Curriculum content descriptions

Properties of the different states of matter can be explained in terms of the motion and arrangement of particles (ACSSU151)

Elaborations
  • explaining why a model for the structure of matter is needed
  • modelling the arrangement of particles in solids, liquids and gases
  • using the particle model to explain observed phenomena linking the energy of particles to temperature changes
ScOT terms

States of matter,  Properties of matter,  Molecular motion

Types of matter: solids, liquids and gases

Select samples from an outdoor setting. Magnify the substances to atomic level so that the particles they consist of can be seen. Sort the substances into groups based on how the particles are arranged and how they move. Classify the substances as solids, liquids or gases. For example, classify argon as a gas and ice as ...
