SCIENCE CONCEPT:
- Lift occurs when the pressure on the upper surface on an object (wing) is less than the
pressure on the lower surface.
STUDENT OBJECTIVE:
- The student will demonstrate the effect of faster moving air.
OVERVIEW:
- The student will experiment with a candle and card to demonstrate the effect of faster
moving air.
TEACHER TEXT:
- With the increase in speed on top, the pressure exerted
decreases. This change makes the pressure pushing up from under
the wing greater than the pressure pushing down
on the top of the wing, so the wing moves up naturally.
