  • Students will describe the three states of matter.
  • Students will analyze changes of state graphically.
  • Students will ascertain the melting and boiling points of different substances.


  • absolute zero
  • boiling point
  • change of state

  • solid

About the Lesson

In this lesson, students will see the behavior of particles in a substance as the temperature changes.

As a result, students will:

  • Understand the behavior of particles as substances change state.
  • Identify the melting and boiling points of three substances by reading a graph.
