States of matter and particle theory
Throughout key stages 3 and 4, students will develop an increasingly sophisticated understanding of the particle model in order to explain more complex phenomena. In Year 7 a good enough model, supported by visual and physical representations of particles, can be used to explain states of matter. This list includes practical teaching tips and a range of suggested activities and demonstrations.
The resources in this list are linked to the following topics:
- the properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure
- changes of state in terms of the particle model.

Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to health and safety and that they carry an appropriate risk assessment. Further information is provided in our Health and Safety guidance.
