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

A quick summary of the water cycle that includes a diagram of the cycle, with links to in-depth explanations of each component of the cycle. Click "water-cycle home" to access water-cycle resources in a variety of languages.

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.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will define a mixture and understand why mixtures are different than pure substances. They will classify mixtures as homogeneous or...

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.

This U.S. Geological Survey website explains the desalinization method used by some communities to change sea water into drinking water. Click Home to access the site in Spanish.

A diagram which shows how the process of atmospheric and ocean circulation works. It features such important terms as precipitation, evaporation, sublimation, snow, accumulation, wind redistribution, melt, runoff, heat, ice flow and...
