Porosity and Permeability of Magmas part of 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.

Glacier (?) National Park part of Library:Teaching with SSAC:Examples

Carbon Sequestration in Campus Trees part of 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.

Spreadsheet Warm Up for SSAC Geology of National Parks Modules, 2: Elementary Spreadsheet Manipulations and Graphing Tasks part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum/Geology of National Parks module. The second of two tutorials. Focuses on modifying spreadsheets (e.g., copy/paste, insert, sort) and creating and modifying graphs.

Lithospheric Density part of Library:Teaching with SSAC:Examples
Students learn about the weighted mean by building spreadsheets that apply this concept to the average density of the oceanic lithosphere.

Exercise to Calculate River Discharge part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module. Students use field data from rivers to understand how river discharge is calculated.

Just How Faithful is Old Faithful? Finding Order in Random Behavior part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum/Geology of National Parks Collection. Students create a histogram to examine the time between geyser eruptions of Old Faithful, Yellowstone National Park.

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Library:Teaching with SSAC: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.

What is the Relationship between Lava Flow Length and Effusion Rate at Mt Etna? part of 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.

What is the Volume of the 1992 Eruption of Cerro Negro Volcano, Nicaragua? part of Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to calculate the volume a tephra deposit using an exponential-thinning model.

Bubbles in Magmas part of 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 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.

How Do We Estimate Melt Density? part of Library:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build spreadsheets to estimate melt density at high temperatures and pressures from the thermodynamic properties of silicates.

Shaking Ground - Linking Earthquake Magnitude and Intensity part of Library:Teaching with SSAC:Examples
An in-class activity for connecting earthquake magnitude, shaking, and intensity.

From Isotopes to Temperature: Working With A Temperature Equation part of 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.

Global Climate: Estimating How Much Sea Level Changes When Continental Ice Sheets Form part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module. Students build spreadsheets to estimate how far sea level drops during a continental glaciation.

Comparing Stream Discharge in Two Watersheds in Glacier National Park part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students study how discharge per unit area varies with elevation in the high country of Glacier National Park from USGS hydrograph data from Swiftcurrent Creek and its tributary Grinnell Creek..

A Percentage Stroll through Norris Geyser Basin, Yellowstone National Park part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate percentages and percent differences to compare various measures of fumaroles, mud pots, hot springs and geysers in this introduction to hydrothermal features at Yellowstone NP.

Shifting Sands: Quantifying Shoreline and Dune Migration at Indiana Dunes National Lakeshore part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students use weighted averages and data from air photos from 1939 to 2005 to calculate the rate of retreat of the shoreline and the advance of the front of dunes along the shoreline.

Dunes, Boxcars, and Ball Jars: Mining the Great Lakes Shores part of Library:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module/Geology of National Parks course. Students estimate the volume of sand in Hoosier Slide, a large dome-shaped dune quarried away in the 1920s from what is now Indiana Dunes National Lakeshore. They also estimate the number of boxcars to carry the sand, and the number of Ball jars produced from it.
