Learn about the water cycle through the adventures of two sisters. They will explain how the sun powers the water cycle and describe the different states of water. A glossary and labeled illustrations accompany the video. For the...

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...

Students apply their understanding of the natural water cycle and the urban stormwater water cycle, as well as the processes involved in both cycles to hypothesize how the flow of water is affected by altering precipitation.

How do you show students that the water cycle is more than just the traditional model of the ocean, clouds, and mountains and actually a part of their daily lives? This video will show multiple models of different part of the water cycle...

Great colorful chart of the water cycle, with background information. Provides additional links for more information on the water cycle.

This ZOOMSci video segment shows how to create self-contained environments and explore how plants grow under different conditions. [3:24]

Activities demonstrate how the water cycle maintains itself.

Activity helps with understanding the water cycle.

Fourth graders will construct a model of the water cycle in action.

Create a water cycle story and storyboard.

Hyperlinked diagram provides an in-depth explanation of each phase of the Earth's water cycle.

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

Activity provides an understanding of the water cycle.

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 activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag.

For this lesson, students will explore how water is continually cycled among land, the oceans, and the atmosphere.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

To understand a bubble chamber, picture the long, white streak an airplane leaves in its wake. That's water vapor produced by condensation from the plane's hot exhaust. Until the water particles evaporate, you can follow the streak to...

[Free Registration/Login Required] This flipchart explores weather related vocabulary, including the water cycle, precipitation, condensation, evaporation, storms, and weather instruments.

An indexing page for the HyperPhysics site. This page includes links to a variety of pages at the site which contain information related to phase changes. Each individual page consists of informative graphics and clear explanations.

Educational resource invites users to understand the properties of water by first examining what water is and how we use it and then leads users to further information on the three states that water can exist.

Animation and text explain the water--or hydrologic--cycle, which is the process that water undergoes in nature.

For this investigation, students will observe and learn about the different types of clouds and be able to explain in their own words how clouds are formed. They will also observe an experiment illustrating how clouds form.

The paths that water can take through Earth's systems are many and complex. Examine the following diagram from NASA depicting the water cycle. Studying the water cycle is important because changes in the water cycle affect all parts of...
