Amalgamated Industries Think through the consequences associated with the development of a widget plant upstream of the Alma Mater school. While the plant will be good for the region’s economy, will it release widgoxyn—a deadly chemical known to interfere with aquatic food webs—in such quantities that it will irreparably damage the stunningly beautiful Alma Mater Pond? |

Predator Prey Dynamics This simple case facilitates experimentation with the dynamics of a predator-prey system. In the case, the user is asked to experiment with different predator harvests, and observe the effects on both the predator and prey populations over time. |

Easter Island Easter Island has long been viewed as deep in mysteries. Why does the island have so many statues? Why is the landscape so stark and forbidding? And why does the island support so few people? Conduct simulations to explore the effect of different birth rates on the long-term sustainability of the population and its island habitat. |

Plant Succession This model represents the progression that plants go through in a forest ecosystem, from forb to hardwood with each plant type readying soil conditions for the next type in the progression. |
|
Selective Pressure In this model, a rabbit population comes under a natural selective pressure from a fox population. The average speed of the rabbit population increases as a result. You can experiment with the strength of the natural selective force. |
|
Simple Nitrogen Cycle This is a model of a basic nitrogen cycle, bringing the typical textbook diagrams to life by enabling students to play with the parameters which impact the cycle's dynamics. |
