Science Curriculum AP Physics I
Course Description AP Physics 1 is the first of a two year sequence that is designed to prepare students to take the AP Physics 1 examination. This course is organized around six big ideas combining together the fundamental science principles and theories of a general physics college course. It begins by integrating the use of trigonometric functions into Algebra-Based Physics topics of mechanics, waves, sound waves and electricity. This allows students to solve problems with vectors that are oriented at arbitrary angles; rather than just parallel or perpendicular to one another. This course emphasizes problem solving in the context of the principles of physical laws and principles; as well as the ability to apply that knowledge and skill to phenomenon in either an experimental or theoretical setting. Great attention is given to strengthening and reinforcing the natural connections between the sciences and real world. Students will be involved in problem solving, inquiry-based laboratory activities on an individual, small group and large group basis. Through this process the ability to read and understand problems, break them down into their component parts and then create and present solutions will be developed. About 25% of instructional time will be spent on hands-on laboratory activities with an emphasis on inquiry-based investigations. [CR5] Much of the work done in the laboratory will include the gathering of data through low-tech and high-tech (PASCO electronic sensors) lab investigations. That data will be configured by the students using the PASCO software and then analyzed using that software as well as a number of compatible programs, including Word and Excel. Through this process both analytical techniques as well as technological capability will be developed.

Systems may have internal structure. Big Idea 2: Fields existing in space can be used to explain interactions. Big Idea 3: The interactions of and 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 object to another without the permanent transfer of mass and serve as a mathematical model for the description of other phenomena.

They will present this information a partner in class for critique, describing the inaccuracies both qualitatively and quantitatively. Assessment 13
Formative assessments are done by the teacher in order to assure that the students understand the material that has been taught. These occur during class and divide into two categories. The first category is ungraded and consists of student participation, student responses to questions, observed student-student interactions and homework completion. The second type of formative assessment is graded and consists of quizzes, based on previously discussed homework assignments; quests, which are full period assessments that check a broader set of problems at the same level of difficulty as quizzes; and reading quizzes, which check to see if students have been completing reading assignments. Altogether these assessments represent about 20-30 % of the marking period grade. Summative assessments take the form of unit tests, midterms and finals. These are all given in the same form as the AP exam; half multiple choice and half free response. The multiple choice questions are conceptual in nature while the free response section involves solving multistep problems; often taken from prior AP exams. Unit tests comprise about 50-60% of each marking period grade. The midterm and final exam each represent 10% of the full year grade; combined they equal a marking period grade. The intention is for identical summative assessments to be given to all the students in the course on the same day, regardless of their teacher. This is to encourage students to study together in groups, with or without a teacher, to advance their skill and understanding. Laboratory work is graded and typically represents about 20% of each marking period grade. The grade is divided evenly between the work done in the lab, based on teacher observation, and the lab report. 14
