Colder and colder

This lesson is designed to consolidate students’ understanding of the particle theory of matter, particularly as it applies to changes of state. The lesson begins by viewing an animation in which the temperature decreases until it is close to absolute zero and is followed by an opportunity to consolidate students’ understanding of the behaviour and arrangement of particles in the solid, liquid and gas states.

Learning Outcomes

  • Students can place examples of temperatures on a temperature scale.

  • Students understand how the behaviour of collections of particles changes as they cool down and change state.
