Paper Airplanes – YEAH! • Excellent demo or activity to activate students brains • Use models online • Build your own paper airplane • Can be used later
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 half Make 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 board Craft wire Play dough 2 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.
