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.
