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.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.

This video reviews the benefits and drawbacks associated with growing corn to make ethanol.

This lesson guides a student inquiry into properties of the ocean's carbonate buffer system, and how changes in atmospheric carbon dioxide levels may affect ocean pH and biological organisms that depend on calcification.

This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

In this activity, students explore the way that human activities have changed the way that carbon is distributed in Earth's atmosphere, lithosphere, biosphere and hydrosphere.

This static visualization shows that the global carbon cycle is determined by the interactions of climate, the environment, and Earth's living systems at many levels, from molecular to global.

This is a long-term inquiry activity in which students investigate locations they believe harbor cellulose-digesting microbes, collect samples, isolate them on selective media, and screen them for cellulase activity. These novel microbes may be useful for the production of cellulosic ethanol. In the process they learn about plating techniques, serial dilutions, symbiotic relationships and enzyme specificity. Two methods are provided, one focusing on isolation of pure microbial strains, the other focusing on finding symbiotic communities of microbes.

A short video on the causes of ocean acidification and its effects on marine ecosystems.

This energy game activity engages students in learning about energy sources. This game demonstrates that energy, the environment, and economics are closely tied together. During the course of the game and in the discussion afterward, students learn the concepts of scarcity, opportunity cost, net energy profit, law of diminishing returns, and that availability does not mean usefulness.
