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 ...

Lakes in Antarctica

Scientists are not complacent. We still have a lot to learn about the water cycle. The discovery of glacial lakes under the ice in Antarctica actively transporting water between reservoirs was a surprise. These lakes can be up to 3km beneath the ice sheets. The pressure of the ice above helps to melt the ice, forming lakes. ...

Properties of liquid and gas

Nitrogen gas makes up 80% of the air we breathe, and if we cool the nitrogen gas down to minus 196 Celcius and squash it down we can turn it into liquid nitrogen. This liquid takes up much less space than it did as a gas. When we warm up liquid nitrogen it will turn back into a gas and take up more room, so what happens ...

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 ...
