Today's class was all about Natural selection. Students spent the period as "ClipBirds" trying to survie on the island of New ClipLand. Clip Birds only sources of food are popcorn kernels, Lima beans, or marbles. The goal of the game is survive and to reproduce. The more food you eat the better chances you have of survival and having offspring. However, the more ClipBirds enter the game, the more competition there will be for the limited resources. There are three types of ClipBirds, Big Beaked, Medium Beaked, and Small Beaked. Every time a ClipBird Reproduces there's a 1/3 chance a mutation occurs, which causes the offspring beak to either be bigger or smaller than their parents. This game highlights a lot of different concepts in ecology and evolution including natural selection, limiting factors, carrying capacity, as well as positive, negative, and neutral mutations. A version of ClipBird Island is attached below:
Bonus Gold Tape Question: Anyone that emails or gives Mr. Powell a written response to this Question by neat Friday, October 20, by the end of class will get a piece of Gold Tape:
Explain how our game ClipBird Island demonstrated all three ecology and evolution concepts of natural selection, limiting factors, and carrying capacity.
