## [Frog Life Cycle In this unit, students explore how living things depend on their environment and one another for survival. In this lesson, students discover phenomena surrounding how frogs have different internal and external structures throughout their life cycle that enable them to survive in their environments. This page highlights components of this lesson.  ](https://www.knowatom.com/science-phenomena-videos/4th-grade-science/frog-life-cycle)
