2 Course Descriptions for MHS Course Guide Pre-AP Physics 2 Semesters 1 Credit Grade Level: 10, 11, 12 Prerequisite: Successful completion of Geometry or concurrent enrollment in Geometry Enriched, or consent of the instructor. Course Overview: Schedule: MHS operates on an 8 period day school cycle. AP 1 Physics will meet for a 47-minute period every day. The academic calendar is from August through May giving ample time to prepare before the AP exam will be given. Text: Texas Physics, Houghton, Mifflin, and Harcourt Evaluation: Tests/experimental work 70% Quizzes, homework, in-class participation, 30% Percentages based upon district policy for grade weights. Conduct the Courses: The courses consist of 11 units, with a test at the completion of each unit. Additionally, quizzes may be used throughout a unit as a frequent check for understanding. Units generally begin with an essential question and a demonstration or two to allow the students to hypothesize and discover the physical relationships. Follow up demonstrations; group activities, and self-study extend the understandings being developed throughout the unit. Homework is assigned most nights (mostly from the primary textbook) and peer-reviewed regularly. Labs are done at a time to best reinforce the relationships and concepts currently being studied except when a lab is intended to be an inquiry inductive lab to introduce a topic. Students must check daily their school s, the class website and the Google classroom for any homework, handouts, or other materials. The class website can be found by following this link: The material is updated as need be, items may be deleted or changed depending on their value to the course. Materials 1. Graph paper composition book 2. Pencil 3. Ruler Experimental Work: Labs are placed throughout the instructional year for each course. An attempt is made to do them when they fit best in the curriculum. Lab formats will vary based on desired outcomes and difficulty of the task. Typically, 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, etc. Students are periodically allowed to create their own experimental design, but ultimately most of the lab designs must lead to the collection of data, which can be analyzed through graphical methods. Students are encouraged to graph using a spreadsheet program such as excel. 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. The report design 2

3 and format may vary from student to student, but generally each report should include sections (identified by the teacher) if not all of the following: 1. Cover page 2. Theory and/or objective 3. Hypothesis/question 4. Procedure 5. Data 6. Data analysis 7. Discussion/conclusion Students are required to keep the reports in their notebooks in case the college of their choice requires evidence, artifacts or documentation prior to awarding college credit for physics. ** Please see the list of experimental work at the end of this document Units of Study at a Glance: Pre-Ap Physics Unit 0: Basics of understanding (3 days) Unit 1: Kinematics (19 days) Unit 2: Forces (19 days) Unit 3: Work, energy, and power (15 days) Unit 4 momentum and collisions (9 days) Unit 5: Circular motion and gravitation (5 days) Unit 6: Fluid mechanics (8 days) Unit 7: Heat/thermodynamics (13 days) Unit 8: Vibrations, waves and sound (16 days) Unit 9: Electromagnetics (13 days) Unit 10: Light (10 days) Unit 11: Modern physics (13 days) Dates and length are tentative due to quantum nature of real life 3
