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 does this record not tell you?
  2. 2. What claim does this record support?
  3. 3. What stage comes after the caterpillar?
  4. 4. Why are the two cycles different in the middle?
2.Why is a life cycle called a cycle?
  • A.It happens on a bicycle
  • B.The adult makes young, and they go through the same stages again
  • C.Every stage is round
3.Which stage of a butterfly's life cycle does most of the eating?
  • A.The caterpillar
  • B.The egg
  • C.The chrysalis
4.What hatches from a fish's egg?
  • A.A tiny larva that grows into a young fish
  • B.A caterpillar
  • C.A tadpole
5.Which four things do all life cycles share?
  • A.Flowers, seeds, fruit and leaves
  • B.Birth, growth, reproduction and death
  • C.Eggs, wings, legs and tails
6.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
7.A kitten is born alive rather than hatching from an egg. Does it still have a life cycle?
  • A.No, only animals from eggs have one
  • B.Yes: birth, growth, reproduction and death
  • C.No, cats do not grow
