Compare and group materials as solids, liquids, or gases based on their observable properties and behaviour

Teaching Table
Set out your lesson
Classify matter by behaviour and explain two tricky cases.
Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.
Check readiness rather than assuming source graph order establishes attainment.
Use supplied cards; optional water and a sealed air-filled bag with adult supervision. No boiling water or hot steam. Do not use a bag near face.
Use the supplied stage cards on screen or scrap paper; adult key stays separate.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Compare and group materials as solids, liquids, or gases based on their observable properties and behaviour
Bounded objective: Classify matter by behaviour and explain two tricky cases. Selected familiar samples and stated conditions only; compressibility not physically tested. No hot steam activity.
- partial: Define solids (fixed shape, hard to compress), liquids (flow, take shape of container), gases (spread out, fill space)
State behaviours applied at stated conditions; compression not tested.
- partial: Sort at least eight everyday materials into solid, liquid, or gas categories
Eight cards classified; no actual specimen testing.
- partial: Explain tricky cases like sand (solid particles) or steam (gas, not visible water droplets)
Solid grains and vapour/mist distinctions taught then recalled.
- partial: Can {{name}} 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?
Try offers taught-content-classification for the bounded objective; it does not establish every part of the source assessment. Selected familiar samples and stated conditions only; compressibility not physically tested. No hot steam activity.
Selected familiar samples and stated conditions only; compressibility not physically tested. No hot steam activity.
