Predator/Prey/Biomass

Level C: Eat and Be Eaten: Prey as Predator, Predator as Prey

This model explores a moose and wolf population. A predator/prey relationship is present, as with Lesson 4, but now the moose have a food source, creating a more realistic representation of the ecosystem. Students take on the role of wildlife manager and control hunting policies for both predator and prey populations. The default simulation behavior for prey, predators, and biomass is oscillation. Depending on policy decisions, a variety of results occur.

 

Learning goals:

  • Represent and interpret data on a line graph.
  • Compare results for simulation runs.
  • Manage a simulated ecosystem, keeping it healthy.
  • Identify and explain challenges of being a wildlife manager and meeting specific goals.

Student Challenge:

  • Keep the ecosystem healthy while managing related human interests, even in the face of unexpected events such as a drought.

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.
