Algebra, Geometry, and Trigonometry will be the mathematical tool’s used to support analytical examination of the many observations made by the student throughout the year. It’s extremely important that the student seek assistance from Mr. Hurrell if they feel uncomfortable with the required mathematical skills. By appointment, Mr. Hurrell will be available before and after school for those students seeking to improve their mathematical competences. Description AP Physics 1 and AP Physics 2, a two-year algebra based AP Physics sequence launched during the 20142015 school year by the College Board, was developed to provide student’s sufficient time to acquire an unparalleled level of conceptual understanding, by way of a student centric inquiry based learning experience. AP Physics 1 is the first element of this two year curriculum and will cover all topics found in the typical first semester college introductory physics course. AP Physics 1 will develop the skills needed to succeed not only in physics, but in the college classroom where a relentless pursuit of excellence and a confident understanding of subject matter are a must. Experimentation, at home and in the lab, will inspire observations that will be supported via physical models that the student will become familiar with during the year. Topics of study in AP Physics 1 will be: - Kinematics - Newton's laws of motion - Torque - Rotational motion & angular momentum - Gravitation & circular motion - Work, energy, and power - Linear momentum - Oscillations, mechanical waves and sound - DC circuits Laboratory investigation focused on developing critical thinking and reasoning skills, along with traditional classroom work (i.e. quizzes & exams), and a regular dose of fun (aka homework), will be the primary assessment tool used during the year. 2 Required Materials Item Textbook 3” 3-ring binder + 7 dividers 1” 3-ring binder + 7 dividers Lab Notebook Calculator Other items Description Cutnell & Johnson's Physics: 9th Edition Large 3-ring binder with 7 sections labeled: - Class syllabus - Classroom Discussion & Activities (Not including labs) - Homework - Lab Reports - Quizzes - Exams - Completed quizzes from “Quiz Bank” This binder will contain material for the whole year and will be kept at home.

Bell ringers, other classroom activities (excluding labs), and organizational skills (binder checks) will be assessed by Mr. Hurrell. Effort and correctness will be the primary concerns for these items. Laboratories will comprise a significant portion of the students learning experience. Pre-lab activities, the data collection phase, and the analysis phase including the associated write-up, will be assessed by Mr. Hurrell. Quizzes will be comprised of free response questions that closely resemble questions available to students in the online quiz bank. Students will be provided with a formula sheet (including appropriate constants) during the quizzes. Exams will be comprised of free response and multiple choice questions, which closely resemble quiz bank questions and the new College Board AP Physics 1 & 2 test design. Students will be provided with a formula sheet (including appropriate constants) during the exams. Table 3: Grading Breakdown for AP Physics 1 4 Homework Expectations Homework is the student’s opportunity to exercise concepts covered in the classroom and/or laboratory. So Mr. Hurrell can effectively assess your understanding of the concepts please show all work. Homework feedback provided by Mr. Hurrell and student follow-up are critical components of homework. On the homework due date (Day after it’s assigned): - Place completed HW in your classes IN-folder at the beginning of the class period - Make sure your name is on each piece of paper - If you have more than one piece of paper staple the pieces together - Pickup corrected HW from your classes OUT-folder which will be available the day after you turn it in - Place corrected HW in your binder Obtaining Help By appointment, Mr. Hurrell will be available before and after school for any student requiring assistance with their homework. If prior arrangements are made, Mr. Hurrell will also be available during his lunch time or planning period. 5 Lab Work Lab Notebook Students will record all laboratory investigations in their “Lab Notebook”, a 9-3/4" x 7-1/2" 100 sheet Composition notebook using a pen.

Typical entries in the Lab Notebook will be: - Lab Title - Lab Overview - Date of laboratory observations - Laboratory observations (aka data collection) - Observation notes Expectations Laboratory investigations will be used to stimulate student engagement with the physical world in a team based environment. Experimentation, making initial expectations and arguments, analyzing observations, problems solving, and presentation of these elements in an organized report, will be some of the skills exercised and sharpened in the Physics lab.
