Lesson Plan: Changes of State Science

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe and explain changes of state and identify these changes through diagrams and heating curves.

Objectives

Students will be able to

  • name and describe the processes that result in changes of state,
  • explain the processes of melting, vaporization, freezing, condensation, and sublimation,
  • describe changes of state in terms of the arrangement, attractive forces, motion, and energy of particles,
  • recognize that the mass of a substance does not change during changes of state,
  • describe what latent heat is,
  • identify states and changes in state from heating and cooling curves.

Prerequisites

Students should already be familiar with

  • solids, liquids, and gases.

Exclusions

Students will not cover

  • names of the intermolecular forces broken during changes of state,
  • changes of state other than between the solid, liquid, and gas states.
