CHEMISTRY LABORATORY 145-B2

Spring, 2002 Thursday, 8:00-10:52 PM, 305 Ottensman Hall Instructor: Dr. Sundin Office: 311 Ottensman Hall Phone 342-1015 Syllabus

Introduction: Chemistry 145 is a one semester course in general chemistry for students planning on majoring in engineering . The prerequisites for Chemistry 145 are: at least one year of high school chemistry with a grade of "A" or "B" or a grade of "C" or better in Chemistry Chemistry 102, Chemistry 105, or Chemistry 114; a grade of "C" or better in Mathematics 245 or concurrent enrollment in Mathematics 253 or 264; and concurrent enrollment in English 113. Chemistry 145 and Chemistry 105 or 124 cannot both be counted toward graduation.

In the chemistry laboratory you will have the opportunity to see firsthand some of the relationships discussed in lecture as well as to become familiar with some of the laboratory practices and techniques that are used in chemistry. You will also be able to directly observe the chemical properties of a variety of substances.

Successful completion of the experiments during the laboratory period will require some previous planning. You should read the experiment, review basic concepts, and make a plan for the day before the laboratory period. A listing of the experiments is given in the syllabus. For some experiments, there are links to other Web pages which include descriptions, animations, and movies of particular techniques. Note: due to licensing restrictions, many of the movies are only available in the Chemistry Computer Lab, Ottensman 301. (Due to safety considerations, there are no make-up or open labs for completing experiments!)

Laboratory Textbook: The experiments are from the Chem 145 Lab manual, (green cover), UW-P Chemistry Faculty, etc. Manuals will be handed out in the laboratory and you will be billed for the full amount of the manual through the cashier's office. Additional experiments, revised experiments, and prelabs, will also be distributed in lecture or lab. If you miss a class period or are late, it is your responsibility to be sure that you obtain any such additional experiment handouts. It is expected that you will have read the experiment before coming to lab.

Supplementary Materials: Splash proof Safety Goggles (University Bookstore, Ullsvik Center) and a simple scientific calculator (exponents and logarithms).

Grade:		Prelab		20%	
		Reports		30%
		Quiz		30%
		Technique	 20%
Grade Scale:	A       	9.0 - 10.0
		B       	8.0 - 8.9
		C       	7.0 - 7.9
		D       	6.0 - 6.9
		F       	5.9 or less
Prelab: Successful completion of the experiments during the laboratory period will require some previous planning. In addition to reviewing the experimental procedures and background textual materials, you will have to complete, and turn in, a brief "prelab" for most experiments. This will not only increase your success in the lab, but also increase safety. Selected "prelabs' will be graded. While parts of the "prelab" will be graded for accuracy, some parts will not have a "right" answer, or the "right" answer will not be apparent until after completion of the experiment. In these latter cases, they will be graded based on the effort extended and the thoughtfulness of the answer.

Reports: Detailed postlab reports on selected experiments will be due at the end of the lab period. Late reports will not be accepted. Reports will be graded on the accuracy of the measurements and calculations and on the clarity and completeness of the observations and the logic and clarity of the explanations.

Quizzes: The quizzes will assess your knowledge and understanding of the techniques and chemistry of the experiments. You are, of course, expected to know what was done in an experiment, why it was done, what was observed, and the interpretations of the observations. Quizzes will cover that day's experiment as well as previous experiments.

Technique: The instructor will make a subjective judgement which will include: your preparation for the experiments; your ability to work independently; your participation; your observance of lab safety; your practice of lab housekeeping; etc.

Absence Policy: A laboratory that is missed will result in a lowering of your grade because all prelabs, reports, and quizzes that are not turned in when due will count as a zero. Each laboratory period will start with a short quiz and/or demonstration of various laboratory techniques and safety information. A quiz missed due to absence will count as zero. Make-up quizzes are not given. Your overall laboratory average will count for 15% of your course grade. However, a course rule is: "Unexcused absences from 2 labs will result in a failing course grade."

For safety, pedagogical, and/or efficiency purposes, some activities will have to be completed before admission into the laboratory. When a student is not admitted into the laboratory for failure to turn in the "prelab", it will count as an unexcused absence.

Late papers: Late reports will not be accepted.

Drawer, bench, and sink: You are responsible for the equipment in your drawer. Record your lock combination in a safe place. Failure to lock your drawer or if you forget or lose your combination will result in a lowering of your technique grade.

You are also responsible for the cleanliness of your general laboratory area. House equipment should be returned and waste chemicals and papers disposed of in the proper containers (watch labels on the waste chemicals containers!). Water on the bench top should also be sponged up. Failure to follow proper housekeeping procedures will result in a lowering of your technique grade.

Safety: Following all safety rules (common sense) is paramount for the safety of everyone. Failure to follow the safety rules will result in a lowering of the technique grade. Blatant disregard for safety will result in expulsion from lab for the remainder of the semester and an automatic lab grade for the semester of zero.

Disabilities: Please contact me right away if you have any disabilities so that appropriate accommodations may be made.

Academic Misconduct: Academic misconduct (pages 169-170) will be adjudicated using the procedures outlined in the 2001-2002 UW-P Student Handbook and Personal Planner (pages 170-177).
