Beaks as Tools: Selective Advantage in Changing Environments

This Beaks as Tools: Selective Advantage in Changing Environments activity & project also includes:

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available. They learn the importance of having the right tool for the right type of food. Data collection, discussion, and analysis connect the concepts to natural selection.
