Animal Life Cycles
Describe differences in the life cycles of mammals, amphibians, insects, and birds, comparing metamorphosis with direct development
Lesson
Set out your lesson
“Animal Life Cycles means comparing life cycles—direct development vs metamorphosis—across mammals, birds, amphibians, and insects. We will practise once together, then check a fresh example.”
Bring to the table
- Four cards: mammal, bird, amphibian, insect
- Simple cycle sketches (baby→adult; egg→larva→adult)
Extra for the adult
Worked example. A puppy looks like a dog. A caterpillar becomes a butterfly (metamorphosis). A tadpole becomes a frog.
Optional challenge. For Animal Life Cycles, order frog stages: egg → tadpole → frog.
What to notice. Keep one parent note: sorts; metamorphosis word used; support used. This session samples life-cycle differences, not mastery of every animal.

Check understanding
- Describe the life cycle of a mammal, amphibian, insect, and bird with key stages for each
- Compare metamorphosis (complete change of form) with direct development (gradual growth)
- Identify which groups undergo metamorphosis and which do not
“Can your child explain how a butterfly's life cycle (egg, caterpillar, chrysalis, butterfly) is completely different from how a puppy grows into a dog?”
