States of matter: Our warming world

Matter can exist in different states, and behave differently depending on temperature. In this resource, students investigate how heat can affect the motion and arrangement of particles, and how this may impact our world.

Let's make slime!

This resource explains how to make slime using cornflour to produce something called a non-Newtonian fluid. A non-Newtonian fluid is a substance which has properties of a liquid and a solid. This means it can flow like a liquid, but also can have a set shape. It all depends on the amount of force you apply to it. In this ...

Heat changes everything

In this learning sequence, students explore a simple particle model for matter, heat energy and thermal expansion. They apply their learning to the context of expansion and contraction of rail lines and investigate ways that this is mitigated in real situations involving rail lines. They subsequently explain this to young ...

Elliot and the Surfing Scientist: 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!

Magic tricks revealed using chemistry

Some magic tricks, such as disappearing ink or candles that won't blow out, can be explained by chemistry. In this clip, three classroom chemistry experiments demonstrate that some familiar magic tricks rely on acid-base chemical reactions, and the properties and behaviour of gases. Watch closely if you've ever wanted to ...

Elliot and the Surfing Scientist: 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.

Elliot and the Surfing Scientist: The surface tension of water

Imagine you could walk on water! Some insects can do just that. Watch as the Surfing Scientist uses a paperclip and a glass of water to demonstrate how this is possible.

Change of state – water

Students use this short resource consisting of five slides with diagrams, written explanation and voice-over to demonstrate that water can exist on either of three states: solid, liquid or gas depending on its temperature. It defines melting and boiling points. There is a two-question quiz and a summary slide.

Squeaky sand

This six minute video segment from Catalyst Two compares two beaches, one with white squeaky sand, the other with darker non-squeaky sand and their sand studied under a microscope. Dr Tim Senden attempts to shed some light on this mystery with the use of a visual model. Sand avalanches and the production of sound come into ...
