You will learn the life cycle of a frog through information provided on
the Internet, literature, and observations of live animals.

Resources Needed:
* You will need a computer that is connected to the internet.

Did you know that frogs begin their lives as tiny embryos?  Through a process called metamorphosis, these eggs turn into tadpoles and eventually into frogs.  This entire 
process takes from 12 to 14 weeks.  This process is also known as the frog's life cycle.
