California's Water Supply

This resource developed from KQED's QUEST, uses California’s delicately balanced watershed as an example of how the water cycle operates.

Caves and Karst

This interactive resource adapted from the National Park Service presents the key concepts of cave and karst systems, including how and where they form, different types, and various cave environments.

Clues from Past Climates

In this interactive produced by ThinkTV, learn how scientists discover clues to past climates that lie hidden in the natural environment, as well as in some surprising historical documents.

Convective Cloud Systems

This video segment adapted from the Atmospheric Radiation Program explains the differences in the formation of tropical convective cloud systems over islands and over the ocean.

Cycling Water Through the Environment

Students explore the water cycle and investigate the different forms that water can take in the environment.

Earth’s Albedo and Global Warming

In this interactive activity adapted from NASA and the U.S. Geological Survey, learn about Earth's albedo (the ratio of reflected vs. incident solar radiation), how pollution alters albedo, and how ice-albedo feedback may accelerate global warming.

Earth Water Filter

In this video segment adapted from ZOOM, cast members try to make the most effective water filter. They experiment with filtering dirty, salty water through different combinations of sand, gravel, and a cotton bandana.

Florida's Everglades: The River of Grass

In this lesson designed to enhance literacy skills, students learn about the unique environment of southern Florida's Everglades and gain insights into the interrelatedness of living things, nonliving things, and climate.

Glaciers

Featuring images of glacier formations, this interactive resource adapted from the National Park Service explains what glaciers are, where they are found, how they form, and how they move.

Global Water Distribution

How much water on Earth is fresh water? How much of that fresh water is found in icecaps? Lakes? Rivers? This interactive resource uses bar graphs to illustrate the relative distribution of fresh and salt water on Earth. Adapted from Oxford University Press.

The Great Flood of 1993

In this video segment adapted from NOVA, a meteorologist explains how an unusual weather pattern led to one of the most devastating floods of this century.

Human Impact on Water Quality

Students explore human impact on water resources, investigate the quality of their community's water supply, and consider ways to clean up and avoid further pollution.

The Hydrologic Cycle

View the five processes of the hydrologic cycle in this interactive resource adapted from NASA in which animations illustrate condensation, precipitation, infiltration, runoff, and evapotranspiration.

Ice Shelf and Ice Sheet Simulation

In this interactive activity adapted from Texas A&M University, a block of melting ice simulates ice shelves and ice sheets and their differing effects on global sea level.

Life's Little Essential: Liquid Water

Why is water necessary for life? Why is it the best and possibly only liquid to do the job? This illustrated essay from NOVA Online answers these questions, explaining why planetary scientists are on the lookout for water elsewhere in the solar system.
