Tricky Animals
Sort whales, bats, penguins, and salamanders by evidence, not looks.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 21
- Some animals try to fool you. Whales swim, but they breathe air and feed their young milk. They're mammals.
- Bats fly, but they have fur and no feathers. They're mammals too. Penguins can't fly, but their feathers make them birds.
- Salamanders look like lizards, but their moist skin makes them amphibians.
- The platypus is the wildest of all. It lays eggs, but it has fur and makes milk, so it's a mammal.
Georgia Standards of Excellence in Science:
- S5L1.a — Develop a model that illustrates how animals are sorted into groups (vertebrate and invertebrate) and how vertebrates are sorted into groups (fish, amphibian, reptile, bird, and mammal) using data from multiple sources.
