How Fast Do Materials Weather? part of Starting Point-Teaching Entry Level Geoscience:Interactive Lectures:Examples
Rebecca Teed, Wright State University-Main Campus
A think-pair-share activity in which students calculate weathering rates from tombstone weathering data. -

Two streams, two stories... How Humans Alter Floods and Streams part of Quantitative Skills:Activity Collection
Eric Baer, Highline Community College
An activity/lab where students determine the changes in 100-year flood determinations for 2 streams over time.

Estimating Exchange Rates of Water in Embayments using Simple Budget Equations. part of Quantitative Skills:Activity Collection
Keith Sverdrup, University of Wisconsin-Milwaukee
Simple budgets may be used to estimate the exchange of water in embayments that capitalize on the concept of steady state and conservation principals. This is especially true for bays that experience a significant exchange of freshwater. This exchange of freshwater may reduce the average salt concentration in the bay compared to seawater if it involves addition of freshwater from rivers, R, and/or precipitation, P. Alternatively, it may increase the average salt concentration in the bay compared to seawater if there is relatively little river input and high evaporation, E. Since freshwater input changes the salt concentration in the bay, and salt is a conservative material, it is possible to combine two steady state budgets for a bay, one for salt and one for water, to solve for the magnitude of the water flows that enter and exit the bay mouth. Students will make actual calculations for the inflow and outflow of water to Puget Sound, Washington and the Mediterranean Sea and compare them to actual measured values.

Quantitative Classroom Exercises part of Quantitative Skills:Activity Collection
Steven Schafersman, University of Texas of the Permian Basin, The
The four exercises give students an opportunity to use their knowledge of graphs, algebra, and maps to solve simple geological problems.

Continental Crust Mass Balance Calculation part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
A quantitative skills-intensive exercise using data from the Mineral Mountains, Utah, to calculate mass balance and to address the "space problem" involved with emplacing plutons into the crust.

Flood Frequency and Risk Assessment part of Quantitative Skills:Activity Collection
Carol Ormand, Carleton College
Students calculate recurrence intervals for various degrees of flooding based on historical data. Students then do a risk assessment for the surrounding community.

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.

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.
