Caterpillars and Frogspawn is a free printable Grade 3 science worksheet on using eight weeks of observations to compare two animal life cycles, aligned to NGSS performance expectation 3-LS1-1. It prints 7 questions with an answer key on its own sheet of paper, in 25 versions that each ask different questions, so no two students in the class work from the same page.

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 would you expect a beetle's cycle to include?
  2. 2. What claim does this record support?
  3. 3. What does this record not tell you?
  4. 4. Why are the two cycles different in the middle?
2.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
3.What is the right order for a chicken's life cycle?
  • A.Chick, egg, adult hen, young hen
  • B.Egg, chick, young hen, adult hen
  • C.Adult hen, chick, egg, young hen
4.A kitten is born alive rather than hatching from an egg. Does it still have a life cycle?
  • A.No, cats do not grow
  • B.Yes: birth, growth, reproduction and death
  • C.No, only animals from eggs have one
5.Why is a life cycle called a cycle?
  • A.Every stage is round
  • B.The adult makes young, and they go through the same stages again
  • C.It happens on a bicycle
6.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
7.Which four things do all life cycles share?
  • A.Eggs, wings, legs and tails
  • B.Birth, growth, reproduction and death
  • C.Flowers, seeds, fruit and leaves
