Bird Beak Adaptation Lab. Objectives: Students will: ) Comprehend that birds have physically adapted in relation to their type of food supply. ) Deduce what beaks are most efficient for given foods by experimenting with imitation beaks and given food sources. ) Learn the importance of multiple trials. ) Represent their data with a bar graph.

Introduction: How are bird beaks adapted to the foods they eat? In this lab, we will simulate a scramble competition (kind of like in the old kids' game, "Hungry, hungry hippos") between six species of birds in six different environments.
Use evidence to explain how environmental change can lead to strong selective pressure on certain traits. Develop an explanation about how traits can provide a selective advantage under different environmental conditions. Make predictions based on observations and collect quantitative data to test these predictions.

Bird beaks are incredibly diverse. Beaks can be thick and strong to crush nuts, curved like a corkscrew to open snail shells, or even full of combs to make it possible to filter food out of water. These differences arise from the adaptation of animals to their environments. For a run down of various beak types, check out this resource by Zoo Portra...
How did such a wide diversity of beaks evolve? To find out, youll try a new twist on an old favorite: A simulation of bird beak evolution! Comparing bird beak designs through simulated food competition is an old evolution lab standby. Often, evolution lessons model and compare the effectiveness of different adaptations, testing models to determine ...
Over 40 years, the Grants observed and catalogued the leg length and beak width of Galapagos finches and drew some compelling and illuminating conclusions regarding evolutionary success. A severe drought caused a great majority of the finches to die out over a 12-month period and the Grants were able to determine that the surviving finches possesse...
In this activity, success can build on successful variation, allowing you to participate in an exercise on competition, where successful designs are given greater opportunities to adapt and improve. In nature, these changes arise through the confluence of random chance, external conditions, and internal changes such as mutation. As you work, youll ...
How do bird beaks, bills, and rostrums work? Actually, theyre just like our jaw! There is an upper and lower mandible that open and close to capture and consume food. Using the design thinking steps outlined below, you will research, design, and build a beak that you think will be good at capturing and consuming food. Working through this process w...
Why do successful beak designs earn more redesign time? Remember: you are modeling the process of mutation, natural selection, and evolution a process that occurs by chancein the example of the Galapagos finches, the weather events that created the conditions for evolutionary success of a certain beak type were random and unpredictable, and other e...
