  1. State Lab: The Beaks of Finches (page 117) 1. You will turn in the answer packet (pages 125 to 130) 2. Put desks in groups of 2 3. Count off by letters (A to L) 4. Sit next to your partner

  2. A. B. C. E. D. F. G. H. I. J. K. L. 4. Pick up your beak.

  3. A. B. C. E. D. F. G. H. I. J. K. L. 5. Do questions 1 through 4 of lab

  4. State Lab: The Beaks of Finches (page 117) 6. ONE partner pick up a large dish with seeds (environment) and a small dish (your birds gastrointestinal (GI) tract = digestive system). 7. Only ONE seed can be eaten at a time!! 8. Don’t count seeds that hit the table 9. Practice now

  5. State Lab: The Beaks of Finches (page 117) “Round One: Feeding with no competition” You are all on the large island of Isabela in the Galapagos.

  6. State Lab: The Beaks of Finches (page 117) “Round One: Feeding with no competition” - 4 trials (2 per person) - transfer as many seeds as possible in 30 seconds - average the four trials - must collect 13 seeds (average) per trial to survive on this island.

  7. State Lab: The Beaks of Finches (page 117) “Round One: Feeding with no competition” 1. If you collected fewer than 13, you must “migrate” to the island of Santa Cruz 2. Santa Cruz has larger seeds. 3. One person from each migrating group please exchange seeds

  8. State Lab: The Beaks of Finches Class Results

  9. State Lab: The Beaks of Finches (page 117) “Round two: Competition” - you will now compete on your island - 4 trials, 30 seconds each - feed from the same dish - 30 seeds only on the island - if you get less than 13, you are extinct!

  10. State Lab: The Beaks of Finches Class Results

  11. State Lab: The Beaks of Finches (page 117) “Round three: Increased Competition” - You will now compete on your island with ALL remaining members of your population. - 4 trials, 30 seconds each - ALL finches feed from the same dish on each island (10 x # groups of seeds only). - if you get less than 13, you are extinct!
