Evolution and Natural Selection
This practical activity explores beak adaptations in bird populations and looks at the way in which variation in beak shape is related to the available food sources within an environment. Using different tools to model different beak shapes children are provided with different kinds of food to pick up. The children with tools best suited for picking up the food provided will end up with the most food. This helps to show that certain beak shapes are more advantageous than others depending on which food is most readily available in their environment. Over time the population of birds will have a higher frequency of these successful beak types.
