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.

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.

What is the Volume of the 1992 Eruption of Cerro Negro Volcano, Nicaragua? part of Pedagogy in Action: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 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 Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Pedagogy in Action: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.

Being P-Waves and S-Waves part of Pedagogy in Action:Library:Role Playing:Examples
Teach students about P-waves and S-waves by having them model them with their own bodies.

Lithospheric Density part of Pedagogy in Action: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.

How are Flow Conditions in Volcanic Conduits Estimated? part of Pedagogy in Action:Library:Teaching with SSAC: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: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.

Slinky and Waves part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
Use a Slinky to show:P and S waves, Wave reflection, and Standing waves in interactive lecture demonstration.

Sun Spot Analysis part of Pedagogy in Action:Library:Teaching with Data:Examples
Introductory students use Excel to graph monthly mean Greenwich sunspot numbers from 1749 to 2004 and perform a spectral analysis of the data using the free software program "Spectra".

Waves Through Earth: Interactive Online Mac and PC part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Students vary the seismic P and S wave velocity through each of four concentric regions of Earth and match "data" for travel times vs. angular distance around Earth's surface from the source to detector.

Mass Balance Model part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Students are introduced to the concept of mass balance, flow rates, and equilibrium using an online interactive water bucket model.

Metric System Conversions: Process Oriented Guided Inquiry Learning (POGIL) activity part of MnSCU Partnership:PKAL-MnSCU Activities
This activity helps student learn to convert within the metric system and begin learning about process skill necessary for working in groups.

Virtual Photoelectric Lab part of Pedagogy in Action:Library:Teaching with Data Simulations:Examples
This is a virtual lab activity on the photoelectric effect based on a Java applet simulation of the experiment.

Introduction to Work and Energy: The Hopper Popper Surprise part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples

Understanding the Motion of a Harmonic Oscillator part of Pedagogy in Action:Library:Interactive Lecture Demonstrations:Examples
This inteactive lecture and series of demonstrations develops the concepts and vocabulary of oscillatory motion as it relates to the motion of a mass on a spring.

Graph Predictions for Position, Velocity and Acceleration part of Pedagogy in Action:Library:Just in Time Teaching:Examples
Graphical Just-in-Time-Teaching questions for use before classes in which students explore position, velocity and acceleration graphs.

Modeling emf, Potential Difference, and Internal Resistance part of Pedagogy in Action:Library:Interactive Lectures:Examples
Through class discussion and think-pair-share questions, this activity helps students come to understand the difference between emf and potential difference in electrical circuits. These concepts are broached within the context of internal resistance of batteries.

Rutherford's Model of the Atom part of Pedagogy in Action:Library:Interactive Lectures:Examples
Students are asked think-pair-share questions to predict the interaction of alpha particles fired toward the nucleus of an atom. An online applet is used to illustrate the interaction and test students' ideas for the causes of the interaction. This activity uses a resource in the comPADRE partner collection.
