Climate changes have occurred throughout Earth's history, with dramatic consequences to the organisms that live there. Although some climate changes are a part of Earth's natural cycles, others are the byproduct of human activity. In this lesson, students conduct an experiment to learn about carbon dioxide levels found in four different gases. Then they reflect on carbon dioxide production on a global scale. They also look at evidence of global warming in our environment, and consider their own role in contributing to global warming.
