In this activity, students look at data for two populations: cottontail rabbits and gray foxes. Using the data, students calculate the growth of the populations. They then graph the data and observe the differences between exponential and logistic growth. Analysis of the data then occurs. This fits in well with NGSS Biology LS PE 2-1 and 2-2 Population Growth and AP Environmental Science 3.4 Carrying Capacity. A key is provided.

to see state-specific standards (only available in the US).
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales. Examples of mathematical representations include finding the average, determining trends, and using graphical comparisons of multiple sets of data. Assessment is limited to provided data.
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Emphasis is on quantitative analysis and comparison of the relationships among interdependent factors including boundaries, resources, climate, and competition. Examples of mathematical comparisons could include graphs, charts, histograms, and population changes gathered from simulations or historical data sets. Assessment does not include deriving mathematical equations to make comparisons.
