Two Life Cycles Watched

Observations the class kept of caterpillars and frogspawn over eight weeks. WHAT WE WATCHED Butterfly: egg, caterpillar, chrysalis, adult, eggs again Frog: egg, tadpole, tadpole with legs, froglet, adult, eggs again Both started as eggs. Both grew, then produced eggs of their own. Neither adult lived past the end of the year.

  1. 1. What stage comes after the caterpillar?
  2. 2. What stage comes after the tadpole with legs?
  3. 3. What does this record not tell you?
  4. 4. Why are the two cycles different in the middle?
2.A tadpole grows back legs, then front legs, and loses its tail. What is happening?
  • A.It is changing into a frog
  • B.It is turning into a fish
  • C.It is dying
3.How is a frog's life cycle different from a chicken's?
  • A.The chicken changes shape completely
  • B.The frog has no eggs
  • C.The young frog lives in water and changes shape before it lives on land
4.Which stage of a butterfly's life cycle does most of the eating?
  • A.The egg
  • B.The chrysalis
  • C.The caterpillar
5.What is the right order for a frog's life cycle?
  • A.Frogspawn, tadpole, froglet, adult frog
  • B.Froglet, tadpole, frogspawn, adult frog
  • C.Tadpole, frogspawn, adult frog, froglet
6.What is the right order for a chicken's life cycle?
  • A.Egg, chick, young hen, adult hen
  • B.Adult hen, chick, egg, young hen
  • C.Chick, egg, adult hen, young hen
7.What do the life cycles of a chicken, a frog and a fish all have in common?
  • A.Each is born alive
  • B.Each has a chrysalis
  • C.Each begins as an egg, grows, and makes young of its own
