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.

Debating Three Different Areas of Sustainability: the Environmental, Social and Economic Dimensions of the Triple Bottom Line part of SISL:Activities
Ethan Samuel

What's for Dinner? Analyzing Historical Data about the American Diet part of SISL:2012 Sustainability in Math Workshop:Activities
Jessica Libertini, Johns Hopkins University
In this activity, students research the historical food consumption data from the U.S. Department of Agriculture to observe trends, develop regressions, predict future behavior, and discuss broader impacts.

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.

Salt Marshes: estimation techniques using basic algebra and geometry part of SISL:2012 Sustainability in Math Workshop:Activities
Yelena Meadows, Upper Iowa University; Sharareh Nikbakht, Appalachian State University
The activity allows for learning about salt marshes ecosystem and practicing of basic math in estimations.

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.

Analysis of the Global Climate Change Controversy: A Problem-Based Learning Activity part of SISL:Activities
David Koetje, Calvin University; Amy Wilstermann, Calvin University
This is a problem-based learning activity that guides students through a process whereby the class as a whole investigates various stakeholder perspectives on the global climate change controversy. Individual students then reflect on their own perspectives in light of what they have learned.

Exploring the Sustainability of the U.S. Food System part of SISL:Activities
David Koetje, Calvin University
This is a collaborative learning activity based on the documentaries "King Corn" and "Big River" in which students explore and propose solutions to sustainability issues associated with industrial agriculture and food systems.

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.

Learning Sustainability with Sim City part of SISL:Activities
Sybil Hill
Sim City is a computer game that has the player design a city. They become the mayor. While designing the city from ground, they can choose sustainaiblity energy options such as wind farms, geothermal, and solar. The game includes greening options and pollution factors. Teachers in a variety of disciplines can utilize this to bring their core course concepts to life.
