Predicting Next Year's Population part of Activities

Bill Bauldry

Students use current population factors to predict the next five years' population for a chosen country.

The True Cost of Energy part of Activities

Daniel Flath

How much would it add to the cost of burning a light bulb for a year if you pay for damage to the environment, climate effects, and health harms created by using coal to generate the electrical energy?

Bakken Oil From Shale, Greenhouse Gas Emissions, and Global Oil Economics part of Activities

Robert McConnell

Students work with oil production data to assess the environmental impact, and economic controls, of oil production and consumption.

Who Goes There? Estimating Ocean Populations in Chincoteague Bay part of Activities

Maria Hernandez; Itnuit Janovitz-Freireich

In this activity students use data to: rank species on the food chain, compute energy flow ratios and estimate fish populations in the Chincoteague Bay. Students also discuss the impact of the ecosystem and humans on this population, with an extension activity calculating the biodiversity of the system.

Biking vs Driving part of Activities

Deirdre Smeltzer, Eastern Mennonite University

How much difference would biking to work one day per week make?

How Biodiverse is Lake Superior? An exercise in proportions. part of Activities

Stephanie Kajpust

Students use critical thinking and algebra to measure and evaluate the biodiversity in Lake Superior.

Salt Marshes: estimation techniques using basic algebra and geometry part of 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.

Trawl Data Exploration in Multivariable Calculus part of Activities

Kris Green

This activity is based on exploring the data collected from all trawls around the Chincoteague Bay from 2005 - 2014. Students can construct their own contour diagrams as they cross section the data based on their own choices. This database could also be used to support similar activities in statistics or graph theory.

Fitting and Estimating Rates of Change in the Functions Underlying Earth's Bio-Development Over Time part of Activities

Alan Ableson; Jennifer Bready

What is happening in our world? How has the temperature changed? Have oxygen and carbon dioxide levels changed? How does this effect biodiversity? In this lab, we will investigate the changes in these four variables over various time periods to see how they relate.

Estimating OUR Carbon Footprint part of Activities

Ben Galluzzo, Shippensburg University of Pennsylvania; Jean McGivney-Burelle; Rikki Wagstrom, Metropolitan State University

Description here.

Hybrid Vehicles: Are They Worth It? part of Activities

Lori Carmack

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.

Sustainability Efforts on Our Campus: A Mathematical Analysis part of Activities

Lori Carmack

In these open-ended but simple activities, students use basic mathematics and descriptive statistics to analyze campus sustainability efforts.

Shift in life expectancy part of Activities

Holly Partridge

Determining the shift in expected life span over a century and the social and environmental impact

Population Growth, Ecological Footprints, and Overshoot part of 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.

Choosing Between Home Appliances: Benefits to the Planet and Your Wallet part of Activities

Corri Taylor, Wellesley College

Students research various options for new appliances and make purchasing decisions based not merely on purchase price, but also on energy efficiency, which has implications for the planet AND for longer-term personal finances. Students calculate the "payback period" for the more energy efficient appliance and calculate long-term savings.

A Monarchy Deposed: The Demise of the Monarch Butterfly part of 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.

Plastic Waste Production part of Activities

Karen Bliss

In this exercise, students will use data to predict the amount of plastic waste in the next ten years.

Control Chart Project part of Activities

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.)

Economics of installing Solar PV panels: is it worth it to the individual? part of Activities

Martin Walter, University of Colorado at Boulder

We show that it is economical for an individual to install solar photovoltaic panels in Denver, Colorado; and this is a sustainable strategy for society at large.

Replacing Household Appliances: Refrigerator part of Activities

Krys Stave, University of Nevada-Las Vegas

In this problem, students compare the energy use of their existing refrigerator with a new refrigerator.
