Life Cycle of a Frog

Did a frog always look like this?

What is your hypothesis?

4 stages
4 stages
  • A frog goes through many changes during its lifecycle.
  • Changes are called metamorphosis.

Stage 1: Egg

Stage 2: Tadpole

Stage 3: Young Frog or Froglet

Stage 4: Adult Frog

stage 1 egg
Stage 1 - Egg
  • The first stage in the life cycle of the frog is the egg.
  • A frog lays many eggs at one time.
  • The eggs are covered with a jellylike coating.
