3 Chemistry 100 Fall 2005 Dr. C. M. Lang SYLLABUS and COURSE POLICIES This course is a unique course in chemistry. First, it is designed primarily as a reading course! Secondly, it is designed for non-science majors; thirdly, the chemistry will be taught on a needto-know basis; and finally, the course looks at more than just chemistry it looks at the interplay between chemistry, your surroundings and life in general. Beginning last academic year, this course also satisfies the University requirement dealing with environmental literacy. Selected environmental issues will be explored from the perspective of data collection and evaluation. economics, business, law, the social sciences, psychology, education, the arts, or things gleaned from the public press. As your instructor, I can and will provide the chemistry. You will have to integrate its ramifications into your personal decision-making process. I probably have little expertise in your chosen academic field and perhaps you have little in mine. But, together we should experience a sort of synergism with all of us learning. Much of the context for our perspective on chemistry will be the environment a topic which has been and still is very much in the news. When all is said and done, hopefully you will have a better understanding of scientific principles and an appreciation for the academic discipline of chemistry. But, more importantly, I wish for you to be a wiser, more critically analytical citizen and a responsible steward of our precious natural resources. Written Assignments There will be three (3) written assignments for Chem 100. All submitted papers should include a cover page complete with title, name, section number and a brief abstract. The papers are to be typed or constructed using a word processing program. Use Times New Roman as a font (size 12), with margins of 1.5 inches on left and 1.0 inch on right, 1.0 inch header and footer, and be single spaced with double spacing between paragraphs. All papers are due on or before announced deadline dates. Late paper will be severely penalized. One paper is to be constructed from each of the following categories. Category A Consider This: or Sceptical Chymist: These are scenarios presented within the chapters of the textbook, Chemistry in Context 5 th Edition. A two to three page paper (excluding cover page) is to be constructed from one of the following scenarios: 1.12, 1.14, 1.25, , 2.21, , 3.8, 3.28, 3.38 The due date for Category A papers will be announced. (DUE DATE: ). You should note that some of the scenarios are written as if there is going to be a class discussion, debate, etc. on this topic. You are to ignore that impression and write a paper that focuses on the issue raised in the scenario. If, for example, the scenario refers to two positions on an issue, you should detail those two positions and remember, above all, to discuss the chemical principle(s) involved.

4 Written Assignments (continued) Category B Submit an article from a recent newspaper or legitimate news magazine which has an environmental theme and that makes at least one statement that you believe is misleading or erroneous. Remember to include full bibliographic information regarding the article. Use a highlighter or someway show the statement(s). Then, on an accompanying page or two, state why you think the statement is incorrect, false or misleading. Submit you position with explicit support from at least 3 referenced sources. A due date for this assignment will be announced. (DUE DATE: ) Category C Select a Risk/Benefit issue related to one of the topics below. Remember, risk has often been coupled to cost where cost is not necessarily financial. PCB s Food preservation by irradiation Artificial sweeteners Green Chemistry Stringent Character of FDA rulings Stringent Character of EPA rulings Nuclear power Radon in the Environment Organic vs. Inorganic gardening Food additives Health foods vs. regular foods Paper or Plastic packaging Nuclear energy as a home energy source Recycling Clearly spell out the risks and benefits of the issue selected and evaluate the risk/benefit ratio. Give support for your position. Cite sources in correct bibliographical form at the end of your paper. Number the sources sequentially and refer to them by number and page as a footnote reference. As an example, if page 11 of reference 4 is the source of a quotation, put (4:11) as a superscript following the quotation. I.e.,.. 4:11 The cover page of this assignment should contain information in the following form: Name, title of the assignment, date submitted and a 150 word maximum summary (abstract). The summary should include a statement of the problem or issue, reason(s) why the issue is important, risks identified, benefits identified, risk/benefit ration and your reflection on its significance. This is to be a 3 to 5 page paper, excluding references. The references should include at least 5 significant sources other than Chemistry in Context 5 th Edition. In general, this paper will have these parts: Abstract, issue, risk (perceived or real), benefits, and analysis of the risk-benefit ratio. Again, the due date will be announced. (DUE DATE ) Problem Assignments There will be no assigned problems to be graded. Rather, you are encouraged to work through the various exercises within the body of each chapter ( Your Turn, Consider This and Sceptical Chymist ) There are numerous Questions at the end of each chapter many of these questions are numerical problems which emphasize the material covered in lecture or in the text. As many of these items as possible ought be worked out so as to enhance your understanding of the principles being taught. They will not be collected but you should keep an organized notebook of such items. Solutions to these items can often be found on the web at McGraw-Hill s Chemistry-in-Context website located at

5 - 3 - Laboratory Experiments The experiments are an integral part of this course and you will note that many are scheduled. Often students find that laboratory experiments give concrete insights into understanding chemical concepts. Thus, experiments help to clarify and extend the thinking process. It is my hope that you find them interesting, challenging and even fun. You are expected to be prepared to do the experiment(s) on the scheduled date. This means you will have to carefully study the relevant material in the text and laboratory manual prior to conducting the experiments. The experiments will be taken from a laboratory manual that is currently under construction. Titled Chemistry for the Citizen: A Laboratory Manual, the various experiments will be made available to you electronically either as attachments to an message or as a pic from my homepage ( Report forms are an integral part in the construction of this manual. Since the laboratory exercises will be conducted by teams of students, only one report will be turned by each team. The report will include all materials instructions, data, discussions and answers to questions. Reports shall be turned-in at the close of the laboratory session. Evaluation of your laboratory reports will emphasize evidence of prior planning; i.e., it is hoped that nothing has to be rewritten. Bring your textbook and laboratory manual with you to every class period as we will likely have many opportunities to use each. Bring a calculator also as it could save you hours of work. Finally, all students must follow the safety rules as established by the UW-SP Chemistry Department. Read over the section on safety on page vii of the laboratory manual and all hand-outs provided in Laboratory C-128. Generally, contact lenses should not be worn in a chemistry laboratory. At all times, students must wear goggles and a protective garment (such as a lab apron, lab frock, lab coat, etc.) when present in the laboratory. Remember the safety rules are designed to protect you from your neighbor as well as from yourself! (Think about that for a moment.) Examinations and Quizzes There will be two (2) hour examinations and a cumulative final examination. The dates for the examinations are as follows: 1 st Hour Examination 13 October 2005 (R) covering material from Chapters 1, 2, 3. 2 nd Hour Examination 22 November 2005 (T) covering material from Chapters 4, 5, 6. Final Examination (2 hours) 17 December 2005 (Sat) from 14:45 to 16:45 pm comprehensive but with an emphasis on material from Chapters 7-9. These times are fixed. No provisions have been made for make-ups Attendance and Class Participation It is expected that you will be present at all class sessions (lectures and laboratory sessions) for which you are enrolled. In general, it is not possible to make-up missing a class. See me about making special arrangements if a laboratory session is unavoidably missed.

6 Attendance and Class Participation (continued) Remember, the Your Turn, Consider This and Sceptical Chymist sections of your textbook give you an opportunity to apply chemistry to everyday life or, perhaps offer a view of things from a different perspective. It is in these cases where your background, prior experiences and initiative can really shine. Come to class prepared for taking an active role in our consideration of the issues in these sections. Grading Two (2) hour 100 points each 200 points Final 200 points Three (3) writing 100 points each 300 Thirteen (13) lab 25 points each. 325 The grading scale will be no more stringent than % A 80-90% B 70 80% C 60 70% D less than 60% F Total points
