Presentation

  1. 1

    Show the caterpillars in the habitat: 'These are caterpillars. They will change.'

  2. 2

    Lay out the butterfly life cycle figures in a circle: egg, caterpillar, chrysalis, butterfly. Name each.

  3. 3

    Observe the caterpillars daily and draw what you see.

  4. 4

    When chrysalises form, move to the next figure: 'Now it is a chrysalis.'

  5. 5

    When butterflies emerge, complete the circle and point back to the egg: 'A butterfly lays eggs and the cycle starts again.'

  6. 6

    On another day, present the frog life cycle with figures and photographs.

  7. 7

    Compare the two: both start as eggs and change shape as they grow.

Extensions, easiest to hardest

  1. Sequence the cards independently and check with the control chart
  2. Draw and label a life cycle wheel
  3. Compare with the plant life cycle
  4. Learn the words larva and pupa

Control of error

The circular control chart shows the stages in order; the real butterflies show the stages directly.

Ready to move on when the child…

  • Sequences both life cycles correctly
  • Names each stage
  • Explains that the cycle repeats

Guide note

Release butterflies only in warm weather and only if allowed by the supplier's guidance. Do not collect frog eggs from the wild; some Utah amphibians are protected. Use photographs, video, or models instead.

Try “pink tower”, “tummy”, “diaper”, “grace and courtesy”, or “October”.
