Fast & Slow Earth Changes

ScienceVolcanoes & EarthquakesAges 5–7

Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)

Teaching Table

Set out your lesson

Compare Earth-surface changes by timescale without assuming a process is always slow.

Activity

Can attend to a short explanation and respond orally, by pointing, drawing or writing; check relevant prerequisite understanding rather than assuming age proves readiness.

Policy

Check readiness rather than assuming age or source graph order establishes attainment.

Materials

Prepared passage, cards materials are available in each step.

Preparation

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.

Safety

Use the supplied text/schematic indoors. Do not collect, taste, touch or disturb wildlife or unknown materials. Discussion does not require a personal experience.

Optional Observation

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: Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)
Bounded task opportunity only; this task samples the clause using repeated application evidence, not full coverage or learner attainment.
partial: Give an example of a quick change to Earth's surface like a volcanic eruption
Bounded task opportunity only; this task samples the clause using repeated application evidence, not full coverage or learner attainment.
partial: Give an example of a slow change to Earth's surface like erosion by wind or water
Bounded task opportunity only; this task samples the clause using repeated application evidence, not full coverage or learner attainment.
partial: Compare quick and slow changes and explain the difference
Bounded task opportunity only; this task samples the clause using repeated application evidence, not full coverage or learner attainment.
partial: If you point out a cliff being worn away by waves, can {{name}} explain that this happens slowly, while a volcanic eruption or earthquake changes the land quickly?

Canonical slow wind/water category is a simplification; erosion can be rapid.
