What students learn in AC9S4U02
This unit helps students build a clear, usable understanding of Sources of water and describe key processes in the water.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: 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.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- identifying everyday examples of precipitation (rain or snow), evaporation (wet washing or paint drying) and condensation of water (water droplets on a cold water bottle) identifying local water sources and exploring how they change over time, such as rain puddles that evaporate or a local creek that flows faster after rain
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- 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
- E1: identifying everyday examples of precipitation (rain or snow), evaporation (wet washing or paint drying) and condensation of water (water droplets on a cold water bottle)
- E2: identifying local water sources and exploring how they change over time, such as rain puddles that evaporate or a local creek that flows faster after rain
- E3: exploring where tap water comes from and predicting what happens to water that goes down the drain
- E4: exploring a game or simulation of the water cycle, identifying key processes and creating their own representation of the water cycle
- E5: recognising that clouds are tiny water droplets suspended in air, observing a ‘cloud in a bottle’ demonstrated by a teacher and discussing what conditions are needed for clouds to form and for rain or snow to fall
- E6: exploring First Nations Australians’ connections with and valuing of water and water resource management (teaching context)
- E7: recognising First Nations Australians’ knowledges and understandings of evaporation and how the effect of evaporation can be reduced to conserve water, such as by covering surfaces (teaching context)
- E8: considering why we are encouraged to save and recycle water, and actions people can take to reduce water consumption and waste
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- Describing what is seen without connecting it to a question, pattern or prediction.
- Using everyday words only and missing simple scientific vocabulary.
- Changing more than one thing in an investigation, which makes the comparison unfair.
