Population Modeling
by Rachel Henry

This lesson delineates a progression from a simple population model to a predator-prey model with an understandable and explicit sequence.

Henry used Vensim simulation software for the class, but the lesson could easily be modified for other simulation software such as Stella or Splash!
CLE xchange Change
Our first newsletter was the summer of 1992 and over the years we have seen dwindling interest in hard-copy. That fact, plus the cost effectiveness of creating a hard copy newsletter, has led us to going to an all digital format.We are still committed to communicating with all of you and sharing the good things that are going on using ST/SD in K-12 education.

Welcome to the new CLE xchange!
