Introduce a variety of birds in flight pictures. Ask the students to
identify similarities in the various birds you show them.
|
 |
If possible, use a live bird to point out the location of each type of
feather (down, contour, and flight).
|
 |
Ask the students to handle the various bones (chicken, pork, beef, and
bird.) Have them compare their weights to illustrate that birds have
very light-weight bones. Show the students a cross section of the bones
and point out that the birds' bones are less dense because of the air
spaces in them.

 |
Discuss how the respiratory system in birds is designed to provide the
large amount of oxygen needed to produce the energy for flight.
|
 |
Ask the students to list ways on their notebook paper how birds are
adapted for flight. Have them list as many characteristics that they can
of how the bird is built for flight. Discuss these characteristics
together as a class.
|
 |
Pair the students up and ask each team to come up with at least 5
reasons why birds are so important to us.
