Many factors influence the success and survival rate of a population of living things. Explore several factors that can determine the survival of a population of sheep in this NetLogo model. Start with a model of unlimited grass available to the sheep and watch what happens to the sheep population! Next try to keep the population under control by removing sheep periodically. Change the birthrate, grass regrowth rate, and the amount of energy rabbits get from the grass to keep a stable population.

    Model with mathematics.

    CCSS.Math.Content.6.SP.B.5a: Common Core State Standards for Mathematics

    Reporting the number of observations.

    CCSS.Math.Content.6.SP.B.5b: Common Core State Standards for Mathematics

    Describing the nature of the attribute under investigation, including how it was measured and its units of measurement.

    CCSS.Math.Content.8.SP.A.1: Common Core State Standards for Mathematics

    Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

    CCSS.Math.Content.8.F.B.5: Common Core State Standards for Mathematics

    Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

    CCSS.Math.Content.HSF-LE.A.3: Common Core State Standards for Mathematics

    Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.

    CCSS.Math.Content.HSF-LE.B.5: Common Core State Standards for Mathematics

    Interpret the parameters in a linear or exponential function in terms of a context.
