AP Chemistry Warren East High School 2012-2013 Jennifer Cooper jennifer.cooper@warren.kyschools.us website: www.teacherweb.com/KY/WarrenEastHighSchool/JenniferCooper/ General Course Information The AP Chemistry course will have many overall goals, however the three primary goals are: 1) to provide college-level chemistry instruction 2) to provide college-level laboratory experience 3) to prepare students for the AP Exam in such a way that they will have the best chance for success. ● In AP Chemistry, students will learn more in-depth chemistry than they did in their first-year course and build upon their understanding of chemical concepts to prepare for the AP exam. The course work is rigorous and fast paced since it is designed to take the place of two semesters of freshman inorganic chemistry. Therefore, it is expected that AP Chemistry students complete a minimum 1 to 1 ½ hours of homework each night. Learning from the textbook and doing the homework are the students' responsibility. The course meets all of the standards designated by the College Board and covers all of the topics in the AP Chemistry Course Description. Course Objectives The objectives of the AP Chemistry course are that each student will: exhibit mastery of the major principles of chemistry with a focus on the major themes from the Course description (structure of matter, states of matter, reactions, descriptive chemistry, and laboratory). demonstrate laboratory skills by using various types of chemical instrumentation, technology, and scientific methodologies. solve scientific problems by making observations and collecting data. Textbook and Materials Primary Textbook: Chemistry The Central Science, 10th edition by Brown & Lemay Supplemental Textbooks: General Chemistry, 5th edition by R. Chang and Chemistry, 6th edition by Zumdahl & Zumdahl. Students will need the following materials in order to be successful in the course: A 3-ring binder (minimum 3” rings) that is used only for the AP Chemistry course & tab dividers Composition lab book Graphing Calculator A computer with internet access lined and graph paper Teaching Strategies Students will be engaged in many instructional activities during each unit, which will utilize guided inquiry and student-centered learning. All lectures will contain PDF notes and will be supported by the textbook. It is the students' responsibility to read the chapters and work the problems. The PDF notes can be accessed from www.apchemistrynmsi.wikispaces.com. The website also provides video lectures that correspond to the notes. ●Required AP Chemistry Laboratory Program. Students will compile a laboratory notebook that will include an abstract, the lab write-up, answers to lab questions and all data and observations. ●Unit exams will mirror the AP Exam. Exams will feature multiple choice questions and freeresponse questions. They will be graded and scored with AP grading policies and rubrics. Summer Assignment Every AP Chemistry student should have an in-depth knowledge of the following concepts prior to the first day of school. These concepts will only be reviewed during the first days of class, and are the fundamental components to understanding higher level chemistry. A detailed Summer Assignment with instructions and notes is available on my webpage. The assignment should be completed by the first day of school to prepare for the first exam. Fundamental Chemistry Concepts: Chemical Reactions: AP Chemistry students should have an understanding of the different types of chemical reactions, balancing equations, prediction of products, mass relationships and some stoichiometry. Nomenclature: A fundamental component to chemistry, each student is expected to write chemical formulas, calculate empirical and molecular formulas, and write chemical equations. There is not enough time to re-teach this information, and it is vital that students review and master the content before the end of the first week of school. Atomic Structure and States of Matter: AP Chemistry students should understand the fundamental concepts of atomic structure and how atoms form ionic and molecular bonds. Students should also have an understanding of the kinetic molecular theory and how it relates to the states of matter. Laboratory Component The difference between college chemistry and the typical high school chemistry course are evident in the laboratory work. The AP Chemistry Exam includes some questions based on experiences and skills students acquire in the laboratory. Students will complete approximately 22 of the suggested AP Chemistry Labs in the AP Chemistry Lab Manual for Students. There will a minimum of one day per week where students will be required to arrive to class early or stay after class to set up or finish a lab. Formal lab reports must be maintained in a composition notebook and follow a specific laboratory format. Laboratory Dress Code: During laboratories, it is important to wear clothing that will not interfere with the experiments. Students who come to lab inappropriately dressed or otherwise unprepared will NOT be allowed to participate in the scheduled lab experiment and will receive a grade of zero (0) for that lab assignment. Remember that lab safety requires each student to prepare for lab prior to arrival in order to be organized and efficient during the laboratory period. Protective eyewear (goggles) will be provided in the lab and must be worn at all times, unless I state otherwise. Grading Policy Weight Activity Points Tests 100 Quizzes At most 50 Labs Variable Notebook 20 Homework Variable 70% 25% 5% Description Consist of a multiple choice and a written part, each worth half the test grade. Most questions will be AP style questions, and the test itself will model the AP test. Consist of multiple choice and/or written questions. Quzzes will not necessarily model the AP test, but may consist of AP style questions. Weekly Net Ionic Quizzes will model the AP exam and will be graded using AP standards. Each lab experience will require a pre-lab assignment and a formal write-up that includes a statement of the problem, hypothesis, description of the experimental procedure, organized experimental data, analysis of experimental data, and a conclusion that relates to the hypothesis and problem including error analysis. Labs will be completed in a lab notebook. Instructions for completing the lab notebook will be given in class. A notebook will be required and checked at the end of each unit. Notebooks are required to have notes, page organizers, handouts, and completed example problems. Homework will be assigned most nights and will consist of problems from the text, supplemental materials from any of the texts and/or work sheets.

Assignments must be turned in even if you are absent from class. Late assignments will be docked 10% every day that it is late and will not be accepted after the fifth day. Since many of the labs deal with chemicals that need proper storage; it is important that labs are not missed. If you have an excused absence on the day of a lab, you must make arrangements to stay after school the day you return to complete the experiment. Make-Up Exams If you are absent from class and it is excused, you will be given the opportunity to make up any missed work. However, it is your responsibility to obtain missing assignments and the date I expect you to turn it in. There will be no make up work for any other reason. Work not made up will receive a 0. Remember if your absence is unexcused you will receive a 0 for any work turned in that day. If you miss a test, quiz or lab due to an excused absence or field trip, you will need to make it up before school, after school, or an arranged time or you will receive a 0. Typically labs and exams must be made up within one school week of an absence due to the fast pace of the course. You will not make up TESTS or LABS in class. Your grade will reflect a 0 in the computer until that grade is made up. If you know ahead of time that you must miss an exam, please schedule the make-up exam in advance. If you are ill on an exam day, you must schedule the make-up exam the day that you return. In general, you will be given a one-day extension for each day that you were absent. Study Hints Go over your class notes each night and be honest with yourself in judging whether you understand what was covered in class. Use the textbook for clarification and enrichment, and come to the teacher for help when needed. If you are having trouble with a concept or problem, it is helpful to write questions down in your notes so that you are prepared to ask questions in class. Although homework is only worth 5% of your grade, it is the best preparation for the exams. If you chose not to complete homework, you will have difficulty on the exams. Form study groups and work as many practice problems in the textbook as needed. Students learn best when they explain content to a peer. Work carefully and consistently on lab reports. The experiments are designed to support content in the course. There are specific lab questions on the AP Exam. Pay attention to lab safety and techniques, common ion colors and reactivity, and mathematical formulas used in labs. Use the livescribe videos and notes when you study at home. The videos go through the notes in detail and describe how to work the problems. It is more beneficial to read the notes and chapters prior to lecture. Again, students that do chemistry homework will do better on a chemistry exam!
