An animated model of the Earth from the Geophysical Fluid Dynamics Laboratory showing how global temperatures increased from 1870 to 2100 due to rising amounts of carbon dioxide in the atmosphere.

See how carbon dioxide reacts with water to produce carbonic acid.

This resource, adapted from the Carbon Dioxide Information Analysis Center, provides a graph of monthly average carbon dioxide (CO2) concentration from 1958 to 2000 at the Mauna Loa Observatory in Hawaii.

Breathing Earth layers data about rates of carbon dioxide emission along with birth and death rates onto a map of the world in a real-time simulation of one of the principal greenhouse gases in the Earth's atmosphere, CO2.

A collection of images which shows the effects of too much carbon in our atmosphere There are also some promising carbon-reducing images as well.

Take a trip in a "time machine" to see a series of pictures that show the how the climate of Earth has been changing. The indicators shown are: sea ice, sea level, carbon dioxide, and global temperature.

This lesson will introduce the Calvin cycle, and explain how it converts carbon dioxide to sugar. It is 3 of 4 in the series titled "Calvin Cycle."

This lesson will introduce the Calvin cycle, and explain how it converts carbon dioxide to sugar. It is 4 of 4 in the series titled "Calvin Cycle."

Travel through time and explore how the changing climate has affected sea ice, sea level, carbon dioxide levels, and global temperatures. Also, decide whether or not you would be affected if the sea level rose due to warmer temperatures...

Through a simple online model, students learn about the relationship between average global temperature and carbon dioxide emissions while predicting temperature change over the 21st Century.

These models show the structures of some basic molecules such as water and carbon dioxide, then move on to show more complex molecular strautures.

Examine these graphs from the NOVA/ FRONTLINE Web site to see dramatic increases in the temperature of Earth's surface and greenhouse gases in the atmosphere.

Use this interactive animation to find out about whether or not gases dissolving in water.

This lesson will introduce the Kreb's cycle and explain how it is used to convert pyruvic acid into carbon dioxide. It is 3 of 6 in the series titled "Krebs Cycle."

A PowerPoint presentation reviewing the steps in the light reaction of photosynthesis. Understand how the light reaction uses water, carbon dioxide and light energy to produce ATP.
