The Mesozoic Era

CONCEPTUAL
Science›Dinosaurs & Paleontology|Ages 7—9|ID: mt_uQljqc0J5j

Place the three periods of the Mesozoic Era — Triassic, Jurassic, and Cretaceous — in order and understand that different dinosaurs lived in different periods, not all at the same time

Mastery Evidence

  • List Triassic, Jurassic, and Cretaceous in the correct chronological order
  • Assign at least one well-known dinosaur to the correct period
  • Explain that millions of years separated these periods and different species lived in each

Assessment Prompt

“Does [child] know that T. rex and Stegosaurus didn't actually live at the same time — and can they name the three dinosaur time periods in order?”

Prerequisites3

Show full prerequisite tree
  • Famous Dinosaur Species soft

    Knowing species names helps when assigning them to time periods

  • Dinosaurs Were Real hard

    Must understand dinosaurs existed long ago before placing them in geological periods

  • Dinosaur Sizes soft

    Placing the Mesozoic periods in order and understanding that different dinosaurs lived in different periods is contextualised by the prior knowledge that dinosaurs varied enormously in size — size variation across time periods supports the concept of evolutionary change
