# Drawing Particle Diagrams

Draw and interpret particle diagrams — dot representations showing the arrangement, spacing, and movement of particles in solids (close, regular, vibrating in place), liquids (close, random, flowing past each other), and gases (widely spaced, moving rapidly in all directions) — and use these diagrams to explain observable properties such as fixed shape, fixed volume, and compressibility

## Ready when they can

- Draw labelled particle diagrams for solids, liquids, and gases showing the correct arrangement and spacing of particles
- Use their particle diagram to explain why solids keep their shape but liquids flow
- Sketch what happens to particles during a change of state (e.g. melting) and explain the energy changes involved

## Lesson: Drawing particle diagrams

You have been testing and sorting materials with your hands. Everything around you, even the air, is made of tiny bits called particles, far too small to see. Scientists draw particles as dots to show how they are arranged. This kind of drawing is called a particle diagram.

*(drawing: In a solid, particles sit close together in neat, regular rows. They vibrate on the spot but do not swap places, so the solid keeps its shape.)*

In a liquid, particles are still close together, unlike solids that vibrate in neat rows. They tumble and slide past each other, so a liquid can flow and pour into any shape of container. Gas spreads far and zooms.

**Example.** Jake blows a balloon. Gas particles spread far apart and zoom everywhere. With empty space, Jake can squeeze the balloon and push particles closer.

When something melts, like ice turning to water, its particles gain energy from heat. They vibrate faster until they break free from their fixed spots and start to slide past each other, so the solid becomes a liquid! Cooling does the opposite: particles lose energy, slow down, and pack closer.

**Recap.** Particle diagrams show how close, how ordered, and how much particles move, and that tells you whether something is a solid, a liquid, or a gas.
