    Students will investigate how adaptive traits can become non-adaptive traits when the environment changes. Students can change the amount of water to simulate how producers (grasses) affect different consumer (rabbit) populations. Students graph the population changes and write a CER paragraph to explain the observed phenomena.

    A fun predator prey activity that focuses on removal of a limiting factor and how that affects the resilience of the prey population and its environment. Students participate in an activity that models a population of rabbits. Students learn how density-dependent factors affect a population size.

    Lab
    In this population and ecosystem stability lab, students participate in an activity that models predator-prey and how resilient a population can be when limiting factors are introduced or removed. Students will model biotic and abiotic factors and how those factors affect population size. At the end of the experiment, students will make a population growth graph based on the experiment and calculate the growth rate through many generations.

    Students will read and answer questions to distinguish between exponential and logistic population growth, identify carrying capacity, differentiate density-dependent and density-independent limiting factors, apply population models to data sets, and determine carrying capacity from population data. Students will also make predictions based on graphs and interpret graphical data to analyze factors that influence population growth.

    Worksheet
    In this population growth worksheet, students will build their vocabulary about density-dependent limiting factors and density-independent limiting factors that affect population growth and carrying capacity. The focus of this worksheet is for students to provide definitions for the vocabulary words and compare and contrast density-dependent factors and density-independent limiting factors.
