From Tiny Egg to Hopping Frog!

Did you know a frog does not start out looking like a frog at all? It begins life in the water as a tiny wriggling swimmer called a tadpole!

In this lesson you will follow a frog through its whole life — its life cycle. You'll build the stages, grow a tadpole yourself, and become a frog expert. 🌿
