Solids, liquids and gases have different observable properties and behave in different ways (ACSSU077)

Elaborations
  • recognising that substances exist in different states depending on the temperature
  • observing that gases have mass and take up space, demonstrated by using balloons or bubbles
  • exploring the way solids, liquids and gases change under different situations such as heating and cooling
  • recognising that not all substances can be easily classified on the basis of their observable properties

Teacher resource

Primary Connections: What's the matter?

This comprehensive teacher resource explores the properties of solids, liquids and gases through a series of collaborative inquiry-based learning activities. Students are supported to plan and conduct an investigation of whether the observable properties of materials change with temperature. Seven structured lessons are ...

Interactive Resource

experiMENTALS: Spooky slime

This resource contains a materials and instruction list and brief explanation for students about the process of making spooky slime with cornflour to produce a substance that is a little like a liquid and a little like a solid.

Interactive Resource

DIY Lava Lamp

This resource contains lessons plans containing instructions and teachers' notes for an activity based on a chemical reaction that occurs when a soluble aspirin tablet dissolves and the fact that oil and water do not mix are used to create a model of a lava lamp. Students have fun while they learn about density of fluids. ...

Properties and behaviour of gases

All substances are made up of tiny particles. A change in temperature can change the way these particles behave. Watch as the Surfing Scientist demonstrates how a gas behaves when it is heated. Find out whether the balloon gets sucked or pushed into the bottle!

Science Talk 2007: Ruben Meerman

Find out what happens when the ABC's Surfing scientist, Ruben Meerman visits Year 3 at Crown Street Public School with some liquid nitrogen! Ruben shows the Year 3 students what happens to solids and gases when they are cooled and warmed and relates this to real-world phenomena. Ruben also shows the kids some tricks with ...

Change of state: liquid to gas

Substances exist in different states depending on the temperature. Watch the Surfing Scientist have a popping good time as he demonstrates this phenomenon. Don't forget to block your ears!

Teacher resource

Heating and cooling

Students explore the properties of solids, liquids and gases, with a particular focus on the properties of air. Students investigate how heating and cooling may or may not change the state of a particular substance. The tasks allow students to articulate their thinking and record ideas.

Teacher resource

Solids, liquids and gases

This is a unit of work designed to help students increase their understanding of solids, liquids and gases, and examines in detail the observable properties and behaviours of gas. Students use this learning to help them classify different substances and identify ways in which gases are used in their everyday lives. Additional ...

From chocolate buttons to magic patterns

Want to do a simple science experiment that works just like a magic trick? Watch the Surfing Scientist to find out how. He creates a pattern made up of regular shapes by dissolving coated chocolate buttons.

Teacher resource

The particle model

Two graduate teachers collaboratively teach a lesson on the interaction of particles in solids, liquids and gases. They encourage students to take on leadership roles in class through a role-play activity to demonstrate their understanding of the particle model. Following this, students develop presentations using information ...

Teacher resource

Animating Science

Over a series of lessons with year 5 and 6 students, two graduate teachers use experiments and information and communication technology (ICT) to teach the students about the properties of solids, liquids and gases. Students are encouraged to demonstrate their knowledge of how particles behave by developing computer animations ...

Salt water density experiment

Discover what density is and how you can test the density of liquids. You will also find out about salt water and how its density is responsible for the circulation of water around the world's oceans.

Bubbles in boiling water

Have you ever wondered why boiling water has bubbles? Discover with Dr Karl how the bubbles form, then watch what happens as Ruben the Surfing Scientist adds coffee to water he has boiled without bubbles. Spectacular, but dangerous!

Shrinking and expanding metals

Explore with the Surfing Scientist team what happens when metals are heated and cooled. Find out what happens to a metal ring when it is immersed in extremely cold liquid nitrogen. What do hinges on the Sydney Harbour Bridge have to do with all this? Find out.

Teacher resource

Problems with classifying solids, liquids and gases

This teacher resource lists critical teaching ideas about states of matters and explains that classifying matter as a solid, liquid or gas is useful, although not without difficulties. It explores the differences between students' early understandings about solids, liquids and gases and the scientific view, including misunderstandings ...

Animating the particle model

A lead teacher and University education specialist discuss the implementation of a program between the school and the University to support the development of graduate teachers in delivering a science unit of work to year 5 and 6 students. The program focuses on students developing a story board to explain the particle ...
