Electricity Unit Lesson NotesIn this unit, students will be covering electricity. The unit will cover the ideas of static charge and how electric charge works. Students will then progress into voltage, current, and resistance and ultimately discovering Ohm's Law. Students will then transition into circuits and the difference between series and parallel circuits. Lastly, students will finish off the unit with the understanding of power.Lesson #LessonQuiz1What is Static Charge?2What is Electric Force?3Static Electricity ActivityYes4What is Voltage?5Voltage Activity6What is Current?7Current ActivityYes8What is Ohm's Law?9Ohm's Law Experiment10What are Series Circuits?Yes11What are Parallel Circuits?12Series Circuit Activity13Parallel Circuit ActivityYes14Resistors in Series and Parallel Experiment15Fruit Battery Lab16Electricity Usage Project17What is Power?18Unit ReviewYes19Unit TestDec 8Why do electrons flow in a circuit?How does increasing current impact your personal safety with electricity?How are voltage, current, and resistance related?What are some relative dangers about electricity in your everyday life?What is Static Charge?Big Idea: Static charge is the stationary charge of electricityBell Activity: What does Static Charge mean?What is the history of static charge?How does charge relate to electron movement?How do we generate static?Simulation Time!What are insulators?What are conductors?How do we measure charge?What are the dangers of static electricity?Video: Gas station fireWhat is Electric Force?Big Idea: Force is the push or pull applied to an object.
