Why Are Bird Beaks So Different?
During our week on birds, we tested out different beaks to figure out the kind of food each beak would eat. To prepare I:
- One beak was tongs and I took 2 Popsicle sticks and inserted a small piece of crinkled up paper between taped it together so the Popsicle sticks are not touching or spring clothespins.
- Used toothpicks or forks to represent beaks that are long and pointy like a hummingbird.
- Used spoons for beaks that can scoop up food, like a pelican.
I taped a circle on the floor and placed pennies, dried kidney beans, rubber bands, buttons and marbles. You can use other small objects.Then I divided the students into groups and explained that each group would collect as much “food” as they could in 5 minutes. Then the fun began! I made a chart to record the outcomes.
After 5 minutes, I recorded how much “food” each kind of beak gathered so they could see if there would be a difference between the beaks. Then we did it two more times with another beak. Attached is a form for the chart that you can enlarge so everyone can see the results.
