Title: The Beaks of Finches # of the Lab:
Purpose: The purpose of this lab is to be able to work with different tools that will serve to model finch “beaks” and compete with other “finch” species to see which “beak” best adapted for obtaining specific food.
Materials: 1 small plastic dish or cup, 1 large non-breakable dish, 1 tool to serve as a “beak”, large seed, small seed, 2 pairs safety goggles
Procedure: See Lab # The Beaks of Finches given by Mrs. Trimble
Data: See attachments
Results: In this Lab, I learned that you need to be fast and particular with your movements to survive against other “finches.”
Conclusion: The purpose of this lab is to be able to work with different tools that will serve to model finch “beaks” and compete with other “finch” species to see which “beak” best adapted for obtaining specific food. Characteristics of my “beak” that interfered with the feeding success on the original island was that I had to use two hands and the “beak” would lock up. Three traits other than beak characteristics that could contribute to the ability of a finch to compete successfully would be speed, body size, and eye-sight. It’s very unlikely that all of the beaks within a species of finch are exactly alike. Random mutations and new gene combinations resulting from sexual reproduction are the source of beak variations. Three beak variations that could randomly appear and improve my species’ chances of survival when feeding would be a long beak, a scooped beak, and a wider beak. Some “beak” types survive on the new island (with large seeds) when they could not survive on the original island is there was more surface area to latch
