Abstract

The simulation that we created in Agent Sheets entitled Don’t Break the Chain is a multi-faceted tool for any classroom. It covers a variety of topics in Biology including ecosystems, food chains, invasive species, habitat destruction, and population growth. Students can better understand how living things in nature are connected and how human’s actions can affect the environment.

One of our goals was to provide students something to look at that enabled them to see how different species rely on each other for survival. We also wanted students to be able to manipulate different factors that could change the balance in the system. By having the students introduce variables related to human impact they will better understand topics such as extinction, endangered species and endangered species.

Don’t Break the Chain could be used in a classroom anywhere from a demonstration to a virtual lab. Teachers can actively engage students because it allows them the opportunity to make predictions, test their predictions, and think critically. It can be used in tandem with an online invasive species simulation to extend on the topic.

There are several New York State Standards that our simulation covers and they are the following:

  • 1.1d The interdependence of organisms in an established ecosystem often results in approximate stability over hundreds and thousands of years. For example, as one population increases, it is held in check by one or more environmental factors or another species.
  • 1.1f Every population is linked, directly or indirectly, with many others in an ecosystem. Disruptions in the numbers and types of species and environmental changes can upset ecosystem stability.
  • 3.1a Interpretation of data leads to development of additional hypotheses, the formulation of generalizations, or explanations of natural phenomena.
  • 1.1c In all environments, organisms compete for vital resources. The linked and changing interactions of populations and the environment compose the total ecosystem.
  • 1.1e Ecosystems, like many other complex systems, tend to show cyclic changes around a state of approximate equilibrium.
