Advanced Chemistry (AP Chemistry) Syllabus Course description: Advanced Chemistry (AP Chemistry) is a college-level chemistry course equivalent to a freshman level chemistry course in college. The course covers five broad themes of chemistry: the structure of matter, states of matter, reactions, descriptive chemistry, and laboratory methods. Students are prepared to be critical and independent thinkers who are able to function effectively in a scientific and technological society. Students will be able to analyze scientific and societal issues using scientific problem solving. Students will be prepared to make an acceptable score on the AP Chemistry Examination in May. Time Commitment (Curricular Requirement 7): Advanced Chemistry (AP Chemistry) meets 5 times a week for 51 minutes each day. An average of 102 minutes (2 class periods) per week will be spent on laboratory experiences. Consequently, students will need to spend 6-9 hours per week outside of class reading the textbook, problem solving, collaborating with other students, and reporting lab results. Laboratory Component (Curricular Requirements 5 and 7): Students will perform laboratory exercises equivalent to a college-level chemistry course. In each laboratory experiment, students will physically manipulate equipment and materials in order to make relevant observations and collect data. Students also will use the collected data to form conclusions and verify hypotheses. Students are expected to communicate and compare experimental results both informally and formally. Students will be required to keep a formal lab notebook in which background information, hypotheses, procedures, collected data, observations, graphs, calculations, and conclusions can be reported for each experiment. Students will also be expected to present their laboratory results informally and formally through presentations made to the class. Problem Solving (Curricular Requirement 6): Students will be required to solve problems involving many different chemical calculations throughout the course. Textbook problems as well as released items from old AP examinations will provide students the opportunities necessary to engage in chemistry problem solving. Students will be required to present to the class their solutions to the AP released exam questions. A minimum of 2 presentations will be required each quarter. The goal of the presentations is to improve each student’s ability to communicate scientific results.
