Lesson Plan: Reaction Rate Chemistry • 7th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the rate of a chemical reaction and explain the effect of heat on the rate of reaction using the collision theory.

Objectives

Students will be able to

  • describe the rate of a chemical reaction in terms of the speed of reactants turning in products,
  • connect the units of rate with the measurements taken in rate experiments,
  • list the factors that affect the rate of reaction,
  • describe the collision theory and use it to explain the effect of heat on the rate of reaction.

Prerequisites

Students should already be familiar with

  • the properties of different states of matter,
  • the kinetic model of matter,
  • what happens in a basic chemical reaction,
  • basic experimental setups and apparatus.

Exclusions

Students will not cover

  • (in detail) other factors that affect rate outside of heat (temperature, concentration, pressure, surface area, catalysts, molecular orientation, etc.),
  • quantitative measurements of rate or rate equations.
