Big Idea 3: Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons

Transcription

1 Advanced Placement Chemistry Course Syllabus General Course Description: This course will cover a curriculum that aligns with the framework specified by the College Board. This framework, as published in the 2013 version of the AP Chemistry Course and Exam Description, outlines six big ideas. All course topics, activities, assignments, and laboratory investigations will align with these six big ideas. Big Idea 1: 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 2: 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 Big Idea 3: 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 5: The laws of thermodynamics describe the essential role of energy and explain and predict the direction of changes in matter Big Idea 6: 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 A college-level chemistry textbook will serve as the basic reference for this course. Topics will be covered using the textbook and teaching methods that cover material in a spiral approach. Students will be required to review class material nightly. Homework problems and questions will be assigned daily. Laboratory work is performed regularly, and will comprise a minimum of 25 percent of instructional time. Laboratory investigations will be conducted collaboratively, require a comprehensive laboratory notebook to journal observations and collect data as well as individual written laboratory reports. All laboratory work must be preformed within the safety guidelines set forth by the Flinn Scientific and Rose Tree Media School District safety contracts. This course is intended for the serious student who desires a strong foundation in chemistry. Since this course meets six periods per week, there may be a schedule conflict with the remainder of the student s schedule. Therefore, students selecting this course should identify an alternative elective to provide more flexibility in scheduling.

2 Students who select this course should count on studying the above topics at a level, which is comparable in content and difficulty to a first-year general chemistry course at the university level. Students taking this course will be encouraged to take the College Board Advanced Placement Exam. Prerequisites: 1 Chemistry (recommended) or a B or better in Chemistry.

Laboratory Component: As previously stated, laboratory work is performed regularly, and will comprise a minimum of 25 percent of instructional time. The purpose of the laboratory component is to provide students with the opportunity to engage in investigative chemistry. These labs include both instruction-based experiments and inquiry-based experiments. The following experiments will be preformed over the course of the year: Experiment 1: Basic Laboratory Techniques Experiment 2: Alum from Waste Aluminum Cans Experiment 3: Verification of Potassium Aluminum Sulfate in Synthesized Alum Experiment 4: What Makes Water Hard?

Each experiment will begin with a title page where the title, purpose, and pre-lab questions are completed. While it is not necessary to re-write the pre-lab questions, the answers provided must be in complete sentences with the question stated in the answer. All data entered in the lab notebook must have numbers with descriptive units in correct significant figures. All calculations must be supported with work. In the case where a single calculation is repeated, the work of one sample calculation will suffice. If a graph of data is required, it is to be included in your lab notebook. All graphs require titles and labels. Each experiment will include an explanation of data and results, including the identification and explanation of relevant experimental errors. Finally, each experiment will include a written conclusion. The conclusion of the experiment should relate directly to the purpose of the experiment. All pages in the notebook are to be numbered. The notebook is to include a table of contents, which lists the title of the experiment and the page number where it can be found. This table of contents must be updated regularly.
