It is not unusual to use bird beaks as an example of adaptations for preteen biologists. In this particular version, there is a competitive aspect. Learners first all gather the same food with the same style of beak as a baseline comparison. Then, a variety of food is made available, but individuals all have a different beak. This is repeated with everyone having a chance to experience each beak style, which actually draws the lesson out unnecessarily. Finally, different situations are also introduced, wiping out particular food types.
