Overview

Lesson 1 Teacher Guide

Purpose

To teach students to understand biological systems using individual- or agent-level behaviors and interactions.

Prerequisite Knowledge

  • Food is a source of energy and building blocks for organisms
  • Food is necessary for animals to survive
  • Plants make their own food while animals and decomposers must consume other organisms
  • Familiarity with food webs and trophic levels

Lesson Description

Students will use their prior knowledge of food webs to examine the specific ecosystem of Isle Royale.  They will make predictions about how the populations of wolves and moose change over time, and attempt to construct a simple agent-based model based on the ecosystem.

Lesson Outline

  1. Introduction
  2. Think about differences between ecosystems broadly
  3. Think about interaction between populations broadly
  4. Think about Isle Royale broadly
  5. Predictions about wolf and moose populations
  6. Brainstorm rules for the model
  7. Revisiting predictions about wolf and moose populations
  8. Think about how and why models are useful
  9. Wrap-up
