This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This lesson is an instructor demonstration that focuses specifically on two aspects of the water cycle: evaporation and condensation. This is a well described instructor led demonstration for introducing and exploring the water cycle.

In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle.

This activity was developed to give participants an understanding of Earth's water cycle by completing a WebQuest and building a model of the water cycle.

Students observe the process of evaporation, make comparisons about the process, then construct a diagram and use it to describe the process of evaporation.
