1 APC Physics - Mechanics Sachem North High School Syllabus William Holl Overview and Prerequisites: Any student who has successfully completed APB Physics as a junior, and is currently enrolled in either Calculus AB or BC, may register to take APC Physics in their senior year. Extensive use of differentiation and integration is required for this course. The mechanics portion of the course runs for the first two marking periods of the year, roughly from September 1 st until January 31 st (20 weeks). There is one section offered, and the enrolment varies from 12 to 25 students. Almost all of these students will opt to take the APC Physics Mechanics Exam at the end of the year. Textbook: This course utilizes FUNDAMENTAL OF PHYSICS, ninth edition, by Halliday, Resnick and Walker. The test is used for reading assignments, homework assignments and turn in quizzes. Chapters 1 through 16 are covered in the mechanics portion of the course. Please see homework assignment sheet at the end of this document. Schedule: The class meets for seven and a half periods a week. On A days the class has a single 42 minute period, and on B days a double 89 period session. This schedule allows sufficient time for lecture, practice problems, labs and evaluation on each unit. Each chapter will begin with four to five periods of lecture, with homework assignment of 3 to 5 problems due each day. One or more laboratory experiments will be performed as well. Some of the labs are quick discovery experiments, and some require a double period and complete write up. One double period of group practice session is held for each chapter, where the students will master the concepts covered during the lectures. Each chapter will culminate with a 42 minute quiz, and a double period exam is given after every two chapters.

2 Laboratory Work: Laboratory experiments will conducted in small group settings. Each group will consist of three or four students conducting hands-on experimentation. The lab period will begin with a discussion of the concepts involved and the equipment they will be allowed to use. Labs are roughly divided equally between those in which I will give fairly specific instructions, and those in which the groups will be expected to come up with their own procedures. While many of the labs require students to collect data by hand and construct traditional graphs, some labs involve data is collection using computers and interfaced sensors, such as photo-gates, motion detectors, force sensors, current readers and volt meters. At times computers are used for graphing, as are the students TI-89 calculators. Students will be expect to make observations, collect data, perform appropriate calculations and come up with conclusions. In addition, they are expected to analyze their results to determine what factors might have contributed to errors in their results, and how the experiment might be altered to eliminate these errors. Students will practice guided inquiry during several laboratory periods when they are required to develop and carry out their self-designed experiments. Likewise, almost every experiment will require students to apply their in-class learning and outside research to develop well-thought, extensive conclusions that clearly state the outcomes of the experiment, error percentages, potential sources of error and links to everyday applications. All lab reports are to be written up according to a given format. After grading they are kept on file in the students portfolio. In addition to formal labs, students are often sent to the lab tables to perform quick lab exercises that may contain open ended questions. These are approximately 30 minute procedures where students are asked to determine things like the friction between two surfaces, the resistance of a piece of wire, the net work done on a system by a falling mass, etc. Course Description and Objectives: The goal of this course is to provide the students with the equivalent of a freshman calculus based physics course in mechanics. The various tasks that students will experience in the course requires them to practice guided-inquiry by developing experiments and data taking methods that must be carried out in order to determine and/or solve complex problems and laboratory questions. Students successfully completing this course should have a strong conceptional understanding in physics,

3 and should be able to apply the concepts they have mastered to solve problems unseen by them before. Students will also be able to work efficiently in the laboratory setting and be able to take and analyze data. They will have been taught with sufficient rigor to excel on the AP Physics C Mechanics exam at a level enabling them to obtain college credit. Guided Inquiry: Throughout the course students will develop their critical thinking skills by utilizing guided inquiry and student centered learning. This is accomplished in several different ways; which include group problem sets, reading passages and a variety of laboratory work. One of the lessons that make use of student centered learning is a reading assignment that deals with RC circuits and their setup, followed by a lab that requires the students to build an RC circuit and observe/record the changes that occur in the voltage and brightness of a small light bulb wired into the circuit. Students will also develop an experiment to determine the acceleration due to gravity by varying the length of a simple pendulum. Similarly, students will build egg-droppers at the conclusion of our Impulse/Momentum unit that requires them to make use of their knowledge of impulse to successfully build the most efficient egg dropper possible. Online homework assignments also require the students to perform outside reading and learning in order to correctly solve a variety of higher level physics questions. These homework assignments are done using the website Course Grading and Evaluation: Each marking period students will receive grades based on their performance and completion of; Laboratory work % Homework % Quizzes % Practice & Turn in Problems % Exams % Single period quizzes will be given at the end of each chapter, and a double period exam at the end of each unit. Final grade for the class will be determined using the formula 40 % 1 st marking period grade, 40 % 2 nd marking period grade and 20 %
