  1. Life Cycle of a Frog Grade 3

  2. Metamorphosis • Metamorphosis is the changes that a frog goes through during its life cycle. • There are four main stages in the life cycle of the frog.

  3. 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.

  4. Tadpole • The second stage of the frog life cycle is the tadpole. • Hatched tadpoles have gills for breathing in the water. • They have a tail, but no legs.

  5. As a tadpole grows, lungs begin to form. • Back and front legs begin to grow. These parts allow the adult frog to live on land.

  6. Adult Frog • Once the lungs form and begin to work, the gills and tail disappear. • The adult frog is now ready to live on land.
