Let’s Get Silly!


Bernoulli’s Principle


Paper Airplanes – YEAH!• Excellent demo or activity to activate

students brains• Use models online• Build your own paper airplane• Can be used later


What Is an Airfoil?


Spinning Fan Blades


Making an Airfoil• Use poster board, cardstock paper, or

manila folders• Cardboard is also easy to use.• Fold and tape• Attach strings


Step 1

Lay cardboard flat and measure 15 mm from one end and 24 mm from the

other end and make a line on each.


Step 2

Fold in halfMake a camber top by lining the edge of the paper to the

24 mm side.


Step 3

Make a hole in the bottom and top, through the widest

part.Attach string with tape.


Step 4

Attach wire to base.Add bead to top.

Secure loosely at 70°.


Step 5

Observe and then set to 40°.Turn plane upside-down and

repeat same procedures.


Substitutions

Foam boardCraft wire

Play dough2 String hooks


Paper Airplanes Again• Connect to real work – Wind tunnel

testing• Dip deeper into student though

processes• Improving on an experimental design


Goal?• I want to know the maximum angle of

attack for my airplane before it stalls.• I want to make an airplane that…– Flies farthest– Climbs highest– Etc.
