Kinetic Theory

At GCSE students need to be able to explain the macroscopic properties of solids, liquids and gases in terms of their microscopic structure. This includes explaining the different temperatures at which substances change state in terms of the energy changes involved and the relative strength of intermolecular forces between particles.

Many of the basic ideas will have been met by students previously, however it is important that these basic ideas are sound before they are applied to the more complex solid structures (ionic, simple molecular, giant molecular and metallic). 

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 other 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.
