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 claim does this record support?
  2. 2. What stage comes after the caterpillar?
  3. 3. What would you expect a beetle's cycle to include?
  4. 4. What stage comes after the tadpole with legs?
2.Which stage of a butterfly's life cycle does most of the eating?
  • A.The chrysalis
  • B.The egg
  • C.The caterpillar
3.A tadpole grows back legs, then front legs, and loses its tail. What is happening?
  • A.It is turning into a fish
  • B.It is dying
  • C.It is changing into a frog
4.What is the right order for a chicken's life cycle?
  • A.Adult hen, chick, egg, young hen
  • B.Egg, chick, young hen, adult hen
  • C.Chick, egg, adult hen, young hen
5.How is a frog's life cycle different from a chicken's?
  • A.The young frog lives in water and changes shape before it lives on land
  • B.The frog has no eggs
  • C.The chicken changes shape completely
6.What do the life cycles of a chicken, a frog and a fish all have in common?
  • A.Each has a chrysalis
  • B.Each begins as an egg, grows, and makes young of its own
  • C.Each is born alive
7.What hatches from a fish's egg?
  • A.A caterpillar
