Energy Balance Climate Model: Stella Mac and PC part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Students explore a Global Energy Balance Climate Model Using Stella II. Response of surface temperature to variations in solar input, atmospheric and surface albedo, atmospheric water vapor and carbon dioxide, volcanic eruptions, and mixed layer ocean depth. Climate feedbacks such as water vapor or ice-albedo can be turned on or off.

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.

World Population Activity II: Excel part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
(Activity 2 of 2)In this intermediate Excel tutorial students import UNEP World population data/projections, graph this data, and then compare it to the mathematical model of logistic growth.

World Population Activity I: Excel part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
(Activity 1 of 2) This activity is primarily intended as an introductory tutorial on using Excel. Students use Excel to explore population dynamics using the Logistic equation for (S-shaped) population growth.

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.

Wind Surge: Interactive On-line Mac and PC part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Wind surge is a JAVA based applet for exploring how water level on the windward and leeward side of a basin depends on wind speed, basin length, water depth, and boundary type.

Sea Floor Spreading II part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
Students import ocean bathymetry data from text files, they then use Excel to graph these observations along with model prediction to assess the model's ability to simulated the observed topographic features of the North Atlantic.

Trace Gases: Stella II Mac and PC part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
This Stella model allows students to learn about chemical mass balance in the atmosphere and apply this to atmospheric chlorofluorocarbon and carbon dioxide concentrations.

Sea Floor Spreading I part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this introductory Excel tutorial (Activity I) students use Excel to explore the geodynamics model equation for ocean depth around a sea-floor spreading center. For students with no prior Excel experience.

Human Demographics part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this biology simulation students explore factors that change human population growth including age at which women begin to bear children, fertility rate and death rate.

Genetic Drift part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
In this biology simulation, students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. Students run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results.

Conics and Reflection part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
This is a discovery bases lesson on the reflective properties of the conics: parabolas, ellipses, and hyperbolas.

Chemical Equilibrium Misconceptions part of Pedagogy in Action:Library:Mathematical and Statistical Models:Examples
This STELLA modeling and writing assignment helps students confront and replace common misconceptions about chemical equilibrium.
