Function of Bird Beaks

In science class, we analyzed the differences between birds' beaks.  We examined the shape & size of the beaks to determine why the beaks were shaped a certain way.  As an experiment, students pretended they were birds, using different instruments (beaks), such as tweezers, clothespins, eye droppers, & spoons, to try to pick up different kinds of food. They had to use the different tools to pick up a variety of bird food: fake worms, spaghetti, plastic bugs, water, goldfish in water, & shells.  Students kept track of which tool was the easiest to use for picking up the different kinds of food.  To relate our experiment to our science unit, we'll be discussing how humans have invented tools to mimic the function of a specific bird's beak.  For example, a human invention of a humming bird's beak, would be a straw.  The students have been making wonderful connections!
