Changing State

Aims & Learning Outcomes

To resource the 11-14 science area ‘Materials and their Properties’ as an experimental and investigative discipline.
To provide investigations set in contexts that appeal to the target audience.
To illustrate the scientific ideas involved with the help of computer graphics, animation, real life applications and memorable demonstrations.

• To recognise differences between solids, liquids and gases in terms of properties, e.g. ease of flow, maintenance of shape and volume.
• To construct a simple model of solids, liquids and gases in terms of arrangement and movement of particles.
• To see how the particle theory of matter can be used to explain the properties of solids, liquids and gases, including changes of state.
• To recognise that different materials change state at different temperatures.
