This is a lab exercise that is meant to engage students in the process of understanding population dynamics and the rate of growth within populations based on the interaction of predators and their prey. In this lab, the student simulates the interactions between a predator population of lynx and a prey population of rabbits within a self-contained meadow space. During the lab, students will model the impact of survival, death rates and birth rates on two distinct but interrelated populations over the course of 16 generations. After collecting the data, the student graphs the data and then extends the graph to predict the populations for several more generations. Students will also work to predict what occurs if predator or prey populations encounter disease that eliminates one or the other from the interaction.
