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.

Earthquake Shaking and Damage part of Quantitative Skills:Activity Collection
Eric Baer, Highline Community College
This student homework and problem set has students quantitatively earthquake hazard, shaking and damage.

Genetic and Empirical Approaches to Classifying Climates part of Quantitative Skills:Activity Collection
Charles Dodd, Shoreline Community College
Students (in groups of 3-4) are given a hypothetical planet and create a genetically based climate regionalization. Students then interpret empirical data of various climate phenomena (precipitation, temperature, evapo-transpiration) from different locations on the planet, and apply these to the Koppen system of climate classification.

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.

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.

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.

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