AP CHEMISTRY SYLLABUS Erich Schneider Text: Brown, Theodore E., H. Eugene LeMay, and Bruce E. Bursten. Chemistry: The Central Science. 10th Edition. Upper Saddle River, NJ: Prentice Hall. Assessment: We will cover four units during each academic quarter. Each unit will include: Daily homework assignments consisting of a selected reading and questions from the text. Occasionally, worksheets will be assigned. Assignments can be found on my web page. 1-2 labs with write-ups. See below for more detail. A review packet the will help prepare you for the test. These will include notes, straightforward questions as well as pertinent multi-step questions from past AP exams. In class, we will work together to learn the new material and go over problems. Due to the small class size in AP Chemistry, students should expect and be prepared to participate daily in our class discussions and to learn from each other as much as possible. A test on each unit. Tests will account for 70% of each quarter grade. (Lab reports: 15%; Homework/Participation: 15%). Once corrected, we will go over each test thoroughly allowing you to make corrections. You will be permitted to keep your tests for review. More on The Lab Component: Labs are an integral part of the AP curriculum. Every unit will include one or two hands-on labs. Students will work in pairs to collect data and observations in their notebooks and may collaborate when assessing their data and planning their calculations. Each lab group will have the opportunity to discuss the results of the lab informally in class. However, students must work independently when preparing their lab reports and answering follow-up questions. Lab write-ups will typically include a purpose, a neat and organized presentation of data and calculations, a conclusion and frequently, answers to follow-up questions. Given the expectations of the AP curriculum and the constraints of our daily schedule, students may be required to give up a portion of their lunch break and/or meet after school to complete some of the lab work. The Importance of your First Year in Chemistry: The knowledge and lab skills you acquired in your Honors Chemistry course will prove to be essential to your success in AP Chemistry. In essence, this course is the second part of a two-year Chemistry curriculum. As you may recall, there were many times throughout your Honors Chemistry curriculum when we went above and beyond the textbook to cover a topic. Some of these topics included quantum numbers, the HendersonHasselbalch equation, the hydrolysis of salts as well as the memorization of a long list of polyatomic ions. You completed many hands-on labs that allowed you to develop numerous laboratory skills. Some of these labs were actually AP level labs. You will come to appreciate the extensive knowledge and skills you mastered during your first year of chemistry. Labs Completed During the First Year of Chemistry 1.
