PPT-Predator – Prey Lab Experiment

Our simulation will consist of a game in which predators students with different size mouths forceps will compete to capture prey beans which vary in color There are four predator phenotypes different size and shaped forceps and four prey phenotypes differing in color and size whitelarge brownmedium black medium amp tansmall.
