How Fossils Form
Explain in simple terms how fossils form: an organism dies and is quickly buried in sediment; over millions of years minerals replace the remains and the sediment turns to rock, preserving the shape

Teaching Table
Set out your lesson
Practise the bounded task in How Fossils Form; see exact limits before inferring broader coverage.
Sequence first/next/later and distinguish remains from impressions.
Exact directed source edges retained; earlier authorship is not learner attainment.
These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate
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.
Use the supplied screen cards; copying the exact task to paper is optional, not required.
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 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. 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.
No absolute formation duration assigned; canonical 'millions of years' and replacement pathway are not universal requirements. No real fossil collected.
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.

Check understanding
- Describe the basic sequence: organism dies, buried in sediment, minerals replace remains over time
- Explain why fossilisation is rare — most organisms decompose before being buried
- Use the words 'sediment', 'minerals', and 'rock' correctly when explaining
“If your child made a salt-dough fossil at school, could they explain how real fossils form underground over millions of years?”
