This video describes the effect of a warming climate on the tundra biome and specifically the impacts of changing climate on the Rocky Mountain Pika, a small rodent that struggles with summer heat.

The heart of this activity is a laboratory investigation that models the production of silicon. The activity is an investigation of silicon: the sources, uses, properties, importance in the fields of photovoltaics (solar cells/renewable energy) and integrated circuits industries, and, to a limited extent, environmental impact of silicon production.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.

This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the atmosphere.

This activity addresses naturally occurring climate change involving ENSO (El-NiÃo Southern Oscillation). In this activity, students play the role of a policy maker in Peru. First, they determine what sort of ENSO variation is occurring. Then, they must decide how to allocate Peru's resources to manage for possible weather-related problems.

In this lesson, students examine and interpret varied observational datasets and are asked to determine whether the data supports or does not support the statement: climate change is occurring in Colorado.

In this activity, students construct a Global Warming Wheel Card, a hand-held tool that they can use to estimate their household's emissions of carbon dioxide and learn how they can reduce them. One side of the wheel illustrates how much carbon dioxide a household contributes to the atmosphere per year through activities such as driving a car, using energy in the home, and disposing of waste. The other side shows how changes in behavior can reduce personal emissions.

This is an animated interactive simulation that illustrates differential solar heating on a surface in full sunlight versus in the shade.

This audio slideshow examines the changes in the ecosystem that will occur to the Arctic due to increasing temperatures and disappearing sea ice.

This series of visualizations show the annual Arctic sea ice minimum from 1979 to 2010. The decrease in Arctic sea ice over time is shown in an animation and a graph plotted simultaneously, but can be parsed so that the change in sea ice area can be shown without the graph.
