  • Set the goal: life cycles.

🎒 Student Actions

  • Compare the two.
  • Wonder how it changes.
  • Predict the stages.
2

Explore — Order the Cycle

10 min

Students investigate.

👩‍🏫 Teacher Moves

QUESTION 1
What are the four stages of a butterfly’s life cycle, in order?
Egg → caterpillar → chrysalis → butterfly.
QUESTION 2
What comes right after the caterpillar stage?
The chrysalis (where it changes).
QUESTION 3
Why is it called a life “cycle”?
Because it repeats — the butterfly lays eggs and the whole cycle starts again.

Going deeper? Compare two cycles.

Have students compare the butterfly’s life cycle to a frog’s (egg → tadpole → froglet → frog) and find what is alike. A printable life-cycle sheet is in the Science library.
