This activity is intended for teaching form and function.
Students are give functions of bird parts such as a beak, feet, wings, eyes, and a tail. After choosing functions that they are interested in, they design their bird on one of their group members.
A debriefing explicitly address that the form of an object is related to function and function frequently relies on form. Form and function can also be comparable to the distinction between observation and inference. Observing a form of an object, organism, and system in nature, scientists infer its function and vice versa.
