The Rock Cycle

Understand the rock cycle: rocks slowly change from one type to another over millions of years — igneous rock weathers into sediment, sediment becomes sedimentary rock, heat and pressure create metamorphic rock, and melting starts the cycle again

Lesson

Set out your lesson

Practise the bounded task in The Rock Cycle; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Sequence changes without assuming a compulsory starting point.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Printer, credit, and teaching notes

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

  • These supplied stage cards

  • Scrap paper and pencil; oral/pointing response where appropriate

Sequence

  • Read readiness and decide on support without treating prerequisite authoring as learner readiness.

  • Open Show first and explain its model.

  • Use Guided Try with support and its separate adult key.

  • Close Show and guided keys before Try, unless this Try is explicitly supported.

  • Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

  • No specimen identification, absolute dating or claim all processes require millions of years.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Rocks and Minerals supports The Rock Cycle. An adult previews and guides; this is a learning page, not a scored quiz.

Before you open

Ask the learner one fact they learned and one question they still have.

Opening this link does not save learning or assess mastery.

Check understanding

  • Describe the rock cycle as a continuous process with no beginning or end
  • Trace at least one complete path through the cycle from igneous to sedimentary to metamorphic and back
  • Explain that the rock cycle operates over millions of years through weathering, pressure, heat, and melting
“If your child saw igneous rock, sandstone, and marble side by side, could they explain how each type forms and how rocks slowly transform from one type to another in a never-ending cycle?”
