How can you tell they’ve got it: Matter Is Made of Particles?

If they’ve got it, you’ll see things like: Describe matter as made of particles too small to see with the naked eye; Use a particle model to explain differences: particles tightly packed (solid), loosely arranged (liquid), spread far apart (gas); Use the particle model to explain a state change (e.g. heating makes particles move faster and spread apart). Or just try it together: Can your child explain that everything is made of tiny particles we can't see, and that how tightly packed they are determines whether something is a solid, liquid, or gas?

Matter Is Made of Particles

Your child knows everything is made of tiny bits too small to see. How tightly packed they are decides if something is a solid, a liquid, or a gas.

In curriculum terms

Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases

How to tell they’ve got it

Tick these off as you see them — no test required.

Use the particle model to explain a state change (e.g. heating makes particles move faster and spread apart)

Builds on

Drawing Particle Diagramsages 7–11Developing a model of matter as particles too small to see is built on the particle diagram representation

Heating & Cooling Changesages 7–9Must observe state changes before explaining them with particle model

Solids, Liquids & Gasesages 8–9Must understand observable states of matter before modelling them with particles
