission from Dr. Lay, the student will receive a grade “WF.”

Laboratory Notebook: Everyone is required to keep and maintain a laboratory notebook. You must purchase a laboratory notebook with sewn-in binding that has the ability to make a carbon copy of each page in the book. This type of notebook is available in the University bookstore. Loose leaf and spiral bound notebooks are not allowed. Follow the directions given in lab on how such a notebook should be maintained. After each lab experiment is completed, you will be required to hand in a carbon copy of the notes and data you obtained for that experiment. The manner in which you record data and maintain your lab notebook will be graded.

Laboratory Quizzes: There will be about 10 pre-lab quizzes spaced throughout the semester. Any information that you receive concerning a particular lab is valid material for quizzes. This does not necessarily mean that the quizzes will be hard or tricky, but they will be thorough. To do well on these quizzes, be sure read and understand the experiment from your lab manual BEFORE coming to the lab session.

Laboratory Handouts: Laboratory manuals can be purchased from the Baxter Street Bookstore (360 Baxter St., Athens, GA).

Laboratory Grade Breakdown: Reports 60 %, Quizzes 25 %, and Final Exam 15 %.
