Population Growth, Ecological Footprints, and Overshoot part of 2012 Sustainability in Math Workshop:Activities

Rikki Wagstrom

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.

How Big is Your Breakfast Footprint? part of 2012 Sustainability in Math Workshop:Activities

Ben Galluzzo, Shippensburg University

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

Choosing Between Home Appliances: Benefits to the Planet and Your Wallet part of 2012 Sustainability in Math Workshop: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.

Economics of installing Solar PV panels: is it worth it to the individual? part of 2012 Sustainability in Math Workshop:Activities

Martin Walter

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.

Energy Cost of Engine Idling part of 2012 Sustainability in Math Workshop:Activities

Ben Fusaro

This is an open-ended but elementary modeling exercise about idling energy behaviors and impacts.

Simple Population Space Usage part of 2012 Sustainability in Math Workshop:Activities

Bill Bauldry

Students find current values for world and US populations, the area of Texas, and the size of the average house in the USA. Students then look at ratios to assess land usage.

Water conservation part of 2012 Sustainability in Math Workshop:Activities

Holly Partridge

Small amounts of water in one home dripping from a faucet can add up to huge monetary and resource losses

The Costs of Your Commute: Your Money, Your Time, and the Earth part of 2012 Sustainability in Math Workshop:Activities

Charlie Buehrle

This activity has students investigate their own cost, CO2 output, and time for commuting. They then compare their commute to an environmentally conscious alternative by using comparable metrics.

Who Goes There? Estimating Ocean Populations in Chincoteague Bay part of 2012 Sustainability in Math Workshop: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.

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

This project will allow students to create a mathematical model to help in making decision about replacing HVAC units on a large scale.
