Activity Description of "The Natural Selection of Forks and Beans"

Title The Natural Selection of Forks and Beans
Audience Biology
Abstract In this activity, students actively participate as one of three predator species as they attempt to capture as many individuals as possible of four prey species. By maintaining the total number of both prey and predator individuals and by allowing reproduction to occur for successful species, the concept of biological carrying capacity can be simulated. The overall goals of this activity are as follows: �Students will observe how population size can vary from generation to generation in response to changing environmental conditions. �Students will determine which phenotypes (for both predator and prey) are most successful in a given type of environment. �Students will determine how populations of various predator species affect populations of various prey species and visa versa. �Students should prepare graphs comparing population size and generation for both predator and prey populations.
