What mastery looks like

  • Explains what 'nocturnal' means
  • Names at least 3 nocturnal animals (e.g., owl, bat, fox, hedgehog, moth)
  • Describes one feature that helps a nocturnal animal (e.g., big eyes, echolocation, whiskers)

Check your understanding

If Nocturnal Animals hears an owl hooting at bedtime, can they explain that owls are nocturnal — meaning they sleep during the day and come out at night — and that their big eyes help them see in the dark?
