Lesson Plan

Describe the two types of electric charge and explain how like and unlike charges interact

State the law of conservation of charge and apply it to charging scenarios

Distinguish between conductors and insulators and explain the role of free electrons

Explain the three methods of charging — friction, conduction, and induction — and identify which applies in given scenarios

Describe the structure of the atom in terms of its charged components and explain why most matter is electrically neutral

18.1

"Electric charge is a physical property of particles or objects that causes them to attract or repel each other. Charge is denoted by the symbol q. There are two types of charge: positive and negative." "The law of conservation of charge states that the total charge in an isolated system is constant. Charge is never created or destroyed; it only moves from place to place."
