Chemical sciences

This Content Descriptor from Year 3 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state

Elaborations

• observing the properties of substances and classifying them as solids (that hold their shape) or liquids (that fill the bottom of containers)
• investigating ice melting or water freezing in a sealed bag and explaining their observations
• using ice cubes, butter or chocolate to explore how changes of state involve the removal of heat or the addition of heat
• investigating how changes of state in materials used by First Nations Australians such as beeswax or resins are important for their use
• exploring how changes from solid to liquid and liquid to solid can help us recycle materials such as glass or plastics

Year 3 Science Achievement Standard

By the end of Year 3 students classify and compare living and non-living things and different life cycles. They describe the observable properties of soils, rocks and minerals and describe their importance as resources. 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. They describe how people use data to develop explanations. They identify solutions that use scientific explanations. Students pose questions to explore patterns and relationships and make predictions based on observations. They use scaffolds to plan safe investigations and fair tests. They use familiar classroom instruments to make measurements. They organise data and information using provided scaffolds and identify patterns and relationships. They compare their findings with those of others, explain how they kept their investigation fair, identify further questions and draw conclusions. They communicate ideas and findings for an identified purpose, including using scientific vocabulary when appropriate.
