1. Your Challenge… Paper Airplanes!

2. Did you know…  Chicago's O'Hare International Airport is the world's busiest airport. An airplane takes off or lands every 37 seconds.  Chicago's O'Hare International Airport is the world's busiest airport. An airplane takes off or lands every 37 seconds.  Orville Wright was at the controls during the Wright Brothers famous flight. The flight lasted only 12 seconds  Amelia Earhart was the first woman to receive the Distinguisjed Flying Cross which she was awarded as the first woman “aviatrix” to fly solo across the Atlantic Ocean

3. First off…How does a paper airplane fly?   4 forces…

4. Drag (Wind Resistance) The resistance to moving through the air, caused by air acting in the opposite direction of the motion. (push your hand through the air, palm down…now slice the air with your hand at it’s side….feel the difference?) Thrust The “power” pushing the plane forward, if the thrust is bigger than the drag, the airplane moves forward

5. Gravity The plane getting pulled downward Lift When the force pushing under the wings, upwards is bigger than the force of gravity, you have….. TAKE OFF!

7. How far can you make your airplane go?   You can choose for different paper airplanes and directions to make…   OR   You can design your own!
