A computer simulator that allows students to adjust the air temperature and dew point to see what type of precipitation would fall to the ground.

This NASA video provides a nice overview of Earth's water cycle from the perspective of looking at Earth from space.

In this activity, students act as water molecules and travel through parts of the water cycle (ocean, atmosphere, clouds, glaciers, snow, rivers, lakes, ground, aquifer). Students use a diagram of the hydrologic cycle to draw the pathway they traveled.
