Describes what relative humidity is, shows how it is calculated, and how it is related to evaporation and condensation.

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...

This hands-on model of the water cycle is a great culminating activity for a study of the movement of water through the environment. Completed in small groups or as a class project, it involves connecting three bottles to demonstrate the...

[Free Registration/Login may be required to access all resource tools.] Discusses water and where it occurs on Earth, gives an overview of the water cycle, and explains how the ocean is an integral part of the water cycle and is...

This site provides a comprehensive introduction to the water cycle. Students construct a model to simulate parts of the water cycle. Includes background information, links to standards, lesson plans, and assessment ideas.

This is an understandable tutorial which guides the viewer through the innovations which led up to the verification of Bose-Einstein Condensation (BEC) in 1995. Follow the "Next," link at the bottom of the page to explore the following...

Learn about the water cycle from this "book" that includes bright pictures and descriptions. Learn about precipitation, condensation, and evaporation and see examples of each phenomenon.

This lesson plan focuses on teaching students to distinguish among the evaporation, condensation,and precipitation phases of the water cycle.

This overview of liquids explores what a liquid is and how matter becomes changes into a liquid.

Learn about the different stages of the Earth's water cycle, and about processes involving water, including runoff, infiltration, and the differences between hard and soft water.

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...

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.

In this instructional activity, students will explore how water is continually cycled among land, the oceans, and the atmosphere.
