Faraday's Law and Induced Current and Electric Fields (4)
UNIT: AP C Magnetic Induction
STANDARDS: click to view
DURATION: 4 period(s)
OBJECTIVES: The student will be able to
* State and explain in words Faraday's law of induction
* Apply Faraday's law of induction to compute motional emf in simple systems (a bar moving through a magnetic field in translation, or rotation)
* State Lenz's law, and apply Lenz's law in determining the direction of induced current in simple systems
* Determine the electric field induced by a changing magnetic field for simple systems
* Explain qualitatively the operation of generators, motors, and the formation of eddy currents in solid conductor
ACTIVITIES / PROCEDURES:
* Board presentation with notes and examples
* Board presentation to document / post problems solved
* Multiple representations (graphical and algebraic)
* Use of easy / medium / difficult questions
* One-on-one teacher / student instruction during practice session
* Peer teaching / collaboration during practice session
* Demonstration(s)
* Class discussion with inquiry method
* Citation of applications meaningful to students
* Spiral using PCAs and application in future lessons
ASSESSMENT:
* Monitor proficiency during practice session
* Call on students at random or with emphasis on students who may need assistance
* Assign pre-class problem(s) on next day after practice / reflection homework assignment
MATERIALS:
* Lab equipment for demonstrations
* ActivBoard and chalkboard
* Representative AP problems
HOMEWORK:
* Pre - Read / Outline Section 31.1 - 31.6
* Post - Representative problems from textbook
NOTES:
This expansive list of objectives is grouped into the same lesson plan due to the desire to adapt the order of covering concepts to the needs of students and the school schedule. Students should read all of chapter 31 prior to the start of teaching.
