Lesson Plan: Voltmeters Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use voltmeters in electric circuits to measure the potential difference across a component in the circuit.
Objectives
Students will be able to
- recall that the potential difference between two points in a circuit can be measured with a voltmeter,
- recall what the circuit symbol for a voltmeter is,
- recall that voltmeters must be connected in parallel to a circuit.
Prerequisites
Students should already be familiar with
- the circuit symbols for several basic circuit components: a cell, a bulb, a buzzer, and a motor,
- how to draw and interpret single-loop circuits with one cell or battery,
- what electric potential difference is.
Exclusions
Students will not cover
- ammeters,
- how voltmeters work,
- resistors and resistance,
- ohmmeters,
- complex parallel circuits,
- why voltmeters must be connected in parallel,
