AP® Physics B - Syllabus Text: Serway, Raymond A., and Jerry S. Faughn. 2006. College Physics, 7th ed. Belmont, Calif.: Brooks/Cole Publishing. ISBN: 0-534-99724-4 About the AP Physics B Course: Schedule is based on a rotating class schedule: Class meets 4 days week for 54 minutes for lecture, with a double period once a week for labs. The course will follow the Advanced Placement Physics B Curriculum published by the College Board. The units of study for this course coincide strongly with the AP Physics B materials developed by the National Math and Science Initiative. Additionally, the units for this course were developed using the AP Physics Objectives and Syllabus Indicators provided by the College Board to ensure an in depth course of instruction. Students are encouraged at the beginning of the school year to create or join a study group in which to work while in class and outside of class. Cooperative learning and peer assessment are essential parts of the course. Course objectives include developing the student’s critical thinking skills, and investigative skills to read, understand, and interpret physical information. The student must use the scientific method to analyze a particular physical problem and use basic mathematical reasoning in a physical situation or problem. The student must perform experiments, interpret the results, and communicate those results that include error analysis and uncertainty. Grading Policy: • Tests: 50 percent Tests are administered after each unit of material. Each test consists of three sections: 1. Multiple-choice questions 2. Free-response problems 3. Lab-based question: may include questions on labs done in class or questions on a lab that was not performed in class. • Labs: 25 percent Labs: All labs are “hands-on” activities. The time allotted for lab is for conducting the experiment and recording the data. The students perform the analysis and complete the report outside of class. Students are required to keep a portfolio containing all their lab reports in case the college of their choice requires evidence, or documentation prior to awarding college credit for physics. (additional information in the lab section below) • Quizzes –20-25percent Quizzes: Quizzes may contain questions and/or problems from the homework, the reading assignments, and/or recently covered or previously learned material. • Homework and In-class Problems –1to 5 percent Homework assignments are given from the textbook and from AP Released Exams. Sometimes students will be graded on in-class problem-solving exercises, AP Released Exams. Most homework will not be graded but the student should expect in-class quiz over the homework. After each semester there is final exam that is 20% of your final grade. Each quarter grade is 40% of your total grade. Ipad,pc, tablet and Wireless Classroom rules o You may bring in your ipad, pc, or tablet to take notes or to refer to class documents. o You may bring in your ipad,pc, or tablet to turn in a lab report or take pictures for labs. o Refer to Student handbook for rules and guidelines. o The teacher at any point can ask for no use of electronic devices in the classroom.

All labs are hands on and in some labs, Vernier® Sensors with TI Calculator or LogPro3 software will be used to collect data and preform analysis. Students are given an objective, e.g. “Determine the coefficient of static friction of wood on wood”, and standard materials – string, ruler, protractor, mass set, light pulley, CBL, etc. In some cases, students are allowed to create their own experimental design, but ultimately the lab designs will lead to the collection of data which can be analyzed through graphical methods. Students must graph by hand using a ruler and graph paper, but are encouraged to check their work with a spread sheet or statistical functions on their graphing calculators. Students work in pairs, but each student must submit a lab report which is turned in the day after the conclusion of each activity, then graded and returned. Each Lab report will follow the below format • a statement of the problem • an hypothesis • a discussion or outline of how the procedure will be carried out, • the data recorded • a discussion or outline of how the data was analyzed • a conclusion including error analysis and topics for further study Below you will find the list of labs: 1.
