Classifying Ocean Animals

海洋动物分类

Description

Classify ocean animals into major groups: fish (breathe through gills, have scales), marine mammals (breathe air, warm-blooded, feed milk), and invertebrates (no backbone — jellyfish, octopuses, crabs, starfish)

Mastery Evidence

✓ Sort ocean animals into fish, marine mammals, and invertebrates
✓ Give defining features of each group (gills vs lungs, backbone vs none)
✓ Correctly classify at least two animals in each group

Assessment Prompt

If your child saw pictures of a tuna, a seal, and a jellyfish, could they sort them into fish, marine mammals, and invertebrates, and explain what makes each group different?
