This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the potential difference provided by a cell based on the amount of work it does to separate charge.

Objectives

Students will be able to

recognize that a potential difference is created by a separation of positive and negative charges,
recognize that by allowing charges to flow along conductors, a charge separation can be reduced to zero,
recall that the potential difference provided by a battery to a circuit is called its electromotive force,
use the formula .

Prerequisites

Students should already be familiar with

the idea that there are positive and negative charges,
the idea that like electric charges repel each other and opposite electric charges attract each other,
the idea that objects and materials are made of atoms,
the idea that atoms consist of positively charged nuclei and negatively charged electrons,
the circuit symbols for a cell and a bulb,
the idea that an electric current is a flow of electrons.
