What is the Volume of a Debris Flow? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to estimate the volume of volcanic deposits using map, thickness and high-water mark data from the 2005 Panabaj debris flow (Guatemala).

What is the Relationship between Lava Flow Length and Effusion Rate at Mt Etna? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology: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:Partners:Spreadsheets Across the Curriculum:Physical Volcanology: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.

What is the Volume of the 1992 Eruption of Cerro Negro Volcano, Nicaragua? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to calculate the volume a tephra deposit using an exponential-thinning model.

How Do We Estimate Magma Viscosity? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology: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.

How are Flow Conditions in Volcanic Conduits Estimated? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

How Do We Estimate Melt Density? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples
SSAC Physical Volcanology module. Students build spreadsheets to estimate melt density at high temperatures and pressures from the thermodynamic properties of silicates.
