Science understanding
Biological sciences
- AC9S7U01 – investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys
- AC9S7U02 – use models, including food webs, to represent matter and energy flow in ecosystems and predict the impact of changing abiotic and biotic factors on populations
Earth and space sciences
- AC9S7U03 – model cyclic changes in the relative positions of the Earth, sun and moon and explain how these cycles cause eclipses and influence predictable phenomena on Earth, including seasons and tides
Physical sciences
- AC9S7U04 – investigate and represent balanced and unbalanced forces, including gravitational force, acting on objects, and relate changes in an object’s motion to its mass and the magnitude and direction of forces acting on it
Chemical sciences
- AC9S7U05 – use particle theory to describe the arrangement of particles in a substance, including the motion of and attraction between particles, and relate this to the properties of the substance
- AC9S7U06 – use a particle model to describe differences between pure substances and mixtures and apply understanding of properties of substances to separate mixtures
