An in-depth explanation of the Earth's water cycle, including a hyperlinked diagram that provides direct access to information about each phase in the cycle.

Learn about the movement of water from Earth's surface to the atmosphere with this site. Site describes the water cycle in words and with a diagram. Also explored on the page is the distribution of Earth's global water supply.

An illustrated article helps learners understand the water cycle and the distribution of Earth's water.

Through pictures, diagrams, and charts, learn how the ocean serves as a storehouse of water.

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.

A collection of ideas for creating a science fair project on the water cycle.

The steps in the water cycle and the processes that occur are explained in this resource.

Students carry out a number of activities that demonstrate the concepts of evaporation, condensation, precipitation, and soil moisture and runoff. Then students construct a terrarium as a way to observe the water cycle. Immediately...

When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...

Did you know that your body has a built-in cooler? And it might not be what you think. Sweat is produced when you are hot, but its purpose is actually to cool your body as the water in it evaporates from your skin. In this science fair...

The USGS gives an overview of the amount of water on Earth and where it is located. It gives a few interesting facts about the Earth's supply of water. Click Home to access the site in Spanish.

Find out how much of the water on Earth is actually usable by humans, and where the rest of it is located. Learn where our water comes from and why it never runs out. Click Home to access the site in Spanish.

Create a fog chamber by rapidly expanding air in a jar in this activity. This activity uses a match in a jar to bunch water into tiny droplets.

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.

This U.S. Geological Survey website explains a variety of uses for saline water. Pie graphs and bar graphs are used to illustrate the various uses. Click Home to access the site in Spanish.

Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during...

Work samples, phenomena, assessment templates, and videos that directly address standard MS-ESS2-4: cycling of water through earth's systems.

The students will be collecting, germinating and planting seeds to show the process of plant growth. The students will be recording the information in their science journal. In addition, the students will be observing the water cycle as...

Students build a model to learn about the cycle of erosion and deposition by water and wind which deposits layer upon layer of rock, soil, and organic material to the surface.

What is groundwater? Where does it fit into the water cycle? With the aid of a simple illustration, one is able to learn more about this topic. Includes link to a true-and-false quiz.

Cloud formation results when warm, humid air rises and cools, causing the water vapor in the air to condense and form clouds. In this lesson, students will conduct an activity that demonstrates how this occurs.This lesson plan was...

A detailed overview of the Earth's atmosphere, with explanations about atmospheric properties, the structure of the atmosphere, its four layers, atmospheric processes, energy heat transfer, conduction and convection, and radiation. All...
