Students learn about the Earth's water cycle, especially about evaporation. Once a dam is constructed, its reservoir becomes a part of the region's natural hydrologic cycle by receiving precipitation, storing runoff water and evaporating...

In this teacher directed inquiry indoor lab students collect snow in a cup. They will estimate how much water will be in the cup after the snow melts. Students will then make predictions about what will happen to the cup of water. After...

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

Informational weather site highlights The Water Cycle. Discover how it works and learn more about evaporation and condensation.

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

[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...

How does energy charge when evaporation is reversed? and What powers a hurricane? are explored in this module.

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

The expansion-compression-condensation cycle of a refrigerator is discussed and explained. Understandable language but no graphics.

This animation discusses water and the water cycle in a storybook format. Condensation, evaporation, and precipitation are all covered.

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.

Learners 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...

[Free Registration/Login may be required to access all resource tools.] An introduction to the biogeochemical cycle, the water cycle. Recognize evaporation, sublimation, and condensation. Identify groundwater and runoff water supplies.

This site explores the importance of clouds and how clouds are formed. Content details common atmospheric cooling mechanisms and atmospheric stability.

In the science lab, students will create and observe the conditions necessary to make a cloud in a bottle.

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.

Five chemistry lessons about phase changes between the states of mattter complete with handouts and animations.

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]
