Note: For this lesson you will need the following materials to conduct the lab:

• different tools to act as a beak/ bill of a Finch

• small seeds

• large seeds

• small container (cup)

• larger container (petri dish, plate)

• calculator

• stop-watch

 

Your job in this lab is to determine effects of natural selection. You will represent a Finch and use a tool as a beak to pick up seeds.

Using the image of the following tools answer questions 1 and 2 in the Beaks of Finches Lab.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pick a tool that would represent the beak of your Finch. Complete questions 3 and 4 in the Beaks of Finches Lab.

 

There are three rounds.

Round 1: You will determine if your beak is suitable for the environment. The original island has small seeds. Pick up as many seeds as possible in 30 seconds. How many seeds were you able to pick up?

• If you picked up 13 or more seeds your beak is suitable for this environment. You will continue the next round on the original island with small seeds.

• If you picked up 12 or less seeds then your beak is not suitable for this environment. You must migrate to another island with different seeds in order to survive. This new island will have larger seeds. 

Round 2: You will compete with another specie of Finch. Mark a check to identify which island you inhabit (orginal or new). You and your competitor have 30 seconds to pick up as many seeds as possible. How many seeds were you able to pick up?

• If you picked up 13 or more seeds on the original island then your beak is suitable for this environment. You will continue the last round on the original island with small seeds.

• If you picked up 13 or more seeds on the new island then your beak is suitable for this environment. You will continue the last round on the new islan with large seeds.

• If you picked up 12 or less seeds on the original island then your beak is not suitable for this environment. You must migrate to another island with different seeds in order to survive. This new island will have larger seeds.

• If you picked up 12 or less seeds on the new islan then your beak is not suitable for this environment. Your specie has died!!! Sorry!!! You do not have to complete the third data table.

Round 3: You will compete with all other specie of Finch that survived on the original island or new island. Mark a check to identify which island you inhabit (orginal or new). You and all your competitors have 30 seconds to pick up as many seeds as possible. How many seeds were you able to pick up?

• If you picked up 13 or more seeds on either island (original or new) your beak is suitable for this environment.

• If you picked up 12 or less seeds on either island (original or new) then your beak is not suitable for this environment.
