This site has everything you might want to know about surface water and things you probably didn't even imagine! Click Home to access the site in Spanish.

In this environmental science lab you will chemically test a nearby creek or pond for dissolved oxygen, pH, alkalinity, hardness and turbidity. This is a field test and will determine the water quality of standing body of water. The lab...

This thorough site delves into how we use water on an everyday basis. Ground water, surface water, domestic use, commercial use, irrigation use, are just a few of the topics described on this site. Click Home to access the site in Spanish.

The United States Geological Survey offers a complete look at water science in glossary form. Take advantage of the topic guides at the top of the site. You'll find great maps, clipart and activities centers. Click Home to access the...

This U.S. Geological Survey website features a fictious town, Dryville, and uses it to illustrate every aspect of water management that you might encounter. Click Home to access the site in Spanish.

A collection of resources--pictures, maps, data, glossary--about water and the water cycle.

This textbook chapter looks at the role of temperature in sustaining life on Earth and on weather and climate. It discusses the Earth's movements and the seasons, the circulation of the oceans, wind and weather, and the water cycle....

This interactive tutorial discusses the flow of water on the surface and below the surface. You will learn about the causes and actions of wind, and how water and wind move sediment.

Students learn about surface currents, wave characteristics, and the forces that cause tides in the World Ocean.

Using groundwater models, students will analyze whether there will be enough fresh water available for the growing human population. Students will investigate how groundwater moves, what surface water is, and how we can use water...

[Free Registration/Login may be required to access all resource tools.] Describes the sources of water pollution.

Investigate the cohesive tension on the surface of water.

In this lesson plan site, students will "Define surface tension, determine what factors affect surface tension, and collect data on how many drops of water a penny can hold."

With the exception of Earth, Europa currently appears to be the only body in the solar system which potentially harbors a global ocean of liquid water. The possibility of liquid water raises the possibility of life, as well. This NASA...

[Free Registration/Login may be required to access all resource tools.] Covers different kinds of erosion by surface water.

Is it time for high tide? Make studying the tides fun with this video. Understand the impact of gravity on the water surfaces of the earth. Take the test to see how well the information is understood.

A slideshow and a short multiple-choice quiz on the rock surface of the Earth, its water, and the gas layers that surround it.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. These two are...

Science activity demonstrates how surface tension is used to suspend a paperclip on the surface of water.

Investigate density by floating an ice cube on the surface of cooking oil and observe what happens as it melts.

This site from USGS provides several activities to help understand the interrelationships among earth surface processes, ecological systems, and human activities. Also included are links to new findings and programs concerning Earth...

In this Interdisciplinary Field Investigation learners will combine science, math, geography, creative writing and art. The setting will be a local stream (site yet to be determined, Minnehaha or Vermillion) where 150 students will...

Explore the characteristics of inclined planes while observing how drops of colored water flow down a ramp and on different surfaces.

Students investigate the effects of salinity on the formation of sea ice, and whether salt water freezes more quickly or more slowly than fresh water.
