Dinosaur Sizes

Science · Dinosaurs & Paleontology · conceptual

Compare dinosaur sizes to familiar things — some dinosaurs were as tall as a house, others were as small as a chicken — and understand that dinosaurs came in a huge range of sizes

What mastery looks like

  • Compare the size of a large dinosaur to a familiar object like a bus or house
  • Name a very large dinosaur (e.g. Brachiosaurus) and a small one (e.g. Compsognathus)
  • Use words like 'taller than', 'longer than', 'heavier than' when comparing

Check your understanding

Can Dinosaur Sizes tell you that some dinosaurs were enormous and others were tiny — maybe using comparisons like 'as tall as a building' or 'as small as a cat'?
