ADVANCED PLACEMENT CHEMISTRY SYLLABUS September 2014 - May 2015 Overview: Niagara Wheatfield offers one section of AP Chemistry, which meets five days a week for 42 minutes, with an extra period every other day for laboratory. This course is designed to provide a solid, first-year college chemistry experience, both conceptually and in the laboratory and should be challenging for every student. Students receiving a 3 or higher on the AP Exam may be eligible to receive college credit at some colleges and universities. The labs will serve as a supplement to the classroom instruction. Sixteen Laboratory hands-on laboratory experiments will be performed throughout the year accounting for for more than 25% of class time, and additional class time will be used to help students meet each of the learning goals in the AP Scientific Practices. Inquiry and Problem and solving skills, both on paper and in the lab, are emphasized throughout the course. Students will complete two to three labs a month during the first three quarters of the year. The final quarter will focus predominately on review, with students will taking several graded practice AP Exams in order to become familiar with the exam style help increase the students’ awareness of test-taking strategies. The course is organized around six “Big Ideas.” Each Big Idea is broken down into Enduring under standings and Essential Knowledge. Science Practices parallel these enduring understandings and Essential Questions. “ Big Ideas” Structure of Matter Properties of Matter Chemical Reactions Rates of Reactions Thermodynamics Equilibrium Science Practices: The science practices for AP Chemistry are designed to get the students to think and act like scientists. Students will be expected to learn to: Science Practice 1: use representations and models to communicate scientific phenomena and solve scientific problems. Science Practice 2: use mathematics appropriately. Science Practice 3: engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course. Science Practice 4: plan and implement data collection strategies in relation to a particular scientific question. Science Practice 5: perform data analysis and evaluation of evidence. Science Practice 6: work with scientific explanations and theories. Science Practice 7: connect and relate knowledge across various scales, concepts, and representations in and across domains. (*From College Board) It is highly recommended that students have successfully completed Regents chemistry and Algebra 1 before taking AP Chemistry, but is. Although all Regent’s topics are covered in detail in this course, they will be gone over quickly. More time is necessary to cover the increased complexity of the AP Curriculum. Suggested Math Skills for students entering AP Chemistry Knowledge of basic Algebra and Geometry Knowledge of how to measure and collect experimental data with respect to volume, size, mass, temperature, and pH Knowledge of how to determine the rates of chemical reactions Knowledge of how to calculate solute concentrations Knowledge of scientific notation Ability to apply basic concepts of probability and to conduct statistical analysis Knowledge of graphing, including how to set up axes and plot data *Note: Trigonometry and calculus are not mandatory Course Requirements: In this class, the Chemistry: The Central Science, Twelfth addition will be covered at a rate of approximately one chapter every 5 to 7 school days, with approximately 25 problems assigned and reviewed per chapter. The assignments are on a chapter or weekly basis. Chapter Exams consist of 20-30 multiple-choice questions and up to 4 free-response questions. A student’s grade is approximately a weighted average of the following: Tests Quizzes Labs Homework Materials: 45% 15% 25% 15% 3-ring notebook 3 subject notebook Graphing calculator (everyday) Test Prep book, (Princeton Review, 5 steps to a 5, Barron’s, etc.) Textbook: Brown, LeMay, Bursten, Murphy, and Woodward, Chemistry: The Central Science , Prentice Hall (2012),Twelfth addition.(provided) Course Outline: Readings and examples should be completed from the Chemistry Text for the corresponding chapter readings. These should be done before class meetings. Additional End-of chapter review questions may be assigned.
