4. Pre-Investigation 1.Examine the different tools (“Beaks”) and seeds provided. Predict which “beak” will be the most successful at picking up small seeds. Give the reason for your choice. 2.Predict which ‘beak” will be the least successful at picking up seeds. Give the reasons for your choice. 3.From this point on you, you and your partner will model a finch feeding. The tool you were assigned will be your “beak”. Describe what characteristics it has or that make it beneficial or non-beneficial for picking up small seeds. 4.In the space below draw an outline of your “beak”. 5. Both you and your partner practice using your “beak to transfer the small seeds 1 at a time from Island (plate) To mouth (cup).

5. Round One: Feeding with no Competition Original Island-Small Seeds # seeds collected Partner #1Trial #1 Trial #2 Partner #2Trial #1 Trial #2 Partner# 1&2Average Partner average fewer than 13 seeds/30 sec. move to New- Large Seed Island for Round Two: Feeding with Competition. Partner average greater than 13 seeds/30 sec. stay on Original- Small Seed Island for Round Two: Feeding with Competition.

6. Round Two: Feeding with Competition Original Island-Small Seeds # seeds collected Partner #1Trial #1 Trial #2 Partner #2Trial #1 Trial #2 Partner# 1&2Average Partner average fewer than 13 seeds/30 sec. you are now extinct. Partner average greater than 13 seeds/30 sec. move onto Round Three: Feeding with Increased Competition. New Island-Large Seeds

7. Round Three: Feeding with Increased Competition Original Island-Small Seeds # seeds collected Partner #1Trial #1 Trial #2 Partner #2Trial #1 Trial #2 Partner# 1&2Average New Island-Large Seeds Fill in Data Table: Class Results Complete Analysis Questions

8. Beaks That WereNumber of Beak Types Types of Beaks (Name of Tool) Present at the beginning of activity Successful at feeding in Round One: Original Island – Small Seeds. Not Successful in Round One: Had to move to New Island - Large Seeds Successful at feeding in Round Two: Original Island – Small Seeds Successful at feeding in Round Two: New Island – Large Seeds Data Table: Class Results

9. Not Successful in Round Two on either Island – became extinct. Successful at feeding in Round Three: Original Island – Small Seeds. Successful at feeding in Round Three: New Island – Large Seeds Not Successful in Round Three on either Island– became extinct Data Table: Class Results Continued
