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.

Bubbles in Magmas part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology: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.

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.

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.

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Pedagogy in Action:Partners:Spreadsheets Across the Curriculum:Physical Volcanology:Examples

SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.

Frequency of Large Earthquakes -- Introducing Some Elementary Statistical Descriptors part of Spreadsheets Across the Curriculum:General Collection:Examples

Spreadsheets Across the Curriculum module. Students examine the number of large earthquakes (magnitude 7 and above) per year for 1970-1999 and 1940-1999. QL: descriptors of a frequency distribution.

Shaking Ground - Linking Earthquake Magnitude and Intensity part of Spreadsheets Across the Curriculum:General Collection:Examples

An in-class activity for connecting earthquake magnitude, shaking, and intensity.

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.

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.
