2 TEXTBOOK: Zumdahl, Steven and Susan Zumdahl. Chemistry, Ninth Edition. (publisher Brooks/Cole Cengage) 9th Edition AP Edition 04 [CR] STRUCTURE OF THE COURSE: [CR] AP Chemistry is built around six big ideas and seven science practices. The big ideas are: Big Idea : The chemical elements are fundamental building materials of matter, and all matter can be understood in terms of arrangements of atoms. These atoms retain their identity in chemical reactions. Big Idea : Chemical and physical properties of materials can be explained by the structure and the arrangement of atoms, ions, or molecules and the forces between them. CR Students and teachers use a recently published (within the last 0 years) college-level chemistry textbook. CR The course is structured around the enduring understandings within the big ideas as described in the AP Chemistry Curriculum Framework. Big Idea : Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons. Big Idea 4: Rates of chemical reactions are determined by details of the molecular collisions. Big Idea : The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter. Big Idea : Any bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations. The science practices for AP Chemistry are designed to get the students to think and act like scientists. The science practices are: Science Practice : The student can use representations and models to communicate effectively concerning scientific phenomena and solve scientific problems. Science Practice : The student can use mathematics appropriately. Science Practice : The student can engage in scientific questioning to extend thinking or to guide investigations within the context of the AP course. Science Practice 4: The student can plan and implement data collection strategies in relation to a particular scientific question. Science Practice : The student can perform data analysis and evaluation of evidence. Science Practice : The student can work with scientific explanations and theories. Science Practice 7: The student is able to connect and relate knowledge across various scales, concepts, and representations within and across domains.

3 LABORATORY INVESTIGATIONS: The laboratory portion of this class is designed to be the equivalent of a college laboratory experience. Because some colleges require proof of the laboratory portion of the course before granting credit, all students will keep a laboratory notebook, provided by the teacher. At a minimum, twenty-five percent of instructional time will be spent in the laboratory. [CRa] When the students finish AP Chemistry, they are encouraged to take their laboratory notebook with them to college. It includes seventeen laboratory investigations. They are all primarily wet labs, (one virtual). Six of the labs are guided inquiry based. Each report in the student s laboratory notebook has sections on purpose, procedure, equipment needed, data, analysis, questions for the students to answer, and conclusion. [CR7] Students must turn in completed laboratory reports for each lab. Each student is required to communicate his or her results once per semester using a method of his or her choice (PowerPoint, Poster, Classroom web page, etc.) Laboratory Equipment The school is equipped with a full range of glassware (beakers, flasks, burets, eudiometer tubes, pipets, etc.), instruments (Spec-0s, analytical balances, centrifuges, ovens, etc.), and data gathering probes. All of the students have access to a computer with a full range of MS Office products on them. In addition, all computers have Vernier, Pasco and Graphical Analysis software on them, so students can use those programs to analyze laboratory data. Data can be collected; () by the students, () via computer, or () via data gathering handheld units. All data is recorded in their laboratory notebook. Laboratory Investigation Sequence First Nine Weeks MSDS and laboratory safety Students read and understand MSDS.

CR7 The course provides opportunities for students to develop, record, and maintain evidence of their verbal, written, and graphic communication skills through laboratory reports, summaries of literature or scientific investigations, and oral, written, and graphic presentations. CRb Students are provided the opportunity to engage in a minimum of hands-on laboratory experiments integrated while using basic laboratory equipment to support the learning objectives listed within the AP Chemistry CR The laboratory investigations used allow students to apply the seven science practices defined in the AP Chemistry At minimum, six of the required labs are conducted in a guidedinquiry format.
