Hypothesis: Airfoil shaped blades fly higher than
flat blades.

Principle: Wind turbine blades are airfoil shaped because
it takes less power to turn an airfoil shaped blade than it
does to turn a flat blade.

Experiment: Place the airfoil model to a safe place where
it can can be turned on and ran without interference.

1. Measure how high the airfoil shaped wing flies.
2. Measure how high the flat wing flies.

Conclusions: Have students do calculations and discuss
what they learned.
