A Monarchy Deposed: The Demise of the Monarch Butterfly part of SISL:2012 Sustainability in Math Workshop:Activities
Monarch butterflies (scientific name: Danaus plexippus) migrate annually to forests in central Mexico from Canada and California. Those surviving the 1200 - 2800 mile migration overwinter in Mexico. In this activity, students will learn about the conservation biology of monarch butterflies, threats to their survival, the implications of their potential extinction, and ways to protect the species.

Population Growth, Ecological Footprints, and Overshoot part of SISL:2012 Sustainability in Math Workshop:Activities
In this activity, students develop and apply linear, exponential, and rational functions to explore past and projected U.S. population growth, carbon footprint trend, ecological overshoot, and effectiveness of hypothetical carbon dioxide reduction initiatives.

Hybrid Vehicles: Are They Worth It? part of SISL:2012 Sustainability in Math Workshop:Activities
In this project, students analyze the costs of gasoline nationwide. They also investigate the cost-effectiveness of purchasing a new hybrid vehicle as opposed to purchasing a new vehicle that runs solely on gasoline.
