Measuring specific gravity to answer questions about subduction. part of Quantitative Skills:Activity Collection
Leslie Kanat, Johnson State College
Use a quadruple beam balance to measure the specific gravity of the minerals and rocks that are common in oceanic and continental lithosphere. The results of the calculations are tied to numerous concepts described in previous lectures.

Floods on the Minnesota River - Planning for St. Peter part of Quantitative Skills:Activity Collection
James Welsh, Gustavus Adolphus College
In this lab, students make a flood hazard map for the city of St. Peter, MN.

Reading Topographic Maps and Calculating Map Scale part of Quantitative Skills:Activity Collection
Leslie Kanat, Johnson State College
Use a topographic map to deliniate a watershed, draw a map bar scale, and calculate a map ratio scale.

Population Growth, Ecological Footprints, and Overshoot part of SISL: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.

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

A Monarchy Deposed: The Demise of the Monarch Butterfly part of SISL:2012 Sustainability in Math Workshop:Activities
Daniel Abel
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.

How much energy do you save by doubling insulation? part of SISL:2012 Sustainability in Math Workshop: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.

Modeling: (1) Revenue Neutral Carbon Taxes; (2) Accelerated atmospheric C02 concentrations part of SISL:2012 Sustainability in Math Workshop:Activities
Martin Walter
Design a revenue neutral carbon tax and a plan for implementation; together with a model for what happens if we do not institute such a tax-system.

Should I Unplug? part of SISL:2012 Sustainability in Math Workshop:Activities
Lori Carmack
Short Description goes here: Short DescriptionThis section should be a distillation of the summary above. This description will be displayed in search returns. The optimal length for this description is on the order of 1-2 sentences. Short Description goes here:

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