What Is a Fossil?
Tell fossils (remains or marks of past life in rock) from things that aren't fossils.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 21
- Welcome, Fossil Finders! A fossil is the remains or marks of a living thing from long, long ago, kept in rock.
- Fossils can be hard parts, like bones, teeth, and shells. They can also be marks a living thing left, like a footprint or a leaf print.
- A seashell on the beach today isn't a fossil. It's from today, not long ago, and it isn't in rock.
- A plastic dinosaur isn't a fossil either. It was never alive!
Georgia Standards of Excellence in Science:
- S3E2.a — Construct an argument from observations of fossils (authentic or reproductions) to communicate how they serve as evidence of past organisms and the environments in which they lived.
