7.5 Matter

Outcomes

A student:

  • describes the observed properties and behaviour of matter, using scientific models and theories about the motion and arrangement of particles (SC4-16CW)
  • explains how scientific understanding of, and discoveries about, the properties of elements, compounds and mixtures relate to their uses in everyday life (SC4-17CW)

Content

CW1 The properties of the different states of matter can be explained in terms of the motion and arrangement of particles. (ACSSU151)

Students:

a.
describe the behaviour of matter in terms of particles that are continuously moving and interacting



b.
relate an increase or decrease in the amount of heat energy possessed by particles to changes in particle movement




c.
use a simple particle model to predict the effect of adding or removing heat on different states of matter




d.
relate changes in the physical properties of matter to heat energy and particle movement that occur during observations of evaporation, condensation, boiling, melting and freezing



e. explain density in terms of a simple particle model



f.
identify the benefits and limitations of using models to explain the properties of solids, liquids and gases CCT
