In this hands-on activity, students will identify producers and consumers their own state of Wisconsin. Using a set of “Snapshot cards,” they will then create a food chain to show the flow of energy in that system, introduce an ecological force or disturbance (e.g., flooding), and predict how that force would impact energy flow. Lastly, students will construct a more complex model of the flow of energy by depicting multiple relationships in a food web and again make a prediction about the impact of introducing an ecological force.

The Wisconsin Department of Natural Resources uses a variety of tools and techniques to monitor wildlife, and to produce population estimates to better inform management decisions. Population estimates are used to look at long term trends, as well as setting harvest limits during hunting seasons for potentially vulnerable species. There are two count methods for generating population information: sample counts and total counts. In total counts, every individual of an intended geographic area is counted. For sample counts, a smaller fraction of individuals are counted and the data is used to interpolate population information for the entire geographic area. In this activity, you will create a model for these two different count methods and explore the advantages and disadvantages to both approaches.
