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

Population Growth, Ecological Footprints, and Overshoot part of 2012 Sustainability in Math Workshop:Activities
Rikki Wagstrom, Metropolitan State University
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.

Sustainability Efforts on Our Campus: A Mathematical Analysis part of 2012 Sustainability in Math Workshop:Activities
Lori Carmack, Salisbury University
In these open-ended but simple activities, students use basic mathematics and descriptive statistics to analyze campus sustainability efforts.

Applying Quantitative Reasoning to Biodiversity part of Activities
Kenneth Mulder, Green Mountain College
A series of 6 Excel-based projects on the mathematics of biodiversity for basic college math classes and developmental math classes. Students learn about the structure of biodiversity, the application of many basic data analysis skills, and the use of Excel for analysis and data presentation.

One day it is too hot and other days it is too cold. Do we need to replace the HVAC system? part of 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.

Analysis of the Global Climate Change Controversy: A Problem-Based Learning Activity part of 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 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.

Arctic Sea Ice Extent part of 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.

What's for Dinner? Analyzing Historical Data about the American Diet part of 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 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.
