      Lesson details

      Learning outcome

      I can describe the stages in the life cycle of different mammals.

      1. Mammals are animals, they are living things that grow and reproduce
      2. Life cycles of different mammals can be observed over time and/or researched using secondary sources of information
      3. Scientific diagrams are used to show the stages in a mammal’s life cycle
      4. Mammals are born alive from their mother
      5. The stages of a mammal’s life cycle are baby, young and adult

      Keywords

      • Mammal - A mammal is a warm-blooded animal that gives birth to live young and has hair or fur.

      Teacher tip

      Encourage children to research an animal that they are personally interested them and give them opportunities to share their findings and interesting facts with their peers.
