Types of matter: solids, liquids and gases

Select samples from an outdoor setting. Magnify the substances to atomic level so that the particles they consist of can be seen. Sort the substances into groups based on how the particles are arranged and how they move. Classify the substances as solids, liquids or gases. For example, classify argon as a gas and ice as ...

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 ...
