Lastly, peripheral adaptations such as webbed feet, bill style and feather features such as coloring, iridescence and plumage are also examined. Students use the jigsaw format of the cooperative learning to learn the stages of the embryonic development of the bird. The five stages are assigned to members of a cooperative learning team. This information is presented in a written description and illustration on two pie shaped pieces. Students return to original teams as the expert to present their data and assemble the pieces of the chicken pie.
All students are responsible for knowing each stage of development.
In the culminating activity, the students create a model of a bird, a bird's egg, and chart it's migration pattern using the information gathered in the previous two weeks of lab and discussion. Overall Value Students will be on a flight soaring through a unit filled to the bill with bird activities. The appeal of the unit is in the hands-on activities which generate a high level of interest and, as a result, greater achievement can be attained by the students.
