Grading:
Lab Reports (20%)--Pages 5-14 in your text describe a format for notebooks. You will use this format for your reports; you will receive a separate handout on the format for your laboratory notebook. Lab reports are due one week after the completion date of the experiment. Except under extraordinary circumstances and only by special arrangement with your teaching assistant lab reports will not be accepted late and a zero grade will be assigned.
Lab Quizzes (15%)--About 10 or 15 minutes of most discussion meetings will be devoted to a quiz on the previous or next experiment. Questions will be in a multiple choice or free-response format and will be similar to pre-lab exercises and assigned questions; will include related chemistry from the lecture course; and will also evaluate your knowledge of the hazardous properties of the chemicals you worked with, and safety procedures. Quizzes cannot be made up. However, with a substantive and substantiable excuse you may be excused from a quiz, in which case the quiz will not be counted.
Technique (10%)--Your skill in the laboratory is assessed by the quality of results from investigative experiments and by the yield and purity of product from preparative experiments. There is no breakage charge for glassware; instead, that carelessness will be considered in this element of your grade.
Conduct (10%)--The teaching assistant will be aware of your attitude and behavior regarding safety, neatness, and preparedness.
Midterm exam (20%)--The midterm covers the first five experiments. Questions will be similar to quiz questions.
Final Exam (20%)--The final exam covers the last experiments. The nature of the questions is the same as for the midterm.
Campus Computer Network:
Information technology advantages of the campus computer network and the Internet at large are exploited as much as possible in the course. On the course newsgroup is posted discussions among students; popular issues in science and chemistry; and quiz and tests, answers and grades. You will become a subscriber to the course listserv in order to receive important announcements. You will find archived handouts, old quizzes, and pointers to other chemistry resources at the URL (uniform resource locator) for the course on the World Wide Web. And finally, many students find that the best way to communicate with the professor is by email.
If you do not already have a campus computer account you will find instructions for obtaining one on a handout in the laboratory. You will also find in the laboratory a handout providing basic instructions on using the mail software and reading newsgroups. After you have your account and are able to read and send mail you must subscribe to the course listserv. You can do this simply by sending an email message to majordomo@lists.umbc.edu that states "subscribe chem351L" in the body. All important announcements will issue on the listserv.
Be constantly mindful of safety.
