Bird Beak Buffet (lesson)
Source: My Science Box
http://www.mysciencebox.org/birdbeak
Students learn about natural selection by becoming birds
foraging for food on an island (area of the schoolyard or
classroom). The prey (beans) vary in their coloration and birds
vary in the type of beak they have. Each season, surviving
predators and prey reproduce. Over several generations, the bird
and bean populations shift. In this way, students model natural
selection and get a good idea of how it works. |
