What children learn in Level 50

  • Not every life cycle looks the same! A grasshopper hatches as a nymph: a small grasshopper with no wings. It grows wings as it gets bigger. No chrysalis!
  • A ladybug changes completely, like a butterfly. Its larva looks like a tiny alligator! Then it becomes a pupa, then a ladybug.
  • Loggerhead sea turtles lay their eggs in the sand on Georgia's beaches. The hatchlings crawl to the ocean and grow up at sea.
  • Alligators live in Georgia's swamps. The mother guards her nest, then carries her hatchlings to the water, gently, in her mouth!
  • Your turn! Put a ladybug's life cycle in order.

Georgia Standards of Excellence in Science:

  • S2L1.d β€” Develop models to illustrate the unique and diverse life cycles of organisms other than humans.
