Question Does the shape of a bird’s beak affect how much food it can obtain?

Research An adaptation is a characteristic that helps a plant or animal survive in its environment. Bird beaks have adapted for many things such as eating, defense, feeding young, gathering nesting materials, building nests, preening, scratching, courting and attacking. The size and shape a beak is specific for the type of food the bird gathers. For example, cardinals have heavy thick bills used to crack seeds, and humming-birds have thin bills to sip nectar.

Hypothesis If _____________________________________, then __________________________________. If the shape of a bird’s beak changes, then the amount of food it can obtain will change. If the shape of a bird’s beak changes, then the amount of food it can obtain will not change. What is your independent variable? What is your dependent variable?

Experiment Materials: 1 pair of scissors 1 clothespin 1 spoon 1 plate of beans 1 cup 1 timer

Experiment Procedure: 1.Place the plate of beans on a plate on a flat surface. 2.Set the timer for 20 seconds. 3.Start the timer and use the scissors to pick up one bean at a time, placing each one into the cup. 4.Continue picking up the beans until the timer stops. 5.Record the number of beans that are in the cup. 6.Using the scissors, repeat steps 2 to 5 two more times. 7.Pick up the clothespin and repeat steps 2 to 6. 8.Pick up the spoon and repeat steps 2 to 6.

Conclusion – Hypothesis reflection Was your hypothesis correct or incorrect? Why? – Areas of improvement How could you improve this experiment in the future? – Application section What did the experiment teach you? How can you use this information in real life?

Question What adaptation does a bird have to obtain food? Why?
