Molecules in motion

Kinetic theory is one of the 'big ideas' in science. All matter is made of atoms (often molecules), but with an enormous variety of arrangements and different motions.

These experiments lead students from the classification of solids, liquids and gases into considering why there is this variety of forms. They might build theories about the atomic structure of matter, guided by the hints given by many experiments.
