WATER FOR PEOPLE

1.8 billion people around the world don't have access to safe water and 2.4 billion lack access to adequate sanitation.

Water Changes Everything.

Almost a billion people live without clean drinking water. We call this the water crisis. It's a crisis because it only starts with water -- but water

Learning Objectives

  • Develop students knowledge of the importance of water in the world.
  • The student knows the cases of the water in nature (solid, liquid, gas).
  • The student knows the chemical composition of water.

Guiding Ideas

Water is the only substance that occurs naturally as a solid (ice), a liquid and a gas (water vapor). It covers about 70 percent of the Earth for a total of approximately 332.5 million cubic miles (1,386 million cubic kilometers) [source: U.S. Geological Survey]. If you're familiar with the lines "Water, water, everywhere, nor any drop to drink" from the poem "The Rime of the Ancient Mariner," you'll understand that most of this water -- 97 percent of it -- is undrinkable because it's saltwater (see illustration on next page). Only 3 percent of the world's water supply is freshwater, and 77 percent of that is frozen. Of the 23 percent that is not frozen, only a half a percent is available to supply every plant, animal and person on Earth with all the water they need to survive [source: National Geographic]

So water is pretty simple, right? Actually, there ar­e a lot of things about it that scientists still don't fully understand. And the problem of making sure that enough clean, drinkable water is available to everyone and everything that needs it is anything but simple. In this article, we'll look at some of these problems. We'll also explore exactly what plants, animals and people do with water and learn more about what makes water so special.­

Student Activities

 

Teams design a Minecraft world demonstrating the formation of water molecules, identifying the type of links in it, as well as the form of water molecule.

Students deduce the cause of the high boiling point of water.

Performance Expectations

For most of us, the idea that water could keep us from going to school, doing our job, and providing for our families is a strange one — even impossible. But for millions of women and girls around the world, that scenario is a day-to-day reality.

Opportunities, choices, and bright futures don’t stand a chance against devastating and deadly illnesses, lost productivity, and childhoods cut short.

Girls in developing countries are at a disadvantage from the start — they are more likely to suffer health problems, more likely to miss school, and more likely to marry and bear children at an early age. Water For People is on a mission to end this inequality, and we know it starts with water.
