Cells are the basic units of living things; they have specialised structures and functions (ACSSU149)

Multi-cellular organisms contain systems of organs carrying out specialised functions that enable them to survive and reproduce (ACSSU150)

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

Differences between elements, compounds and mixtures can be described at a particle level (ACSSU152)

Chemical change involves substances reacting to form new substances (ACSSU225)

Sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales (ACSSU153)

Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155)
