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.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

This interactive follows carbon as it moves through various components of the carbon cycle.

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based on an extensive updating of U.S. Hardiness Zones using data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

In this video from the Polaris Project Website, American and Siberian university students participating in the project describe their research on permafrost.

This video is one of a series produced by the Switch Energy project. It highlights the use of biofuels as a renewable source of energy.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.

In this hands-on engineering activity, students will build a tabletop wind turbine. Students get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from one-inch PVC pipe and balsa wood (or recycled materials). The activity includes lots of good media and Web resources supporting the science content.

This interactive map allows the user to explore projected alterations of land surfaces in coastal communities, based on different scenarios of sea level changes over time.

In this activity about climate change on the Antarctic Peninsula, learners investigate environmental changes in the living and nonliving resources of Antarctic peninsula and the impact of these changes on AdÃlie penguin communities. The activity stresses the importance of evidence in the formulation of scientific explanations.
