Lesson Plan: Law of Levers Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify the force arm and resistance arm of a lever and investigate, describe, and use the law of levers.
Objectives
Students will be able to
- define and identify the resistance arm and force arm of a lever,
- identify the units of measurement of the resistance arm and force arm,
- identify the units of the effort force and resistance force,
- describe and investigate the law of levers using a spring balance,
- perform calculations using the law of levers.
Prerequisites
Students should already be familiar with
- forces,
- the definition of a lever,
- describing and identifying the weight force, resistance force, and fulcrum in a lever,
- multiplying and dividing numbers up to two digits long.
Exclusions
Students will not cover
- the term moments as it relates to forces,
- mechanical advantage.
