How Fossils Form
化石是如何形成的
Description
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
Mastery Evidence
- 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
Assessment Prompt
If your child made a salt-dough fossil at school, could they explain how real fossils form underground over millions of years?
