Hybrid Vehicles: Are They Worth It? part of 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.

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.

How Big is Your Breakfast Footprint? part of Activities

Ben Galluzzo, Shippensburg University of Pennsylvania

Calculation of a carbon footprint resulting from common breakfast choices illustrates the importance of contextualization.

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

Arctic Sea Ice Extent part of 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.

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

Lori Carmack, Salisbury University

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

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.

Trawl Data Exploration in Multivariable Calculus part of Activities

Kris Green, Saint John Fisher College

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.

Biking vs Driving part of Activities

Deirdre Smeltzer, Eastern Mennonite University

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

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.

How should I shower? part of Activities

Margaret Sullivan

In this activity, students will investigate the questions: What are the benefits/costs of 3 varieties of shower head types: standard, low flow, massage spray? Which would be best for a homeowner? For the university dorms?

The True Cost of Eggs: Commercial vs. Local part of Activities

Caira Bongers

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.)

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.
