AC9S7U05
Official content description
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

What Year 7 Science students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 7 Science standard sentences this code builds towards:
- They identify potential ethical issues and intercultural considerations required for field locations or use of secondary data.
- They use particle theory to explain the physical properties of substances and develop processes that separate mixtures.
- They select and construct appropriate representations to organise data and information.
- They process data and information and analyse it to describe patterns, trends and relationships.
- They select and use language and text features appropriately for their purpose and audience when communicating their ideas and findings.
- They explain how scientific responses are developed and can impact society.
The Science understanding progression either side of AC9S7U05
A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
Taught before · Year 6
- AC9S6U01investigate the physical conditions of a habitat and analyse how the growth and survival of living things is affected by changing physical conditions
- AC9S6U02describe the movement of Earth and other planets relative to the sun and model how Earth’s tilt, rotation on its axis and revolution around the sun relate to cyclic observable phenomena, including variable day and night length
- AC9S6U03investigate the transfer and transformation of energy in electrical circuits, including the role of circuit components, insulators and conductors
Builds towards · Year 8
- AC9S8U01recognise cells as the basic units of living things, compare plant and animal cells, and describe the functions of specialised cell structures and organelles
- AC9S8U02analyse the relationship between structure and function of cells, tissues and organs in a plant and an animal organ system and explain how these systems enable survival of the individual
- AC9S8U03investigate tectonic activity including the formation of geological features at divergent, convergent and transform plate boundaries and describe the scientific evidence for the theory of plate tectonics
Other Year 7 Science understanding codes
- AC9S7U01investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys
- AC9S7U02use models, including food webs, to represent matter and energy flow in ecosystems and predict the impact of changing abiotic and biotic factors on populations
- AC9S7U03model 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
- AC9S7U04investigate 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
- AC9S7U06use a particle model to describe differences between pure substances and mixtures and apply understanding of properties of substances to separate mixtures
