This lab can be used either during an ecology unit or an evolution unit when talking about Darwin's finches. Students should know a little bit about ecological niches and adaptations before doing this lab. The download includes instructions, a data sheet, and analysis questions with suggested answers. The lab requires that students model how birds with different beak shapes vary in the types of foods that they eat.
The activity suggests that chopsticks, tweezers, and spoons be used to represent beaks and that marbles, toothpicks, and pennies be used to represent food types. I purchase all materials at Dollar Tree when doing this lab. This lab is easily modified to use whatever materials you have available as well. I have used forks and knives to represent beak types in the past and they have worked just fine.
