Students experiment with a solar still. In this distillation lesson, students find a simple way to use evaporation to make salty water drinkable.

How do people transport fresh water long distances to ensure everyone has access to it? The final lesson in the 10-part Fresh Solutions unit encourages individuals to design their own solution, or solutions, to that very problem. Groups...

In this interdependency learning exercise, middle schoolers respond to 6 short answer questions about water resource sharing after they read assigned textbook pages.

Students explain how to desalinate water using solar energy.  In this solar lesson students complete a lab activity and explain capillary water. 

Learners examine water shortage and the process of changing salt water to fresh water. They examine a world map, define key vocabulary terms, conduct experiments involving seeds and salt water and creating distilled water, and illustrate...

Through a fishing simulation, environmentalists discover consequences of over fishing. Afterward, they discuss how the activity relates to the impact of real-life commercial fishing. They also consider sustainability in the fishing...

Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the...

Here is a cool project about making fresh water from salt water using solar power, also known as water desalination. The apparatus is made from readily available materials, and the power source is free. As an inventive thinker, you will...

Students learn about the techniques engineers have developed for changing ocean water into drinking water, including thermal and membrane desalination. They begin by reviewing the components of the natural water cycle. They see how...

This site is from the Office of the Secretary of California. It gives background about desalination along with basic methods on how it is accomplished.

This virtual field trip for middle school students looks at aquifers and their place in the hydrologic cycle. Students learn why and how it is important to protect the source of your drinking water and some unique details about the...

Informational site describes the process of water desalination and distillation. Also provides a list of free articles to peruse for further study.

This site gives information about energy needed for desalination. It gives formulas on how to determine these figures.

Find out what can be done to clean up the world's water sources to provide safe drinking water because at least 35% of the world does not have it available to them and only 3% of the world's water is fresh.

This essay from 1994 discusses the issue of water scarcity in the Middle East. It describes the problem and proposes solutions.

World Health Organizational site provides a brief introduction into the desalination guidelines development for drinking water. Contains links to water sanitation and health as well as drinking water.

Once one of the driest countries on Earth now makes more freshwater than it needs. How can other countries learn what this nation has mastered in an effort to turn droughts around?

An article and resources for research and teaching that explains how technologies are being used to desalinate ocean waters to be used for various municipal, industrial, and domestic purposes including a means to provide fresh water to...

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.

Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution...

This U.S. Geological Survey website explains the desalinization method used by some communities to change sea water into drinking water. Click Home to access the site in Spanish.
