This activity guides students through building a conceptual model of how carbon dioxide affects Earth's climate
This activity focuses on the geological carbon cycle to foster student thinking on Earth systems and develop understanding of how models support and test scientific findings. It can be used to support the 2012 Holiday Lecture on Science, Earth’s Climate: Back to the Future. In this activity students learn that atmospheric composition is one of the major factors in the long-term control of Earth’s climate. They then build a model of how carbon cycles through the Earth system.
