Mrs.
Fent's and Mrs. Schulte's sixth-grade classes at West Middle School conducted a lab on bird beak
adaptations.
Through
this lab the students gained a better understanding of how the shape and size
of a bird's beak determines the size and shape of their food. The size and
shape of the bird's beak also factored in on how birds used their beak to
gather food. Depending on the shape and size of the bird's beak, some birds
pierced their food, while others scooped or merely pinched their food.
In
the second trial of this lab, some food sources were removed and in other
instances the bird's beak was injured in some way. During the second trial,
students learned that if the bird's food was removed, the bird would die or
need to migrate to find a new food source. Among the birds with a
"handicapped beak" the students saw that these birds also needed to
find other food sources for survival.
This
lesson showed sixth grade students the importance of adapting to new
environmental situations. It also demonstrated how physical adaptations of bird
beaks directly resulted in determining the particular food sources of
individual bird species.
