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.

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.

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
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.

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.

Hybrid Vehicles: Are They Worth It? part of 2012 Sustainability in Math Workshop:Activities
Lori Carmack, Salisbury University
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.

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.

Conservation and Restoration in a Local Ecosystem part of Activities
David Koetje, Calvin University; Amy Wilstermann, Calvin University
Students are introduced to a local ecosystem and tasked with observing several sites, identifying features that pose threats or promote resilience at the sites, assessing the overall health of the ecosystem, and formulating recommendations for management of the ecosystem.
