Analyze the operation of technologies that use gravitational, electric, or magnetic fields, and assess the technologies social and environmental impact; D2. Investigate, in qualitative and quantitative terms, gravitational, electric, and magnetic fields, and solve related problems; D3. Demonstrate an understanding of the concepts, properties, principles, and laws related to gravitational, electric, and magnetic fields and their interactions with matter. SPECIFIC EXPECTATIONS By the end of this unit students will: D1.

Developing Skills of Investigation and Communication D2.1. use appropriate terminology related to fields, including, but not limited to: forces, potential energies, potential, and exchange particles [C] D2.2. analyse, and solve problems relating to, Newton s law of universal gravitation and circular motion (e.g., with respect to satellite orbits, black holes, dark matter) [AI] D2.3. D2.3 analyse, and solve problems involving, electric force, field strength, potential energy, and potential as they apply to uniform and non-uniform electric fields (e.g., the fields produced by a parallel plate and by point charges) [AI] D2.4. analyse, and solve problems involving, the force on charges moving in a uniform magnetic field (e.g., the force on a current-carrying conductor or a free electron) [AI] D2.5. conduct a laboratory inquiry or computer simulation to examine the behaviour of a particle in a field (e.g., test Coulomb s law; replicate Millikan s experiment or Rutherford s scattering experiment; use a bubble or cloud chamber) [PR] D3. Understanding Basic Concepts D3.1. identify, and compare the properties of, fundamental forces that are associated with different theories and models of physics (e.g., the theory of general relativity and the standard model of particle physics) D3.2. compare and contrast the corresponding properties of gravitational, electric, and magnetic fields (e.g., the strength of each field; the relationship between charge in electric fields and mass in gravitational fields) D3.3. use field diagrams to explain differences in the sources and directions of fields, including, but not limited to, differences between near-earth and distant fields, parallel plates and point charges, straight line conductors and solenoids

2 INSTRUCTIONAL STRATEGIES Instructional strategies for this course will include, but will not be limited to: Hooks and Demos Entrance Tickets Lecture Group work / Team Assignments Computer Simulations o Full Class o Think-Pair-Share o Elbow Partners Labs and Case Study Investigations Evaluation of Real Life Scenarios These strategies will enable students to not only learn physics, but understand how it physics is involved in many aspects of day to day life and in many different career paths. Class experiences will be related to real life experiences in order to make topics relevant to students interests in their current life as well as in career or future interests.

5 SUMMARY / RATIONALE In this unit all of the specific expectations will be covered. Overall expectations will be tested during the Unit Test at the end of the unit. The students will be evaluated in three different ways: 1. Assessment for o Clarifies what good performance is o Facilitates the development of self-assessment in learning. o Used to adapt teaching to meet students needs and monitor progress o The teacher will assess how students approach problems and strategies they use while problem solving, which will make it possible for the teacher to help students overcome difficulties and misconceptions in order to improve orders. o The teacher will provide students feedback, and students will also provide each other with feedback. 2. o Students use assessment to further their own learning o Self and peer assessment o Students will be able to reflect on their own learning and identify areas of strength and need o Students will be able to set their own learning goals 3. Assessment of a. A task or an activity to measure, record and report on a student s level of achievement of specific expectations b. Summative assessment c. Tests, Exams, Performance Tasks, Oral Products, Written products. The Nelson University Preparation Text book was used and closely followed to plan this Unit and thus the plan follows closely with the specific expectations. The unit will cover approximately one textbook section per lesson, with some sections being covered in two lessons. Lessons will begin with an Entrance Ticket each day. These entrance tickets will include a simple question on the front that will activate students prior knowledge or consolidate the previous days teaching before the lesson begins. On the reverse will be a checklist of expectations. These expectations will allow students to self-assess their work, by considering expectations the teacher has defined that will be used in future summative assessments. Entrance tickets will be collected within the first 10 minutes of class by the teacher, and then the lesson will begin. Demonstrations and Hooks will be included in all lessons to help engage students and activate interest in the topic that will be discussed. Afterwards lessons will combine teaching strategies such as lecture, investigation, laboratory experiments, discussions, etc. Time will also be given for students to work on practice problems and ask questions. A classroom website is used so that students can create discussion threads, post questions and also access notes, materials and other resources from class, as well as helpful links for students that may need extra help. The teacher also posts assignment information, announcements and information for parents on the website.
