Predator and Prey Interactions

Level C: Waves of Change: Predator and Prey Dynamics

The predator/prey model explores a moose and wolf population living on a small island. Students can change various components of a predator/prey model, including birth factor, lifespan, and habitat area. The default simulation behavior is oscillation of both prey and predator populations, in which the state of each population impacts the state of the other over time.

 

Learning goals:

  • Represent and interpret data on a line graph.
  • Compare results for simulation runs.
  • Explain the concept of density with regards to population dynamics.
  • Represent a food source for the moose on the simulation map or loop diagram.

Student Challenge:

  • Given an analysis of what is causing the two populations to oscillate, create conditions which best stabilize (minimize the oscillations of) the ecosystem on the island.

Curricular Connections:

  • Science: Populations, ecosystems, scientific method
  • Math: Vary assumptions, explore consequences, and
    compare predictions with data.
  • Reading: Analyze a complex set of ideas or sequence
    of events and explain how specific individuals, ideas, or
    events interact and develop over the course of the text.
