Activity in which students investigate what causes the seasons by doing a series of kinesthetic modeling activities and readings. Activity includes educator background information about how to address common misconceptions about the seasons with students.

This online calculator converts from one energy unit to another - from gallons to British thermal units (Btu), kilowatt/hours to megajoules, short tons to metric tons.

As a segment in PBS's Coping with Climate Change series, Hari Sreenivasan reports on the actions the city of Chicago is taking to mitigate climate change in an urban landscape.

This animation summarizes how oil and gas form in sedimentary ocean basins. The process starts with dead plankton (organic plant and animal material) being deposited together with mud, sand and other sediments. It describes the process of sapropel, kerogen and hydrocarbon formation.

In this lab activity, students investigate how to prepare a biofuel source for conversion to a combustible product. The activity models how raw materials are refined to process liquid fuels.

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 simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global temperatures.

This video is part of the Climate Science in a Nutshell video series. This short video looks at the effects of climate change happening right now around the globe, including: more extreme weather events, droughts, forest fires, land use changes, altered ranges of disease-carrying insects, and the loss of some agricultural products. It concludes with a discussion of the differences among weather, climate variability and climate change.

In this visualization students can explore North American fossil fuel CO2 emissions at very fine space and time scales. The data is provided by the Vulcan emissions data project, a NASA/DOE funded effort under the North American Carbon Program (NACP).

A colorful graphic that depicts the risks to the environment from different degrees of temperature rise. This graphic addresses how risks change as global mean temperature increases.
