Official content description
identify sources of water and describe key processes in the water cycle, including movement of water through the sky, landscape and ocean; precipitation; evaporation; and condensation
Teach AC9S4U02 this week?
TeachKoala turns this descriptor into a complete lesson — illustrated slides with teacher notes, a differentiated activity sheet and a quiz — aligned to AC9S4U02 specifically, never an invented code. Your first lesson is free.

What Year 4 Science students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 4 Science standard sentences this code builds towards:
- They identify forces acting on objects and describe their effect.
- They relate the uses of materials to their properties.
- They identify solutions based on scientific explanations and describe the needs these meet.
- They explain the role of data in science inquiry.
- They identify key processes in the water cycle and describe how water cycles through the environment.
- By the end of Year 4 students identify the roles of organisms in a habitat and construct food chains.
The Science understanding progression either side of AC9S4U02
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 3
- AC9S3U01compare characteristics of living and non-living things and examine the differences between the life cycles of plants and animals
- AC9S3U02compare the observable properties of soils, rocks and minerals and investigate why they are important Earth resources
- AC9S3U03identify sources of heat energy and examine how temperature changes when heat energy is transferred from one object to another
Builds towards · Year 5
- AC9S5U01examine how particular structural features and behaviours of living things enable their survival in specific habitats
- AC9S5U02describe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface
- AC9S5U03identify sources of light, recognise that light travels in a straight path and describe how shadows are formed and light can be reflected and refracted
Other Year 4 Science understanding codes
- AC9S4U01explain the roles and interactions of consumers, producers and decomposers within a habitat and how food chains represent feeding relationships
- AC9S4U03identify how forces can be exerted by one object on another and investigate the effect of frictional, gravitational and magnetic forces on the motion of objects
- AC9S4U04examine the properties of natural and made materials including fibres, metals, glass and plastics and consider how these properties influence their use
