How Animals Have Babies

Science · Animals of the World · conceptual

Know that different animals have their babies in different ways — some lay eggs (birds, reptiles, fish, insects), some give birth to live young (most mammals) — and that babies may look like miniature adults or look very different from their parents

What mastery looks like

  • Gives examples of animals that lay eggs and animals that give birth to live young
  • Describes at least one example of a baby that looks different from its parent (e.g., tadpole/frog, caterpillar/butterfly)
  • Shows curiosity about how different animals have their babies

Check your understanding

If How Animals Have Babies sees a nest with eggs in a nature programme, can they explain that birds lay eggs and the babies hatch out, but dogs and cats have their babies born alive?
