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.

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

ELIMINATING TRAYS IN THE CAFETERIA: BENEFITS TO THE PLANET AND TO ECONOMIC COSTS part of 2012 Sustainability in Math Workshop:Activities
Dianne Marquart
In this activity, students will investigate the economic and environmental benefits of eliminating food trays in the cafeteria at their college.

Applying Quantitative Reasoning to Biodiversity part of Activities
Kenneth Mulder, Green Mountain College; Valorie Titus, 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.

Climate Change, Communities, and Public Planning: A Problem-Based Learning Activity part of 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.

Exploring the Sustainability of the U.S. Food System part of Activities
David Koetje, Calvin University; Amy Wilstermann, Calvin College; David Koetbye, Calvin College
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.

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.
