Graphing Chemical Data to Identify Fractional Crystallization part of Cutting Edge:Courses:Petrology:Teaching Examples

John Brady, Smith College

Students are given major-element, whole-rock chemical analyses from ten samples of lava from the 1868 eruption of Mauna Loa. They do not know sequence of eruption, only that the lavas came from the same volcano. ...

Variation Diagrams and the Evolution of Thingmuli Lavas, Iceland part of Cutting Edge:Courses:Petrology:Teaching Examples

Jeff Tepper, University of Puget Sound

In this problem set students are provided with an EXCEL spreadsheet containing major element analyses of lavas frm Thingmuli Volcano in Iceland. They are asked to construct variation diagrams (Harker plots) and ...

Demonstration of radioactive decay using pennies part of Quantitative Skills:Activity Collection

Jennifer Wenner, University of Wisconsin-Oshkosh

A demonstration (with full class participation) to illustrate radioactive decay by flipping coins. Shows students visually the concepts of exponential decay, half-life and randomness. Works best in large classes – the more people, the better.

Density of rocks - How large is a ton of rock? part of Quantitative Skills:Activity Collection

Len Vacher, Dept of Geology, University of South Florida

This module addresses the problem of how to determine the size of a ton of rocks of a given composition and invites the student to figure out how to solve the problem.

The Earth's Shells - Thicknesses and Densities part of Quantitative Skills:Activity Collection

Len Vacher, Dept of Geology, University of South Florida

This module explores the combination of densities and shell thicknesses that produce an aggregate density of the Earth of 5.5 g/cm3.

Determining Earthquake Probability and Recurrence from Past Seismic Events part of Quantitative Skills:Activity Collection

Eric Baer, Highline Community College

A homework/classroom activity where students collect historical earthquake information and use it to forecast the probability of larger earthquakes.

Exploring Radiometric Dating with Dice part of Quantitative Skills:Activity Collection

Carla Whittington derived from Baer (1999)
Related Links Radioactive Decay ProbabilityExponential Growth and Decay

An activity in which students use dice to explore radioactive decay and dating and make simple calculations.

What is the fate of CO2 produced by fossil fuel combustion? part of Quantitative Skills:Activity Collection

Paul Quay

A box model is used to simulate the build up of carbon dioxide in the atmosphere during the industrial era and predict the future increase in atmospheric CO2 levels during the next century.

Introduction to Texas Hurricanes part of Quantitative Skills:Activity Collection

Oney Fitzpatrick, Jim Jordan, and Jim Westgate - Lamar University, Beaumont, TX

Students graph data from 20th century hurricanes that affected the state of Texas. Along the way they answer questions that ask them to interpret what they see represented on the graphs.

Density of the Earth - How to Solve It part of Quantitative Skills:Activity Collection

Len Vacher, Dept of Geology, University of South Florida

This module addresses the real problem of determining the density of the Earth and invites the student to figure out how to solve the problem.
