  1. Warmup Define the following: • tributary- a small stream of water that joins another stream 2. stream- fast moving water from a watersource 3. spring- a place where water flows from the ground to the surface 4. wetland- area of land that is sometimes under water or soil contains a lot of water

  3. Bird Beak Adaptation Lab Spencer Johnson 7S Hurd April 8, 2014

  4. Introduction Darwin went to the Galagapos Islands in 1831 and discovered…..blah blah blah…. Using various materials to represent bird beaks, natural selection will be attempted to be modeled in a lab. Hypothesis If a skewer, eyedropper, plastic spoon, and a clothespin, then, a skewer will be best utilized to pick up marshmallows (grubs); the eyedropper, food coloring and water (nectar); the plastic spoon, Styrofoam (waterbugs); and the clothespin, spaghetti (worms).

  5. Procedure Copy from lab Variables Independent: Dependent: Control: Materials Use bullet points and copy from lab Data Insert graphics here and/or tables

  6. Discussion This is the longest part of the lab-you are discussing: • What results you got (basically a paragraph for describing the graphs) • Human error (were there other birds fighting for food and pushing you out of the way • Why were there outliers, if any? • What would make the lab better? • How would you modify the lab to get better results? • How does this have to do with adaptations? Was it a decent lab to do to show what your objective was? • Discuss if your hypothesis was supported. Conclusion Restate the study aims or key questions and summarize your findings using clear, concise statements. Keep this section brief and to the point.
