Radioactive Decay and Geochronology part of Quantitative Skills:Activity Collection

Kirsten Menking, Vassar College

Students create a STELLA model of the radioactive decay process.

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.

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. -

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.

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 ...

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

Roping Geologic Time part of Rates and Time:GSA Activity Posters

Randall Richardson, The University of Arizona

After having talked about the geologic time scale, I ask for two volunteers from the class to hold a rope that is 50 feet long. I say that one end is the beginning of the Earth (4.6 billion years ago), and the other is today. I then give out 16 clothes pins and ask various students to put a cloths pin on the 'time line' at various 'geologic events'. Throughout the activity I have a quiz going on where the students calculate percentages of Earth History for major geologic events, and compare it to their own ages. On their time scale, the dinosaurs died only about two 'months' ago! The exercise is very effective at letting them get a sense of how long geologic time is, and how 'recently' some major geologic events happened when you consider a time scale that is the age of the earth.

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. -

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.
