Bubbles in Magmas
Module by Chuck Connor, University of South Florida, Tampa. This cover page by Ali Furmall, USF, now at U. Oregon.
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?
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?
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?
SSAC Physical Volcanology module. Students build spreadsheets to estimate melt density at high temperatures and pressures from the thermodynamic properties of silicates.
Geologic Time Calculations
Francisco San Juan, Elizabeth City State University
Radiometric age determination using parent/daughter composition and a radiometric decay curve.
The Science of Sugaring
Understanding Acid-Base Titrations using Microsoft Excel
This exercise uses a PowerPoint learning module to help students understand the relationship between pH and hydronium concentration in acid-base titrations.
Something is Askew at Mammoth Cave National Park
Module by: Amie O. West, University of South Florida Cover Page by: Amie O. West, University of South Florida
Spreadsheets Across the Curriculum/Geology of National Parks module. Students use the geometric mean and multiplicative standard deviation to examine the right-skewed distribution of nutrient concentrations in water-quality data at Mammoth Cave National Park.
Calibrating a Pipettor
Spreadsheets Across the Curriculum activity. In advance of an actual lab activity, students virtually simulate the calibration of a laboratory micropipettor. QL: Accuracy and precision.
Chemical Equilibrium -- What Are the Characteristics of Equilibrium Reactions?
Spreadsheets Across Curriculum module. Students build spreadsheets to compare the time course of a reaction that goes to completion to that of an equilibrium reaction.
