Science - Grade 2-3

Instructions: Read each problem carefully. Use complete sentences when you explain your thinking.
  1. 1
    Butterfly eggs, caterpillar, chrysalis, and adult butterfly.

    Put the butterfly life cycle stages in order: adult butterfly, egg, chrysalis, caterpillar.

  2. 2
    Frog eggs, tadpole, froglet, and adult frog.

    Put the frog life cycle stages in order: adult frog, tadpole, egg, froglet.

  3. 3
    Seed, sprout, seedling, and flowering adult plant.

    Put the plant life cycle stages in order: seedling, adult plant with flower, seed, sprout.
