Vocabulary
Read the vocabulary terms to understand the reading better.
Amphibian
An amphibian is a cold-blooded animal that lives in water when young, but breathes air as an adult.

Life Cycle
A life cycle is the stages a living thing goes through in its life.
Animals go through stages to grow up. The stages make a life cycle. Most animals have a simple life cycle. They are born alive from their mother or hatch from eggs. Then they grow to adult size.


The life cycle of an elephant and a mouse are similar. Both are born alive from their mother. They drink milk from their mother. They look like their parents but are smaller. Both will grow up and look even more like their parents. The human life cycle is similar to that of elephants and mice.

Amphibians have more stages in their life cycle. They go through big changes. Look at the pictures that show how frogs grow and change.
