Know that Earth has layers — a thin outer crust, a thick hot mantle, and a core at the centre — and that the inside of the Earth is extremely hot

Teaching Table
Set out your lesson
Locate crust, mantle and core and explain the limits of a layered model.
Can attend to a short explanation and respond orally, by pointing, drawing or writing; check relevant prerequisite understanding rather than assuming age proves readiness.
Check readiness rather than assuming age or source graph order establishes attainment.
Prepared passage, diagram materials are available in each step.
Open the teaching material first. Keep the adult key and check sheet separate until their named stage. No printing, purchase or external media is required for the supplied adapted text tasks.
Use the supplied text/schematic indoors. Do not collect, taste, touch or disturb wildlife or unknown materials. Discussion does not require a personal experience.
Only record a real observation after the activity is actually carried out safely; otherwise mark not carried out.
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: Know that Earth has layers — a thin outer crust, a thick hot mantle, and a core at the centre — and that the inside of the Earth is extremely hot
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: Name Earth's three main layers: crust, mantle, and core
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: Explain that the crust is thin compared to the other layers
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: State that Earth's interior is extremely hot — hot enough to melt rock
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: If {{name}} cracks open a hard-boiled egg, can they compare it to Earth and name the three layers — crust on the outside, mantle in the middle, and core at the centre?
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
Hot interior does not imply wholly molten mantle; core is predominantly metal, not melted rock.
