Course Overview: AP Physics 1 is an algebra-based general physics course. The class meets on a modified block schedule: 45-minute daily sessions. The class meets for 16 weeks in the fall semester and 20 weeks in the spring semester for an approximate total of 180 class sessions. The class employs guided instruction to emphasize problem solving and critical thinking skills. Additionally, students explore theory and practical applications through on-line simulations, structured laboratory experiments, guided laboratory experiments, and student-formulated inquiry. In accordance with guidance from the College Board, the content for this course, including laboratory investigations and assessment, is based on six big ideas which are: Big Idea 1: Objects and systems have properties such as mass and charge. Systems may have internal structure. Big Idea 2: Fields existing in space can be used to explain interactions. Big Idea 3: The interactions of an object with other objects can be described by forces. Big Idea 4: Interactions between systems can result in changes in those systems. Big Idea 5: Changes that occur as a result of interactions are constrained by conservation laws. Big Idea 6: Waves can transfer energy and momentum from one location to another without the permanent transfer of mass and serve as a mathematical model for the description of other phenomena. These six big ideas are in turn found across ten principles that drive the scope and content of the curriculum. These principles in AP Physics 1 include: 1) kinematics, 2) dynamics, 3) energy, 4) simple harmonic motion, 5) linear momentum, 6) gravitation and circular motion, 7) rotational motion, 8) mechanical waves, 9) electrostatics, and 10) electric circuits. Grading Policy: Class Work (75%) Class work constitutes the bulk of the course grade. Class work is based on total points earned divided by total points possible. The categories are laboratory assignments, homework assignments, and quizzes weighted by factors of 2.5, 1.0 and 2.0, respectively. Students will use TI-nSpire calculator systems and need to know how to use a scientific graphic calculator (preferably TI-83, TI-84, or TI-89) to perform necessary operations on all homework, laboratory work, and assessments. Page 1 of 10 CR5: Curricular Requirement Students are provided the opportunity to spend a minimum of 25 percent of instructional time engaging in hands-on laboratory work with an emphasis on inquiry-based investigations. CR6a: Curricular Requirement The laboratory work used throughout the course includes investigations that support the foundational AP Physics 1 principles. Homework: Students will demonstrate competence with concepts by the use of short assignments ranging from 5 to 20 questions per set. Included in this section are sample problems from the textbook as well as instructor-generated questions or worksheets. In addition, the course employs internet research and, when necessary, on-line tutorials. CR5: Curricular Requirement Students are provided the opportunity to spend a minimum of 25 percent of instructional time engaging in hands-on laboratory work with an emphasis on inquiry-based investigations. Laboratory work: Approximately 30% of class time is spent in preparation, execution, and overview of laboratory assignments conducted during 90 minute sessions. The course will at times employ teacher-led laboratory experiments (demonstrations). However, these demonstrations will never count as laboratory work for students, though they may serve as a source of discussion and potential springboard for studentcentered experimental inquiry as well as serving as material for assessment. Therefore, actual laboratory assignments as designated in this syllabus (as opposed to simulations), in order to promote discovery and provide opportunity for studentcentered inquiry, are always student-driven (hands-on) and consist of either structured experiments (prescribed question and procedure), guided experiments (prescribed question, student-generated procedure), or inquiry-based experiments (studentselected question and student-generated procedure.) Students will be allowed to select and set up appropriate equipment, conduct an investigation, and collect primary data during the time provided in class. Students will write-up an individual laboratory report in ink. All completed laboratory work will be compiled in a bound composition book with the following format: I II III IV V VI VII VIII CR6b: Curricular Requirement The laboratory work used throughout the course includes guidedinquiry laboratory investigations allowing students to apply all seven science practices. Title of experiment CR7: Curricular Purpose and background Requirement Cautions or safety measures The course provides Question (or Purpose) opportunities for students to develop their communication Hypothesis (none required if purpose-driven) skills by recording evidence of Experiment their research of literature or A) Materials and Equipment (including diagrams of set-ups) scientific investigations through verbal, written, and B) Procedure (with space for alterations and observations) graphic presentations. Analysis A) Data Tables (to include errors and uncertainties) B) Graphs, Charts, or Plots (with statistical analysis including best fit lines) C) Literature values (when applicable) Conclusion A) Evaluation of hypothesis B) Errata C) Emendations of experimental design/procedures D) Extensions as proposed for further investigation or as practical applications At the conclusion of every laboratory experiment, the class will conduct a review of the experimental results. In addition to identifying errata and benefiting from peer evaluation, students will discuss any emendations to the original procedure (also as instructive for future investigations) and compare the results to literature values or “expected” results generally accepted by the scientific community. In the event of discrepancy, students are expected to provide possible reasons for said discrepancy and possible extensions of the experiment (either in scope of investigation or in genuine application of concepts studied) to tackle any unresolved issues. Assessments: During each unit, quizzes will be administered to check for understanding. Additionally, at the end of each unit or topic, a quiz is employed to assess mastery of the material as it has been presented. Though this tool serves primarily as a summative assessment, it may also serve as a formative indicator should further review of the material herein presented be necessary. Page 2 of 10 CR8: Curricular Requirement The course provides opportunities for students to develop written and oral scientific argumentation skills Binder: Students will compile a binder or folder with a collection of laboratory assignments. Included in binders are practical examinations as well as investigations from online-line tutorials, virtual laboratory work, and Critical Thinking exercises. Critical Thinking (CT) exercises are either responses to a unique discrepant event or they are reaction essays to particular articles or current events meant to engage students in application of knowledge, laboratory skills, and/or or analytical skills to consider and evaluate relevant, real-world issues.
