V. METHODS OF INSTRUCTION/COURSE ORGANIZATION: To be determined by the respective instructor. VI. ATTENDANCE PROCEDURE (INCLUDING MAKEUP POLICY): To be determined by the respective instructor. VII. BIBLIOGRAPHY OF READINGS (IF APPLICABLE): To be determined by the respective instructor, but must include a literature project of the students choice that meets the following criteria. A six to ten page term paper on any current research being done in CHEMISTRY that interests the student is to be organized and written over the semester. The paper must have at least 5 juried references, 2 may be from the Internet. The other three sources must be from a current book and/or scientific journal. All sources must be properly referenced by APA, MLA, or ACS and depending on choice, must be consistent throughout the paper. The paper should answer a question concerning a specific “current” research topic in chemistry. The paper is developed by answering a specific question. It should be focused on a “narrow” topic rather than staying too broad. Some topics of interest are but not limited to chemical/industrial processes, forensic chemistry, atmospheric chemistry, nutrition, health, medicine, genetics, environmental issues, nanotechnology or other chemical technology. Bibliographic instruction should be presented to the students during the first 2 weeks of the semester. The topic of the term paper should be approved by the instructor about 2 weeks into revised 3/12 the semester, an outline should be submitted before mid-semester and the final paper due before finals week. The paper should be structured in the following way and appear so in the outline. 1. Introduction – This should contain a discussion of the question or problem that is to be presented in the paper. ex. What is being done on "state-of-the-art control technology" used to sequester CO2 in coal-fired electrical power generation? 2. General Background – This section should include a discussion of the chemicals pertinent to the topic. Chemical structure, molecular weight, physical and chemical properties, general reactivity, and reaction mechanisms are all part of this section. 3. Current Research & Theoretical Perspectives– The student will discuss the current research being done on this topic as well as theories that are used to explain the research topic as presented by the researcher. (This is the bulk of the paper.) 4. Opinion – This section includes the student’s perspective on the "science" of this topic and should emphasis agreement or disagreement with the information, research, and approach with respect to the current research and theoretical perspectives. A discussion on ethics relative to this topic could also take place in this portion of the paper if applicable. 5. Conclusion – The student will wrap the paper up into a final discussion or summary that serves as an overview of the question or statement made in the introduction. 6. Bibliography - must be complete and follow the style writing chosen to use in the paper. VIII. METHODS OF EVALUATION (INCLUDING THE CALCULATION OF COURSE GRADE): To be determined by the respective instructor. The methods of evaluation shall include tests (test types, length and weight of each), papers (weight of each), projects (weight of each), and other forms of evaluation (weight of each). IX. GRADING SCALE: To be determined by the respective instructor. The grading scale shall indicate what numerical scores correspond to the following grades: A, A-, B+, B, B-, C+, C, C-, D+, D, and F. Please Include: If you have, or suspect you may have, any type of disability or learning problem that may require extra assistance or special accommodations, please speak to me privately after class or during my office hours as soon as possible so I can help you obtain any assistance you may need to successfully complete this course. You should also contact Laurie Bethka, Room 420M in the Academic Assistance Center, for further assistance. X. GENERAL TOPICS OUTLINE: 1. Gases & Their Properties 2. Intermolecular Forces & Liquids 3. Chemistry of Solids 4. Solutions & Their Behavior 5. Chemical Kinetics 6. Chemical Equilibrium 7. Acids & Bases & Other Aspects of Aqueous Equilibria 8. Entropy & Free Energy 9. Electrochemistry 10. Nuclear Chemistry revised 3/12 XI. ACADEMIC INTEGRITY: Academic honesty is expected of all Clinton Community College students. It is academically dishonest, for example, to misrepresent another person’s work as one’s own, to take credit for someone else’s work or ideas, to accept help on a test, to obtain advanced information on confidential test materials, or to intentionally harm another student’s chances for academic success. XII. COURSE CONTINUITY PLAN: In the case that the college officially closes because of an emergency which causes a short term disruption of this course, we will utilize e-mail to continue this course in the short term (1-3 weeks). All students need to utilize their campus email to receive course related information. XIII. TECHNOLOGY STATEMENT: A CCC student should expect that any class may require some course activity that uses a computer and the internet. Activities could include but are not limited to accessing the course syllabus, schedule, or other handouts on a website, completing homework online, taking quizzes or submitting written work, participating in a discussion or sending/receiving email. revised 3/12
