AP Physics B Syllabus SY: 2013-2014 Course Overview Advance Placement Physics B is an algebra-based physics course equivalent to university level general physics course. It is offered to high school students who have taken Pre-AP Physics, Algebra, and Geometry in the previous years. Students in this course are required to concurrently take Pre-Calculus in order to increase their mathematical ability in problem solving. This course will cover two semesters. The students are expected to understand the concepts of physics, use scientific problem solving, and conduct laboratory investigations in safe, environmentally appropriate, and ethical practices.

Laboratory activities in this course are scheduled after school once a week, allowing for two hours to complete the labs. Each of the following laboratory investigations will be presented to the students in the form of a problem. Based on a demonstration of a physical phenomenon, students are lead in a guided discussion to formulate a hypothesis and test it. Provided with equipment and materials, they will be required to design and carry out an experiment to test their hypothesis. They shall make observations, gather data, analyze data and form conclusions and write it down in their journal as they perform the investigation. Formal typewritten lab report will then be turned in the following week. Students will be required to keep all typewritten reports in an organized portfolio. The following is a list of hands-on laboratory activities, some of which will utilize TI84/CBL programs. 1. Height Versus Time (open-ended lab) Given a meter stick, stopwatch and a basketball, students are to design an experiment to show the relationship between height and time of a bouncing ball. Students should be able to follow and write a laboratory report using scientific method with emphasis on dependent, independent and control variables. 2. Graph Matching Using CBR/CBL/TI-84, the students will create, analyze and interpret graphs that a partner must match with actual motion. 3. Diluting Gravity Measure the acceleration due to gravity using an air track, photogates and a motion detector. 4. Projectile Motion (open-ended lab) Using the CPO marble launcher with photogate, timer and marble, predict the range of the projectile and test their prediction. Also, prove the learned theory that complimentary angles will result in the same range on a flat ground. 5.
