Mass Balance Model

Students are introduced to the concept of mass balance, flow rates, and equilibrium using an online interactive water bucket model.

Human Demographics

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

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.

Daisyworld: Interactive On-line PC and Mac

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.

Daisyworld: Stella Mac or PC

After constructing a Stella model of Daisyworld students perform guided experiments to explore the behavior of Daisyworld to changes in model parameters and assumptions.

Fishing Game: Stella PC and Mac

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

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.
