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.

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.
