Lesson Plan: Electric Current Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe what an electric current is and how to determine the direction of an electric current in a circuit.
Objectives
Students will be able to
- recognize that when electrons flow in a wire, there is an electric current in the wire,
- recognize that electrons are present in the circuit all the time and that current is just the movement of these electrons,
- recall that the ampere is a unit of current.
Prerequisites
Students should already be familiar with
- the idea that objects are made up of atoms,
- the idea that an atom consists of a nucleus surrounded by electrons,
- copper and iron as metals,
- the circuit symbols for a cell and a bulb,
- categories of energy.
Exclusions
Students will not cover
- calculating the current in a wire using ,
- different types of current: direct current and alternating current,
- potential difference and sources of electric current,
- resistance,
- the differences between good and bad electrical conductors,
- the structure of metals,
- currents outside of wires,
- circuits with more than one loop or parallel circuits,
- static electricity.
