This activity engages learners in examining data pertaining to the disappearing glaciers in Glacier National Park. After calculating percentage change of the number of glaciers from 1850 (150) to 1968 (50) and 2009 (26), students move on to the main glacier-monitoring content of the module--area vs. time data for the Grinnell Glacier, one of 26 glaciers that remain in the park. Using a second-order polynomial (quadratic function) fitted to the data, they extrapolate to estimate when there will be no Grinnell Glacier remaining (illustrating the relevance of the question mark in the title of the module).

This video is one of a series of videos produced by the Switch Energy project. It presents the pros and cons of wind power, such as where to build, affordability, efficiency, transmission.

This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This set of activities is about carbon sources, sinks, and fluxes among them - both with and without anthropogenic components.

In this hands-on engineering activity, students 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 resource consists of an interactive table with a comprehensive list of 29 Greenhouse Gases, their molecular structures, a chart showing a time series of their atmospheric concentrations (at several sampling sites), their global warming potential (GWP) and their atmospheric lifetimes. References are given to the data sets that range from the mid-1990s to 2008.

Bell Telephone Science Hour produced this video in 1958, explaining how the production of CO2 from factories and automobiles is causing the atmosphere to warm, melting the polar ice caps, and causing the sea level to rise.

This video highlights specific climate change-related phenomena that are threatening the flora and fauna of Yellowstone National Park.

In this video, scientist Dr. Susan Prichard discusses the impact of pine bark beetles on western forests, including information on how climate change, specifically rising temperatures, is exacerbating the problem.

Two simple experiments/demonstrations show the role of plants in mitigating the acidification caused when CO2 is dissolved in water.
