Volcanos and the Atmosphere
In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...
Space Awareness
Global Warming of the Atmosphere
Scientists know the amount of carbon dioxide in the atmosphere today is higher than at any point in the last 800,000 years. Scholars learn about the amount of thermic radiation absorbed by air and what happens to the rest of the...

Oceans as a Heat Reservoir
Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...
