1 AP Chemistry Syllabus Classroom number: S202 Instructor: Mr. Krouba Website: LSHS Telephone #: (770) Course description: The AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first year of college. For some students, this course enables them to undertake, in their first year, second-year work in the chemistry sequence at their institution or to register in courses in other fields where general chemistry is a prerequisite. This course will be centered on the six big ideas provided by the College Board. A special emphasis will be placed on the seven science practices, which capture important aspects of the work that scientists engage in, with learning that combine content with inquiry and reasoning skills for more than 25% of the class time. This course is open to all students who have successfully completed a first year chemistry course. The objectives achieved while teaching this course are focused around the framework the College Board has provided from the six big ideas. Big idea 1: Structure of matter (BI1) Big idea 2: Properties of matter-characteristics, states and forces of attraction (BI2) Big idea 3: Chemical reactions (BI3) Big idea 4: Rates of chemical reactions (BI4) Big idea 5: Thermodynamics (BI5) Big idea 6: Equilibrium (BI6) Academic integrity LSHS students are expected to conduct themselves in accordance with five fundamental values: honesty, trust, fairness, respect, and responsibility. Students are to act so that they are worthy of the trust bestowed on them by the teachers and peers, conduct themselves honestly, and carry out their responsibilities with honor and fairness. Plagiarism is defined as copying work that is not your own and taking credits for its creation. It includes downloading research papers from the internet, buying papers from a commercial source, copying articles from the web or other databases, copying work from other students, cutting and pasting together text from several sources, faking citations, or quoting less than all the word copied to change the tone or style of the source. Cheating occurs when students copy homework, papers, or exam answers from other students and

2 submit the work as their own. Both plagiarism and cheating will result in zero credit for the work for all students involved in the unauthorized activity and may also result in disciplinary action. In many cases collaboration is to be encouraged, depending on the nature of the assignment. Collaborative learning is, in general, highly consistent with LSHS beliefs. Inappropriate collaboration is working with others in ways contrary to the teachers instructions. If your teacher has instructed you not to collaborate and you do so, it is cheating. Unless otherwise instructed by your teacher, the conclusions you draw and the paper you write are to be a product of your own creativity, thinking, and work. Textbook: Zumdahl, Steven and Susan Zumdahl. Chemistry, 7 th Edition. Boston, New York, Houghton Mifflin Company, 2007 Required Materials: Carbon capable laboratory notebook, TI-83 calculator Laboratory Work All of the laboratory experiments in this course are hands-on. Students work individually or in a group of two depending upon the lab. They collect, process, manipulate, and graph data from both qualitative and quantitative observation. Inquiry is emphasized in many of the experiments that students complete. The laboratory work requires students to design, carry out, and analyze data using guided inquiry principles. Data is often shared to allow for statistical analysis. Each student, for all labs, will answer questions in writing and prepared analysis, conclude for each laboratory assignment, and connect the results with the objectives of the laboratory. The mastery of the laboratory objectives is assessed via lab reports, lab quizzes, and hands-on semester laboratory exams. All laboratory experiments are intended for a full block period except the guided-inquiry labs that require a double block periods. 1. Determination of the Formula of a Compound 2. Finding the Ratio of Moles Reactants in a Chemical Reaction 3. Progressive Precipitation 4. Hess s Law 5. Relationship Between the Spectrum and Absorbance of Light 6. Conductivity of Solids and Metals 7. Factors that affect reaction rates and determining reaction rates and reaction mechanisms 8. Equilibrium Position 9. Hydrolysis of Salts 10. Electrochemical Cells Laboratory Notebook A laboratory notebook is required for the course. All completed lab reports documenting all lab experiences must be included in the notebook. The notebook is checked every nine weeks with a final check at the end of the course. Tests A chapter test is assigned for each chapter. A comprehensive, standardized semester exam is administered at the end of 1 st semester and a final exam at the end of the year.

3 Grading policy Douglas County Grading Scale ( A; B; C; 70 D; below 70 F) All grades can be categorized into two groups, summative and formative. All grades should ne academic and relevant to the course. Extra credit work should be academic. Summative assessments: 50% -Exams Formative grades: EOCT/ Final exams: - Labs - Projects - Midterm and other similar assignments 30% - Quizzes - Classwork - Homework 20% -Final exam Minimum Numbers of grades: (18) grades per (9) weeks. Every two weeks will be updated in the Student Information System. Course Outline: Chapters in Zumdahl AP chemistry Topic covered 1. Chemical Foundation None 2.
