Useful introduction to the carbon cycle with a diagram and a discussion of the effects of carbon dioxide on the greenhouse effect and global warming.

The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to...

This is the seventh lesson in a series of learning modules on the topic of climate change. In this lesson, you will learn how several important feedback loops help drive and regulate earth's unique climate system and affect climate...

In this activity, students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They will explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment.

The simulation shows the relationship between the inputs and outputs in the chloroplasts of plant, that can help explain how they convert water and carbon dioxide to glucose and water with the help of energy absorbed from light.
