Contents
Outcomes
- Pupils should understand how states of matter can be classified in terms of their characteristics e.g. compressibility, ease of flow, maintenance of shape and volume.
Specification References
- 5.7 Recall that particles in a liquid have a random motion within a close-packed structure.
- 5.8 Recall that particles in a solid vibrate about fixed positions within a close-packed regular structure.
Starter
Main Body of Lesson
