Set up six stations to represent different types of food that birds might eat, as follows:
The pliers, the tweezers, the spoon, and the drinking straw are going to represent different types of bird beaks. The six stations you have set up will represent different types of food that different birds eat. Using your beak tools, decide which tool is best suited for each type of food.
Answer the following questions in an essay format (250-300 words)
Describe how the development of a special beak shape could affect a bird species’ survival. How might beak shapes change over time if the usual food source changed? For example, if small insects began hiding deeper within a tree or if sunflower seeds developed harder shells? Describe how natural selection and evolution are demonstrated by this activity.
