Unit Plan: Circuits, Voltage, and Electric Potential Energy Travis DePriest

SOL’s PH.11 The student will investigate and understand how to diagram, construct, and analyze basic electrical circuits and explain the function of various circuit components. Key concepts include: a)Ohm’s law; b)series, parallel, and combined circuits; c)electrical power; and d)alternating and direct currents

Backwards Design Worth being familiar with Importan t to know and do Endurin g Underst anding Worth Being Familiar With: Equation for power in a circuit Redox reactions Anatomy of a lightbulb Important to know and do: Recognize series and parallel circuits Build simple circuits Know criteria for a circuit Applying Ohm’s law to circuits Drawing and deciphering circuit diagrams Electric Potential/Energy Current flow in complex circuits Enduring Understanding: Circuits are used in all electrical devices and homes, and facilitate the completion of necessary/everyday tasks

Final Assessment Quiz

Reflections on Teaching Differentiated Learning –Important to understand student differences, and put them in groups that result in efficiency –External websites facilitate differentiate learning –SmartBoard should be leveraged to make engaging PowerPoints

Reflections on Teaching Collaborative Learning –All aspects of the project should support collaborative learning. –Don’t trust, or make deals with, students. –Assess students understanding to ensure they are ready for the project

Reflections on Teaching Planning for Instruction –Be prepared for change –More planning = increase in classroom management Assessment –Use a quiz as a way to hold students accountable and assess student understanding before the project –Be consistent with exit slips –Keep notes of student conversations –Get organized
