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

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

In this activity, students use a physical model to learn the basics of photosynthesis and respiration within the carbon cycle.

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

This visualization illustrates the carbon cycle throughout the oceanic zones, beginning at the surface and traveling to the deep. The concept map-like connections encourage students to link the abiotic and biotic interactions within the oceanic food web.

This short investigation from Carbo Europe explores how temperature affects the solubility of carbon dioxide in water.

This interactive graphic outlines the carbon cycle, with clickable text boxes that explain and elaborate each component.

In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.

A simplified representation of the terrestrial carbon cycle side by side with the ocean carbon cycle. Fluxes and reservoirs expressed in gigatons are included.

This video describes the foundation Plant for the Planet, a foundation created by a 9-year-old German boy, Felix. This foundation has planted more than 500,000 trees in Germany, which he says help sequester carbon and reduce greenhouse gas emissions. The student rallies, first his community and then other children, to plant millions of trees to offset our energy-use emissions.
