• Class meets four times each week: two times for 57 minutes each and two times for 87 minutes each (288 minutes total) • Prerequisites: successful completion of one year of general chemistry and two years of algebra • Textbooks: Each student will be issued a copy of Brown, LeMay & Bursten: Chemistry, The Central Science (8th Ed.). In addition, I have a set of Chang: Chemistry (6th Ed.) that may be either issued to students or used in the classroom, depending upon student enrollment numbers. Each unit in the syllabus refers to assigned readings by first author initials: B = Brown, LeMay and Bursten, C = Chang. AP Chemistry is a second year chemistry elective. It is designed to approximate the instruction and laboratory experience that students receive in a freshman-level college general chemistry class. Consequently it bears stating that the course is rigorous and relentless. The prerequisites listed above are minimum requirements. It is impossible to underestimate the value of strong math and written and verbal communication skills. Students will be deriving and making use of mathematical equations throughout the year; there will be extensive writing and oral presentations. Because successful completion of first year general chemistry is a requirement of all Advanced Placement Chemistry students, I am aware of the foundational information they bring with them to this second year of instruction. Each student will complete a summer assignment intended to "remind" them of the basic tools that underlie so much of what is to come. We will spend about a week (much of it in the lab) clarifying any questions and then move on to more advanced topics. The class is taught in reverse order from the first year: This gives us a full semester, in the fall when the students are fresh and less distracted, to cover the new, more intensive topics: kinetics, equilibrium, thermodynamics and electrochemistry. Over the years, I have found that this works very nicely as we can review the fundamentals while we are taking our time with these more difficult topics. The third quarter is spent revisiting the elements of first year chemistry in greater depth, always integating this information with the topics of the first semester. The final quarter is spent reviewing for the AP exam. "Reviewing" encompasses a myriad of methods, including more labs, reading scientific literature, games, past AP exams, examining AP review books. I do not spend a great deal of time lecturing about each topic. Students are given reading assignments and applicable problems to solve. They are expected to outline the readings, make note of questions they need to have clarified and work the problems. We make frequent use of a remote classroom survey system (I-Click is the unit we own) for "reading quizzes" and peer instruction. Students are assigned poster presentations for each unit (this is done on a rotating basis and by the end of the school year, all students have done their share). For each unit, students will complete and turn in homework problems, both of an on-line ("LonCapa") and paper & pencil ("problem sets") variety. Assessments take different shapes: I expect students to have strong written and verbal skills as well as strong math skills. I make every effort to select lab activities that reinforce the topic we are studying in class at the time of the lab. Laboratory: class is always positioned either first thing in the morning or right before lunch in order to accommodate extended time needed for labs. Many labs are completed over successive class periods. All labs are accompanied by a formal report that generally includes the title, objectives, materials used and methods employed, data table, calculations and conclusion, including an error analysis. I consider the error analysis to be a critical part of the conclusion and I set a format for this analysis: state the error, tell which measurement is affected by this error, indicate where in the calculations this measurement appears and then indicate whether the error made the result erroneously high or low. While students work together for most labs (qualitative analysis is the exception -- each student has a different unknown), each is required to turn in an individual report of their work. Students will maintain a lab folder containing the final drafts of their lab reports and a stitched composition book containing the rough drafts, lab notes, calculations, etc. Unit 1: Review of Basics (covered over summer + 1 week in fall) Content: (B: ch. 1/3, C: 1/2/3) Metric Measurements Significant Digits, Dimensional Analysis Naming, Formulas, Balancing, Mole Ratio, Stoichiometry Solubility Rules Assessments: Lon-Capa Problem Set Labs: 1.
