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. -

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.

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.

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.

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.

Who Goes There? Estimating Ocean Populations in Chincoteague Bay part of SISL: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.

How Biodiverse is Lake Superior? An exercise in proportions. part of SISL:2012 Sustainability in Math Workshop:Activities

Stephanie Kajpust

Students use critical thinking and algebra to measure and evaluate the biodiversity in Lake Superior.

Salt Marshes: estimation techniques using basic algebra and geometry part of SISL:2012 Sustainability in Math Workshop:Activities

Yelena Meadows; Sharareh Nikbakht

The activity allows for learning about salt marshes ecosystem and practicing of basic math in estimations.

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.
