Paper airplane science fair test

How to make it

1. 

   1

   Ask the question

   Write it down: which paper airplane design flies the farthest?

2. 

   2

   Make a guess

   Write your hypothesis, your best guess and why. That's what judges look for first.

3. 

   3

   Fold 3 designs

   Fold a classic dart, a wide-wing glider and one of your own. Same paper for all 3.

4.

   Set up the runway

   Tape a start line on the floor in a long hallway or a gym. No wind, so stay indoors.

5.

   Fly and measure

   Throw each plane 5 times from the same spot with the same throw. Measure to where it first lands.

6.

   Average the results

   Add the 5 distances for each plane and divide by 5. Make a bar graph.

   Explain what happened

   Write which won and why. Narrow darts cut through the air fast. Wide wings make more lift, so gliders float longer but slow down.
