In this Grade 3 environments worksheet, students read fossil clues to rebuild ancient landscapes. Palm fossils in the Arctic, fish fossils in deserts, and coral on mountains all become evidence of warmer seas, wet swamps, and shifting climates. Nine focused fill-ins plus a four-way matching puzzle build Grade 3 vocabulary like climate, extinct, and environment, pushing students to reason like real scientists about how Earth's habitats have changed.
Style:
Fossils and Evidence of Past Life
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 3 science, a palm tree fossil found in the Arctic shows the climate was once warm there.
2. In Grade 3 science, a fish fossil in a dry desert tells us a sea once covered that land.
3. In Grade 3 science, fern fossils in coal suggest the area was once a warm, wet swamp.
4. In Grade 3 science, dinosaur bones found in a backyard prove that dinosaurs once lived there.
5. In Grade 3 science, coral fossils on a mountain show the peak was once under the ocean.
6. In Grade 3 science, plants and animals that no longer live on Earth are called extinct.
7. In Grade 3 science, fossils show us how Earth's environment has changed over many millions of years.
8. In Grade 3 science, mammoth fossils in icy ground suggest the area had a very cold climate.
9. In Grade 3 science, layers of rock with fossils are read like pages of Earth's history book.
Part B: Matching
