What is the Relationship between Lava Flow Length and Effusion Rate at Mt Etna? part of Pedagogy in Action:Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students use Excel to determine a log-log relationship for flow length vs effusion rate and compare it with a theoretical expression for the maximum flow length.

Porosity and Permeability of Magmas part of Pedagogy in Action:Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

Bubbles in Magmas part of Pedagogy in Action:Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

How Do We Estimate Magma Viscosity? part of Pedagogy in Action:Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

Carbon Sequestration in Campus Trees part of Pedagogy in Action:Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module. Students use allometric relationships to calculate tree mass from trunk diameter in a stand of trees in the Pacific Northwest.

From Isotopes to Temperature: Working With A Temperature Equation part of Pedagogy in Action:Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module. Students build a spreadsheet to examine from a dataset the relation between oxygen isotopes in corals and the temperature of surrounding seawater.
