4. Evolution: Bean Lab
The purpose of this lab is to understand evolution by simulating the competition of different birds for a common food source.
Each student will simulate different beak shapes (fingers, spoon, knife, and fork).
In Charles Darwin’s On the Origin of Species, he stated that individuals best suited for a specific habitat will survive and pass their favorite traits on to their offspring.
In this lab, students that obtain the most food will pass their beak shape to the next generation, while the students with the least amount of food will go extinct.

5. Problem: Which bird beak is the most successful at catching prey in a certain environment? Hypothesis: Write a hypothesis predicting which type of beak (fingers, spoon, knife, or fork) will be the most successful in collecting food. If the beak type is a _____________, then __________________________.

6. Procedure:
Students will be divided into groups of 4. Each student represents a different bird species with different shaped beaks. For the first trial, one student will represent each beak shape: fork, spoon, knife, and fingers.
Spread the beans provided in the box in front of you. The beans represent seeds which are the birds’ food.
For thirty seconds, each bird removes beans, one at a time, from the paper towel using only their beak (fingers, fork, spoon, or knife). A couple things that must happen:
The box must remain still in the middle of the table
The food must be picked up and placed in your stomach (cup)
The stomach (cup) must remain on the table
You cannot steal from the competition
After 30 seconds, count the number of beans each species has eaten. Record the data in the data table.
The bird with the least amount of beans goes extinct. That bird must change its beak shape to the one who ate the most beans.
Repeat this process two more times.

9. Prepare a line graph. Use a different color line for each species and provide a key.
-Graph Title: “Food collecting ability of four species of bean eaters.”
-Y axis: # of beans collected
-X axis: Trial # (represents the generations)
-Lines: The graph will have 4 lines, one for each species in different colors.
-Conclusion: Based on the results,
describe the change in the populations over 3 generations. Explain the relationship between ability to gather food and the ability to survive.
