Three-Point Problem by Simultaneous Linear Equations part of Quantitative Skills:Activity Collection

William Frangos, James Madison University

Students are introduced to the use of linear algebra in an intuitive and accessible way, through classroom activity and homework set. The familiar three-point problem is cast in terms of three dimensional analytic geometry, fostering understanding of mathematical models for simple geometric forms.

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.

Assessing the error of linear and planar field data using Fisher statistics part of Quantitative Skills:Activity Collection

Vince Cronin, Baylor University

Instruction on use of Fisher statistics to determine the mean and 95% confidence interval of geological vectors, lines or planes, with examples, problems and an Excel spreadsheet for computation.

Angle of Repose part of Quantitative Skills:Activity Collection

Eric Baer, Highline College

A student activity to determine the angle of repose and what factors determine the angle of repose.

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.

Density of Earth - Using Some Field Data 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 density of the earth and has students do some field experiments to get the data they need to answer the problem.

The Earth's Shells - Density vs. Depth part of Quantitative Skills:Activity Collection

Len Vacher, Dept of Geology, University of South Florida

In this module, students are asked to devise a way of graphically plotting the density variations with depth in the Earth.

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.

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.
