Compare and contrast the results between groups. Combine group data to produce a class graph. Display and discuss the graphs. In groups students compare and contrast the effectiveness of different beak types in acquiring food from different sources. Observe students' ability to interpret graphed data.
Teacher leads class discussion of which food type different beaks can successfully collect .
In class discussion determine what food each model represents. Determine which beak characteristics would allow or interfere with the collection of each food type. Students record interpretations, thoughts, and conclusions documented by class data, graphs, and discussions. Formative Assessment Teacher monitors students' ability to synthesize information and to apply the models to an ecosystem. The students should predict what might happen if a drought or some kind of pollution wiped out a particular food source.
