Sustainability and Changing Rates of Change
Christopher Coughenour, The Evergreen State College
To understand sustainability, students must understand rates of change. This activity includes a primer on basic rates concepts and an exercise that motivates critical thinking about rates of change and sustainability with an analysis of historical petroleum production rates data from the United States and the world.

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

Learning Sustainability with Sim City
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.

Developing a Transportation Survey to Estimate Gasoline Use by Campus Commuters
Steven Bogart, Shoreline Community College
Through this activity, students in a liberal arts mathematics class will develop experience with real-world statistical concepts through the context of sustainability: estimation, survey writing, sampling techniques, and data analysis.

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

Coriolis Effect Activity
Laura Wetzel, Eckerd College
The Coriolis Effect is the deflection of moving objects when they are viewed in a rotating reference frame. In oceanography, we are most interested in how the Coriolis Effect moves winds and ocean currents on the ...

Control Chart Project
Owen Byer, Eastern Mennonite University
This is a short assignment that asks students to find some data related to sustainability and determine whether the mean of that data set is statistically stable, and whether the process being measured is in control or out of control. It is often used for quality control in a production process, but in this activity, it is used to see if an ecosystem process is stable and healthy or disrupted (out of control.)

Population Growth, Ecological Footprints, and Overshoot
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.

Salt Marshes: estimation techniques using basic algebra and geometry
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.

Hybrid Vehicles: Are They Worth It?
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.
