US Historical Climate: Excel Statistical part of Library:Mathematical and Statistical Models:Examples
Students import US Historical Climate Network mean temperature data into Excel from a station of their choice and use Excel for statistical calculations, graphing, and linear trend estimates.

Vostok Ice Core: Excel (Mac or PC) part of Library:Mathematical and Statistical Models:Examples
Students use Excel to graph and analyze Vostok ice core data (160,000 years of Ice core data from Vostok Station). Data includes ice age, ice depth, carbon dioxide, methane, dust, and deuterium isotope relative abundance.

Mass Balance Model part of 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.

Daisyworld: Interactive On-line PC and Mac part of Library:Mathematical and Statistical Models:Examples
Students use a JAVA interface design by R.M. MacKay to explore the Daisy World model. The JAVA interface comes with a link to a 6-page student activity page in PDF format.

Energy Balance Climate Model: Stella Mac and PC part of 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.

World Population Activity I: Excel part of 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.

Evolution, Natural Selection and Speciation part of Library:Conceptual Models:Examples
In this out of class tutorial, students explore several examples of natural selection and speciation.

Human Demographics part of 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.

World Population Activity II: Excel part of 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.

Trace Gases: Stella II Mac and PC part of 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.

Daisyworld: Stella Mac or PC part of Library:Mathematical and Statistical Models:Examples
After constructing a Stella model of Daisyworld students perform guided experiments to explore the behavior of Daisyworld to changes in model parameters and assumptions.

Wind Surge: Interactive On-line Mac and PC part of 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.

Fishing Game: Stella PC and Mac part of Library:Mathematical and Statistical Models:Examples
As manager in the fish and wildlife service you are charged with making policy regarding the management of a regional fishery.

Salmon Smolt: Stella PC and Mac part of Library:Mathematical and Statistical Models:Examples
The Stella Smolts Migration Model focuses on the spring migration of hatchery smolts to the ocean. It may be used to test the relative merits of barging fish or drawing down the reservoirs to help the smolts reach the ocean.
