Students explore properties of matter, and recognise the relationship between these properties and their uses in everyday contexts.
In this module, students recognise a range of models as representations of matter. They use models to communicate ideas about how matter is used in everyday contexts.
Properties of Matter
- Inquiry question: How does matter change its state?
- recognise the states of matter (solid, liquid, gas)
- classify a range of everyday materials according to their state
- explore how matter can change state
- observe matter changing state to recognise that heat energy or pressure needs to be applied or removed for the change to occur
- explore processes required for a matter to change state, for example boiling, melting, freezing, sublimation
- investigate the temperature and/or pressure required for changes in state, for example:
- melting a solid, eg metal
- changing a liquid into a solid, eg ice
- changing a solid to a gas, eg dry ice
Use of a Substance Depends on its Physical and Chemical Properties
- Inquiry question: What are mixtures used for?
- observe the result of mixing a range of substances
- participate in practical investigations to mix a range of substances to form solutions, suspensions or colloids, for example:
- dissolving carbon dioxide into water to make a carbonated drink (solution)
- mixing soil and water (suspension)
- mixing vinegar and oil to make a salad dressing (colloid)
- demonstrate safe practices when mixing a range of substances to form solutions, suspensions or colloids
- identify a range of household products as solutions, suspensions or colloids
- Inquiry question: How do the chemical properties of a substance influence its use?
- explore how the chemical properties of a range of everyday substances influence their use, for example:
- corrosive properties of acid used in cleaning products
- anti-inflammatory properties of clothing worn by electricians or firefighters
- Inquiry question: How are separation techniques applied to mixtures in everyday contexts?
- explore a range of separation techniques, for example:
- identify common uses of separation techniques, for example:
- tea straining
- chromatography in forensic testing
- distillation of salt water to form fresh water
- investigate how separation techniques are selected according to the properties of the substances being separated
