Answers
will vary.
 Using graph paper,
plot the pressure of the air as a function of (versus) the altitude.
Students
will make a graph.
 What does this
graph tell you about the relationship between air pressure and the altitude?
The
graph will show that pressure decreases as altitude increases.
 Using graph paper,
plot the temperature of the air as a function of (versus) the altitude.
Students
will make a graph.
 What does this
graph tell you about the relationship between air temperature and the
altitude?
The
graph will show that temperature decreases as altitude increases.

 How does the lift
depend on airspeed?
Lift
increases with airspeed.
 How does the lift
depend on altitude?
Lift
decreases with altitude.
 How does the lift
depend on wing angle?
Lift
increases with wing angle until a certain maximum angle is reached
and stalling occurs.
 How does the lift
depend on wing thickness?
Lift
increases with wing thickness.
 How does the lift
depend on wing camber?
Lift
increases with wing chamber
