Control Chart Project part of Activities

Owen Byer

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.)

Teaching Mathematics as Though Our Survival Mattered part of Activities

Martin Walker

Mathematics plays a pivotal role in helping us understand "the current human condition." This attached article provides multiple examples and is useful as a supplemental reading. A variety of math problems could also be extracted for course use.

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?

Problems for Calculus and Precalculus part of Activities

Deb Hughes Hallett

Problems on Energy and Climate for Students in Calculus I and II

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?

Population Growth, Ecological Footprints, and Overshoot part of 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.

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.

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.

Replacing Household Appliances: Refrigerator part of Activities

Krys Stave, University of Nevada Las Vegas (UNLV)

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

Energy Cost of Engine Idling part of Activities

Ben Fusaro

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

How much energy do you save by doubling insulation? part of Activities

Joseph Skufca

Students will be provided the governing equation for steady state heat transfer across a surface. They will use that equation to explore the effect of changing the insulation value on the amount of energy used.

Simple Population Space Usage part of 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 Activities

Holly Partridge

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

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.

Solar panel statistical tests part of Activities

Owen Byer

In this activity, students will determine whether there is a statistically significant difference in the number of watts of power produced on individual solar panels at Bryn Mawr College.

Arctic Sea Ice Extent part of Activities

Bill Bauldry

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.

How Big is Your Breakfast Footprint? part of Activities

Ben Galluzzo, Shippensburg University

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

The Costs of Your Commute: Your Money, Your Time, and the Earth part of 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.
