i-Tree Unit Lesson 1: Water Cycle and Weather

Lesson:

Activity Description: 

This lesson emphasizes how evaporation affects precipitation which contributes to heavy rain and storms. It lays the foundation for thinking about the ways that trees can mitigate increased weather effects in urban environments like Washington, D.C. First, students discuss their past observations of evaporation and write a hypothesis to describe this phenomenon. Next, students make entries to their lab journals based on classroom instruction of the water cycle using visuals and a NASA weather video. As a class, they label a diagram that models the stages of the water cycle. This lesson provides the context for the Evaporation Lab that will be conducted in i­Tree Lesson 2.
