Using a Mass Balance Model to Understand Carbon Dioxide and its Connection to Global Warming part of Quantitative Skills:Activity Collection

Bob Mackay, Clark College

Students explore the increase in atmospheric carbon dioxide over the past 40 years with an interactive on-line model.

Investigation: When will there no longer be glaciers in Glacier National Park? part of Quantitative Skills:Activity Collection

An Investigation Question activity developed by Carol Ormand, Wittenberg University.

Students use historical data on the extent of the Grinnell Glacier in Glacier National Park to estimate when the glacier will melt completely.

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.

Is There a Trend in Hurricane Number or Intensity? part of Cutting Edge:Topics:Hurricanes-Climate Change Connection:Activities

Todd Ellis, SUNY College at Oneonta

This lab guides students through an examination of the hurricane record to determine if there is a trend in hurricane intensity over the past 40 years and introduces some issues related to statistics and ...

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.

Back-of-the-Envelope Calculations: Rate of Lava Flow part of Quantitative Skills:Activity Collection

Barb Tewksbury, Hamilton College

Question In 1983, an eruption began at Kilauea Volcano in Hawaii that has proved to be the largest and longest-lived eruption since records began in 1823. Lava has poured out of the volcano at an average rate of ...

Back-of-the-Envelope Calculations: Weight of Gold part of Quantitative Skills:Activity Collection

Barb Tewksbury, Hamilton College

Question Let's suppose that you have a shoe box full of water (the box is waterproof, of course). The shoe box weighs about 9 kg (19.8 pounds). Suppose you emptied the box and filled it completely with rock ...

Understanding Radioactivity in Geology: The Basics of Decay part of Quantitative Skills:Activity Collection

Christina Stringerâ€”University of South Florida, Tampa FL 33620
This activity was developed for Spreadsheets Across the Curriculum . National Science Foundation, DUE 0442629.

PowerPoint module leading students through creation and manipulation of spreadsheet to forward model an example of exponential decayâ€”the number of remaining unpopped kernels of popcorn in a bag of popping popcorn.

The Modern Atmospheric CO2 Record part of Starting Point-Teaching Entry Level Geoscience:Teaching with Data:Examples

Bob Mackay, Clark College

Students compare carbon dioxide (CO2) data from Mauna Loa Observatory, Barrow (Alaska), and the South Pole over the past 40 years to help them better understand what controls atmospheric CO2. -

Carbon Dioxide Exercise part of Starting Point-Teaching Entry Level Geoscience:Interactive Lectures:Examples

Rebecca Teed, Wright State University-Main Campus

Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. -
