What makes a paper airplane fly? Long flights come when these four forces—drag, gravity, thrust, and lift—are balanced. Materials Per Class: examples of paper airplane instructions downloaded from paper plane-making websites: see Other Resources below Per student: 3 sheets of paper preferably recycled or reused scissors glue or tape markers for decoration paper clip optional Key Questions Why did some planes fly better than others?
What To Do Preparation: Print out various examples of paper airplane instructions and set them up throughout the classroom as stations. Their hypothesis should be based on what they have learned about the four forces of flight. Part 2: Hand out the materials to the students. Each student is to design and build their own paper aircraft, keeping in mind the four forces affecting flight. Two awards will be given: 1 the furthest distance travelled; and 2 the fanciest flight spins, loops, spirals, etc.
Students are allowed to make up to 3 airplanes but only 1 can be entered into the contest. No other sheets of paper will be handed out. Allow 25 minutes for design and building and 15 minutes for testing. Extensions Explain how you accounted for each of the four forces of flight while building your model.
What could you do differently? How could you incorporate these different features into your design?

The Science Behind Paper Airplanes Depending on the aerodynamic design, paper airplanes can fly fairly far and glide through the air with ease. Paper Airplane Designs Most kids, at some point, have had their parents make them paper airplanes or they learned how to make their own.
How Far will it Fly? You can still feel the air, but your hand is able to move through it more smoothly than when your hand was turned up at a right angle. How easily an airplane moves through the air, or its aerodynamics, is the first consideration in making an airplane fly for a long distance. Planes that push a lot of air, like your hand did when it was facing the side, are said to have a lot of "drag," or resistance, to moving through the air.
If you want your plane to fly as far as possible, you want a plane with as little drag as possible. A second force that planes need to overcome is "gravity.
Thrust is the forward movement of the plane. The initial thrust comes from the muscles of the "pilot" as the paper airplane is launched. After this, paper airplanes are really gliders, converting altitude to forward motion. Lift comes when the air below the airplane wing is pushing up harder than the air above it is pushing down. It is this difference in pressure that enables the plane to fly.
Pressure can be reduced on a wing's surface by making the air move over it more quickly. The wings of a plane are curved so that the air moves more quickly over the top of the wing, resulting in an upward push, or lift, on the wing.
A long flight occurs when these four forces — drag, gravity, thrust, and lift — are balanced. Some planes like darts are meant to be thrown with a lot of force.
Because darts don't have a lot of drag and lift, they depend on extra thrust to overcome gravity. Long distance fliers are often built with this same design.
