Then perform Procedure 1 following the modified instructions as seen below Natural Selection for Bird Beak Shapes 1. Write a hypothesis regarding beak shape and the ability to gather food. Darwin proposed that natural selection had shaped the beaks of different bird population as they became adapted to eat different foods. 2. Identify the ...

Hypothesis: If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time. Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Mar 26, 2009 · What would be a creative title for a lab report about bird beaks and natural selection? Answer ... selection on bird beaks? it really depends on what the lab was ...

Bird Beaks (GRADE 4, LIFE SCIENCE) page 5 LAKE SCIENCE COLLABORATIVE Teacher Does Student Does Concept EXPLORE #1: Distribute “Natural Bird Beaks and Food Sources” handout. Tell students that the beak shapes are illustrated in the left column and the corresponding food sources are in the right column. Have students use “Accountable Period_____ DARWIN’S FINCH BEAK LAB (1 point) Objective: This exercise examines the competition among bird species for food in the same ecosystem. You will act as a representative of different species of birds with different beaks (spoon, tweezers, scissors, spring clothespin, toothpick). and shape of a bird’s beak determine the kinds of food the bird can eat and the kinds it can’t. A slight difference might give one bird an advantage over another in surviving and reproducing, and the advantaged offspring, in turn, would be more likely than others to survive and reproduce. Darwin called this process natural selection. Others

Apr 01, 2013 · The bird with the most food consumed is declared “thriving” and is rewarded with two children with the same beak. The remaining two birds survive and have one child each with the same beak. The new generation will consist of two birds (beaks/teams) for the bird eating the most food and declared as thriving,... 2. How does natural selection control the genetic diversity found in populations? 3. Using your knowledge of natural selection, explain how extinction occurs. Extension Activities: 1. Read The Beak of the Finch by Jonathan Weiner. Write a detailed report that illustrates the similarities between your simulation of natural selection in a bird Mar 26, 2009 · What would be a creative title for a lab report about bird beaks and natural selection? Answer ... selection on bird beaks? it really depends on what the lab was ...

Bird Beaks Lesson from Science NetLinks. For examples of scholarly studies into bird beaks and their variations in shape and size, refer to Simple Math Explains Dramatic Beak Shape Variation in Darwin’s Finches from Science Daily and Gravity-Defying Bird Beak Mystery Solved: Shorebirds Benefit From Surface Tension from Science Daily.

Traits other than beak type might affect natural selection. It could take many generations to observe adaptions to a population. The environment may be complex and hard to study. Changes in the environment may occur faster or slower than changes to the birds The birds may be interdependent with other organisms that may change, too. A fun bird beak lab -- using spoons, tweezers, clothespins and coffee stirrers as your beaks -- and water, marshmallows, sunflower seeds, gummy worms and fruity cheerios. First make a prediction for each beak and each food to see if it will be a good combination in order for that bird to eat. Once... Birds, Beaks, and Natural Selection—A Simulation In this simulation, students gather data to see how beak mutations can influence natural selection. Objective Students learn about the role of mutations in natural selection and evolution. Procedures 1. The three to four students in your group represent individual wading birds within a Period_____ DARWIN’S FINCH BEAK LAB (1 point) Objective: This exercise examines the competition among bird species for food in the same ecosystem. You will act as a representative of different species of birds with different beaks (spoon, tweezers, scissors, spring clothespin, toothpick).

The 1 bird that ate the most will reproduce and have a similar-beaked baby. The 1 bird that ate the least will die and get reincarnated as that bird baby of the bird who got the most beans. Data Table: Type of Beak Number of Beans “Eaten” By Each Type of Bird Year 1 Year 2 Year 3 Year 4 Year 5 Toothpicks Spoons The size and shape of a beak is specific for the type of food the bird gathers. For example, cardinals have heavy thick bills used to crack seeds, and humming-birds have thin bills to sip nectar. Other uses include: sifting, sucking, cracking, crushing, spearing, tearing, picking, and probing. Pre-Lab Questions. 1. Data Entry: Using a table like the one below, record the S pecies (type of beak), E nvironment (type of food), and both the number and percentage of the total food items eaten by each type of bird. Create a bar graph of percent food eaten with 36 bars (a bar for each of the six species in environment 1, env. 2, etc.) using a program like Excel.

Natural Selection Lab This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait.
