Classifying Ocean Animals
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)
Suggested ages 7–9
Learning journey
Your child is diving deeper into ocean science — learning how sea creatures are classified, understanding complex ocean food webs, and exploring the different zones and features of our vast oceans.
Evidence of understanding
- 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 Classifying Ocean Animals 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?
