Have a discussion together about the material in the Teacher Text.
|
|
Show the pictures of the wings of airplanes and birds. Discuss the
various parts.
|
|
Hand out poster boards to each student. Ask them to list in two
columns the similar parts on the bird wing and airplane wing that
approximate the same function in flight.
|
|
Put the model balsa wood airplanes together and proceed outside.
Take turns "flying" the planes. For those students who cannot bring in a
model airplane have them make paper airplanes with paper, scissors, and
tape (they can include slats and flaps on the paper airplanes). Ask the
students to make observations of the flight of the planes.

|
|
Take turns watching birds fly through the binoculars. Ask the
students to make observations of the flight of the birds.
|
|
Return to the classroom and discuss the observations of the students
of the flight abilities of the birds and the airplanes and how flaps and
slats improve the quality of lift.
