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.

Labs
Labs are designed to foster critical thinking skills. 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
