Chemistry Lab I Summer
2006
Since chemistry is a lab science, that is, it is the result of observations from experimentation in the lab, it is essential that along with a chemistry lecture, and a lab must be taught in conjunction with it. For this lab, you will need the following items:
a) Laboratory Manual: General Chemistry First Semester A locally produced lab book available in the bookstore.
b) Lab goggles: Eye protection is essential when working in a chemistry lab. If you do not wear eye glasses, you will have to either purchase or rent safety glasses. These glasses are available in the stockroom.
c) Calculator: Each lab period begins with a lab test in which a calculator will be needed. Also, you will need a calculator to perform the calculations required in the lab.
Lab Procedure
Most of the lab procedure is similar to what is spelled out in your lab manual (page V-VIII). Since this is a summer session and the labs are more condensed, there are some differences. A lab quiz will be given at the beginning of each lab period (except for the first one). During the course of the semester, there will be a total of 5 lab quizzes, each worth 50 points. Each experiment will have a prelab, a data sheet, and an unknown sheet to hand in. For each experiment, the prelab is worth 10 points, the data sheet is worth 25 points, and the unknown grade is worth 25 points. The lab will be graded on the basis of a total grade of 1000 points with the breakdown of points as follows:
Lab quizzes: 250 pts.
Data sheets: 300 pts.
Unknowns: 300 pts.
Prelabs: 100 pts.
Instructor's choice: 50 pts.
"Instructor's choice" is the part of your grade determined by the lab instructor based on whether you check out of lab properly, and the way that you conduct yourself in the lab. Your final lab grade is the sum of all the grades obtained in this lab divided by 10. Please remember that in order to pass this course, you must pass the lab section of this course separately. Passing the lab section means that you must obtain a lab grade of at least a 60.
You must be checked-in to lab before the beginning of the lab on June 6, 2005. If you fail to do so, you will be dropped from the course. Additionally, please remember that the first thing we do in lab is check-in to the lab. Once you check-in, you are responsible for all the equipment in your desk. If you need to drop the course or withdraw from the university, you must check-out of the lab. Failure to check-out will result in the imposition of a $15.00 fine.
Makeups If you miss an experiment, it must be made up as soon as possible. During the summer, makeups are very difficult to arrange. Please try to avoid missing an experiment. It is the responsibility of the student to arrange a time for the makeup. Makeups, or excused absences are granted at the discretion of the instructor. Do not assume you will be allowed to make up an experiment without a legitimate excuse.
