About this worksheet
3rd Grade Fossils: Clues to Past Life Worksheet
A fossil is what is left of a living thing from long, long ago, saved in rock. This introduction to fossils teaches the three kinds third graders meet most: shells, bones, and traces such as dinosaur footprints. A smart distractor asks whether a footprint in today's mud counts, so students learn that age and rock are part of the definition.
