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

This detailed chemistry lesson from the U.S. Department of Energy focuses on transforming vegetable oil into biodiesel through a process of transesterification. The process described offers a good model for many chemical reaction processes that are used to produce a viable product.

This video is simple in its appearance, but it contains a wealth of relevant information about global climate models.

This video, from the US Department of Energy, shows the basics of how a PV panel converts light radiated from the sun into usable power, whether on the electric grid or off, and without emissions or the use of fossil fuels.

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.

This is an activity in which students take the role of either a car seller or a car buyer to learn about transportation energy options. Car sellers are challenged to pitch to buyers about cars with a particular fuel type while car buyers each have a specified personal and socio-economic background that must be considered when buying a car.

This short video touches briefly on the future of global energy and which energy sources best meet four energy-choice criteria: affordable, available, reliable, and clean.

This activity uses geophysical and geochemical data to determine climate in Central America during the recent past and to explore the link between climate (wet periods and drought) and population growth/demise among the Maya. Students use ocean drilling data to interpret climate and to consider the influence of climate on the Mayan civilization.

In this activity, students use a spreadsheet to calculate the net carbon sequestration in a set of trees; they will utilize an allometric approach based upon parameters measured on the individual trees. They determine the species of trees in the set, measure trunk diameter at a particular height, and use the spreadsheet to calculate carbon content of the tree using forestry research data.

An interactive visualization tool to examine geocentric seasonal and latitudinal variability in solar energy reaching Earth's surface.
