Flight has to have three things to fly. Wings that create lift, it must create it’s own thrust and has to be controlled.

Lift and thrust make it possible for an object or animal to fly. Weight and drag push against the object or animals ability to fly. Lift is an upward pull and drag makes it go backwards. Thrust is what makes it go forwards.

Birds are like planes because of their wings and shape. They both use the four forces which are drag, weight, lift and thrust. Birds have hollow bones so they are light to fly. Birds have special feathers called contour feathers. It is a special feather to help them fly. Birds have air sacks which are what helps the bird to breathe when they fly. Birds wings are the shape of an airfoil.

Planes are like birds. To fly planes need to use the four forces. They also have airfoil shaped wings. Planes have flaps. The back flap is called a Rudder that is what makes it turn. Then you have the Elevators which make it go up and down. Then you have the Ailerons which make it tilt.

Planes and Birds have a lot of the same features, as well as a lot of different features. Now you should know a lot about planes and birds. Insects are different but they fly. Next step butterflies… = =
