"How does an individual calculate a carbon footprint? Can personal decisions alter the magnitude of a carbon footprint? How much does one person's carbon footprint really matter?

In this module students will explore the size, value and significance of personal carbon emissions. In particular, students will estimate the carbon footprint of a breakfast meal consisting of cereal, fresh berries, milk, and fruit juice. After comparing breakfast carbon emissions values with group members and the class, students will contextualize these results through analysis of the mathematical model, comparison with known carbon "sinks" and reflection on the meaning of the output."
