Despite seventy percent of the world's surface being covered with water, there is a potential shortage of this natural resource. Only a small percentage is fresh water and much of that is inaccessible or threatened. Learn about fresh...

The Science of Water Teacher's Guide provides a number of inquiry-based activities for grades 3-5 (although it can be expanded for other grades). The guide contains science lessons that enable students to explore water, behavior of...

Colorful and informative site provides users with a comprehensive lesson on water. Discuss the forms of water, the water cycle, water conservation and more.

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles....

This interactive tour helps you to understand the journey of water to the springs. Learn about the water cycle and the Florida aquifer, supporting springs and the residents of Florida and how their activities impact the quality and...

A project based scenario where students research problems and come up with answers to a local water board's concerns over water quality in the watershed. Background information is accessible for the following topics: importance of water,...

The intricate relationship between precipitation and streamflow is illustrative of the complexity and changing nature of the water cycle. These key aspects can be investigated to help understand the water cycle. The duration and...

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of...

Discover the ins and outs of the water cycle through this collection of experiments and activities.

Students investigate water cycle processes by testing how cooling affects the rate of condensation of water vapor.

Investigate water in a warmer world. This teaching box is filled with explorations and readings that help secondary students learn how climate change is affecting the water cycle.

Dewdrop teaches the water cycle through this interactive map of rivers, oceans, groundwater, the atmosphere, and glaciers.

Activity provides an understanding of the water cycle.

A massive amount of information about groundwater. Topics covered include groundwater basics, humans and groundwater, groundwater quality, and its place in the water cycle. Includes true-and-false quiz and a Q&A section, as well as a...

Learn about the four phases of the water cycle, the ways in which watersheds are crucial to healthy water, and the best ways to manage local watersheds with this interactive lesson.

In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.
