Video summary

What's the difference between the three states of matter, and how does heat interact? Cool shows you how.

Australian Curriculum (v9.0) content description: Year 3 Science

Investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state
(AC9S3U04)

Australian Curriculum (v9.0) content description: Year 5 Science

Explain observable properties of solids, liquids and gases by modelling the motion and arrangement of particles (AC9S5U04)

Year 3 Achievement Standards

By the end of Year 3, students classify and compare living and non-living things and different life cycles. They identify sources of heat energy and examples of heat transfer and explain changes in the temperature of objects. They classify solids and liquids based on observable properties and describe how to cause a change of state.

Year 5 Achievement Standards

By the end of Year 5, students explain how the form and behaviour of living things enables survival. They relate the particulate arrangement of solids, liquids and gases to their observable properties.
