Description

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

Sample Learning Goals

  • Describe characteristics of three states of matter: solid, liquid and gas.
  • Predict how varying the temperature or pressure changes the behavior of particles.
  • Compare particles in the three different phases.
  • Explain freezing and melting with molecular level detail.
  • Recognize that different substances have different properties, including melting, freezing and boiling temperatures.
