Rock layers and Earth's history
Interpret cross-section diagrams of the Earth's interior, geological strata, and rock cycle; read and label layers (crust, mantle, outer core, inner core); understand that deeper layers in sedimentary sequences are older

Teaching Table
Set out your lesson
Read three different Earth diagrams without mixing their meanings.
Comfort with the particular task and communication mode; optional oral/scribed work is recorded separately.
Check the learner can access these words/materials and prerequisite ideas; historical authorship is not readiness or mastery. If not, demonstrate briefly or revisit the named prerequisite.
Use concentric Earth layers, undisturbed strata and the rock-path card. Diagrams are schematic and not to scale. No printer: view only the active learner card on screen, or an adult copies its exact prompts onto plain paper without answers. Oral pointing/dictation is an access option; record it as adapted/supported and do not claim handwriting from it. Keep adult keys/scripts separate; supply only the current stage.
Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
USGS supports interior model; rock-cycle/stratigraphic detail still needs source-specific domain review. Not a complete cycle with every pathway.
Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

Check understanding
- Label the four layers of the Earth on a cross-section diagram using the correct terms
- Interpret a diagram of sedimentary rock layers and identify which layer was deposited first
- Read a rock cycle diagram and trace the pathway of a rock from igneous to sedimentary to metamorphic
“If your child sees a cut-away diagram of the Earth, can they point to and name the different layers — and if shown stacked rock layers, can they say which layer formed first?”
