    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.

    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.
