One day it is too hot and other days it is too cold. Do we need to replace the HVAC system? part of SISL:2012 Sustainability in Math Workshop:Activities
Monika Kiss, Saint Leo University
This project will allow students to create a mathematical model to help in making decision about replacing HVAC units on a large scale.

A Monarchy Deposed: The Demise of the Monarch Butterfly part of SISL:2012 Sustainability in Math Workshop:Activities
Daniel Abel, Coastal Carolina University
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.

The Costs of Your Commute: Your Money, Your Time, and the Earth part of SISL:2012 Sustainability in Math Workshop:Activities
Charlie Buehrle, Harrisburg Area Community College-Harrisburg
This activity has students investigate their own cost, CO2 output, and time for commuting. They then compare their commute to an environmentally conscious alternative by using comparable metrics.

How Big is Your Breakfast Footprint? part of SISL:2012 Sustainability in Math Workshop:Activities
Ben Galluzzo, Shippensburg University of Pennsylvania
Calculation of a carbon footprint resulting from common breakfast choices illustrates the importance of contextualization.

Arctic Sea Ice Extent part of SISL:2012 Sustainability in Math Workshop:Activities
Bill Bauldry, Appalachian State University
Student teams investigate Arctic Sea Ice by analyzing actual data and making predictions. A worthwhile extension is to predict the first year that the Arctic Ocean will be ice free.

Climate Change, Communities, and Public Planning: A Problem-Based Learning Activity part of SISL:Activities
David Koetje, Calvin University; Amy Wilstermann, Calvin University
In this problem-based learning activity, students develop a case study that "puts a human face" on the effects of global climate change (GCC) on a particular community in the United States. Students work in teams to: discover cultural, economic, and natural features of the community; identify challenges presented by GCC; and identify options for responding to these challenges.
