AC9S2U02
Official content description
explore different actions to make sounds and how to make a variety of sounds, and recognise that sound energy causes objects to vibrate
Teach AC9S2U02 this week?
TeachKoala turns this descriptor into a complete lesson — illustrated slides with teacher notes, a differentiated activity sheet and a quiz — aligned to AC9S2U02 specifically, never an invented code. Your first lesson is free.

What Year 2 Science students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 2 Science standard sentences this code builds towards:
- They demonstrate how different sounds can be produced and describe the effect of sound energy on objects.
- Students pose questions to explore observed patterns or relationships and make predictions based on experience.
- They use everyday and scientific vocabulary to communicate observations, findings and ideas.
- By the end of Year 2 students identify celestial objects and describe patterns they observe in the sky.
- They identify ways to change materials without changing their material composition.
- With guidance, they compare their observations with those of others, identify whether their investigation was fair and identify further questions.
The Science understanding progression either side of AC9S2U02
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 1
- AC9S1U01identify the basic needs of plants and animals, including air, water, food or shelter, and describe how the places they live meet those needs
- AC9S1U02describe daily and seasonal changes in the environment and explore how these changes affect everyday life
- AC9S1U03describe pushes and pulls in terms of strength and direction and predict the effect of these forces on objects’ motion and shape
Builds towards · 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
Other Year 2 Science understanding codes
- AC9S2U01recognise Earth is a planet in the solar system and identify patterns in the changing position of the sun, moon, planets and stars in the sky
- AC9S2U03recognise that materials can be changed physically without changing their material composition and explore the effect of different actions on materials including bending, twisting, stretching and breaking into smaller pieces
