This is a short video outlining the causes and effects of a magnitude 9.2 earthquake in Alaska in 1964. Additional resources include a background essay and discussion questions.
This animation illustrates how seismic waves travel through the earth to a single seismic station. Scale and movement of the seismic station are greatly exaggerated to depict the relative motion recorded by the seismogram as P, S, and surface waves arrive.
This animation illustrates the movement of the three basic waves associated with an earthquake and the effects of these waves on various locations. By measuring the travel time of the P and S waves, distances from the epicenter can be calculated.
In August 2008, the "Mountain Weather Workshop: Bridging the Gap Between Research and Forecasting" was held in Whistler, BC, Canada. It was sponsored by the American Meteorological Society, UCAR/COMET, and the Meteorological Service of Canada. The workshop brought together researchers, faculty, students, and operational forecasters. Its primary goals were to help provide a better understanding of the state of the science of mountain meteorology from both a research and an operational perspective, and to discuss ways of improving interaction between the research and forecasting communities. The workshop consisted of lectures by distinguished speakers covering numerous topics related to weather in complex terrain. This webcast collection contains recordings of the presentations from the workshop.
In this activity, students play a game that simulates the carbon cycle. During the activity students will compare the carbon cycle before and after the industrial revolution.
In this activity, students will work in collaborative groups to develop an advertisement for a political candidate in support of one side of an issue - should we build low-cost housing on part of the land presently occupied by an estuary? Each group will decide which side they want to support - either for or against building the housing - and write an ad that will be run in a local paper, or that will be viewed on local TV, to support their argument.
Students will examine geologic maps in order to assess the likelihood and location of earthquakes in California.
Students will examine geologic maps in order to understand how water shapes the land and is stored within the land - in part of the Grand Canyon.
In this simulation activity, students play the roles of community members wrestling with the problem of cleaning up a polluted pond on their common property. They quickly discover that because of their different values and interests, the important question is not whether to clean up the pond, but how much clean-up they are willing to pay for.
This brief classroom activity can be used to informally assess students ability to apply the principles of economic reasoning to environmental issues.
Students will use an online calculator to estimate their household's carbon footprint and explore various actions to reduce it.
The AirData website provides access to air pollution data for the entire United States. Users have the ability to produce reports and maps of air pollution data based on criteria that they specify.
The purpose of this online tutorial activity is to introduce air masses that commonly influence the weather in the United States, characteristics of these air masses, and how to identify air masses on weather maps. Key words throughout this activity link directly to helper resources that provide useful information for answering the questions.
