Solids, Liquids & Gases
Science · Matter & Materials · conceptual
Compare and group materials as solids, liquids, or gases based on their observable properties and behaviour
What mastery looks like
- Define solids (fixed shape, hard to compress), liquids (flow, take shape of container), gases (spread out, fill space)
- Sort at least eight everyday materials into solid, liquid, or gas categories
- Explain tricky cases like sand (solid particles) or steam (gas, not visible water droplets)
Check your understanding
Can Solids, Liquids & Gases explain the difference between a solid like ice, a liquid like water, and a gas like steam, and sort everyday things into these three groups?
