Scavenger Hunt: Simulating Natural Selection
Read the Fine Print
Rating
0.0 stars
Overview:

Students take on the roles of crab-like predators that have variations in the shape of "claws." Students will then go hunting/scavenging for beans on grass lawns with their feeding appendages, continuing the hunt for three rounds or "generations," with extinction and reproduction occurring between generations. To study evolution by natural selection in this predator population, the class will track the frequency of each appendage type through three generations.
