Water, Water Everywhere

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.

The Water Cycle: Now You See It, Now You Don't

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.

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.

The Water 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.

Evaporation Investigation

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

Seasonal Change on Land and Water

In this worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.
