Ecosystem Simulations and Chaos on the Graphing Calculator
Sinn, Robb
Mathematics Teacher, v101 n3 p167-175 Oct 2007
An eighth grade algebra class used graphing calculators to simulate ecosystems. One simulation introduced mathematical chaos. The activities exposed the students to nonlinear patterns and modeling. The rate-of-change investigations related the ideas of intercept and slope to the changing equilibrium. The chaotic model intrigued them and was useful in two ways. First, they understood the viability point of an ecosystem. Second, they enjoyed experiencing the chaos, searching for periodic orbits, and learning that crazy things can happen in mathematics. Three classroom-ready worksheets are included. (Contains 4 figures, 2 tables, and 7 resources.)
