SCIENCE CONCEPT:
- As airspeed increases, pressure decreases creating upward lift.
STUDENT OBJECTIVE:
- Student will be introduced to the principle of lift.
OVERVIEW:
- Student will perform a simple experiment using a ping-pong ball
and a funnel to gain an introduction to the principle of lift.
TEACHER TEXT:
- The feathers have a stiff, straight part running through them
called a shaft. On both sides of the shaft are vanes composed of
barbs which are held together by barbules. The bird's wings with
each of its feathers are shaped much like an aircraft's
wing--curved on top and flatter underneath. This allows both wings
to achieve lift in the same way.
