Why do different bird species have such different beak shapes? Each beak is shaped to match what that bird eats. You visit a bird facility and pick five species with different beak shapes. Then you photograph or draw each one. Next you visit a hardware store and find tools that match each beak shape. A long thin beak might match a probe. A short heavy beak might match a nutcracker. You use each tool's function to guess what the bird eats. Then you research the actual diet online and check your predictions.
