Paper airplanes are fun to build and fly, but they are also a great way to explore aerodynamics, force, and motion. In this paper airplane science fair project, students test different airplane designs to see how wing shape, weight, and launch force affect how far a plane flies.
Paper Airplane Science Fair Project
By experimenting with lift, drag, and thrust, kids can turn a simple paper airplane into a real science experiment. You can even build a paper airplane launcher to test your designs and compare results.
This hands-on STEM activity is perfect for science fairs, classroom investigations, or at-home experiments.

- Paper clips
- Rubber bands (for optional launcher)
- Printable Instructions and blank graph (Join us in the Library Club)
Tips To Set Up Your Science Project
1 Create different airplane designs: Fold several paper airplanes with different wing sizes, shapes, and body lengths. Keep your designs consistent by using the same paper size and folding techniques. Wing design matters! Our airplane templates will help.
2. Set up a testing area: Use an open space without wind interference. Mark your starting point, and throw each airplane with the same amount of force to keep the test fair.
💡 See our tips for throwing paper airplanes here. Remember, you’ll want to launch your airplane the same way every time!
3. Measure and record data: Use a ruler or measuring tape to measure how far each airplane flies. Time how long each plane stays in the air with a stopwatch. Record your results in a notebook to create a data table or bar graph later (see below for an example).
4. Analyze the data: Repeat the test a few times for each airplane design to ensure accuracy. Calculate the average distance and flight time for each design.
5. Use a launcher (optional): Want to add more fun? Use a rubber band launcher to propel your planes and test whether they fly farther than hand throws. You can check out our Airplane Launcher Tutorial here.
The Science of Paper Airplanes (Aerodynamics)
Aerodynamics: This project helps you understand how air moves around an object. The wings of the paper airplane interact with the air, creating lift to keep the plane flying. At the same time, drag slows the plane down.
Thrust: Whether using your hand or a launcher, the force that moves the plane forward is called thrust.
Lift and Drag: Different wing designs create varying levels of lift and drag. Large wings might create more lift, but also more drag. Small, streamlined designs might fly faster with less drag but could lose altitude more quickly.
Variables to Test in a Paper Airplane Experiment
To turn this activity into a real experiment, students should change one variable at a time and measure its effect on flight.
Here are a few ideas to test:
Wing Size
Do airplanes with larger wings fly farther or stay in the air longer?
Paper Type
Does heavier paper help a plane fly farther, or does it reduce flight time?
Added Weight
Try attaching a paper clip to the nose of the plane. How does weight affect the flight distance?
Launch Force
Compare hand throws with a rubber band launcher to see how extra thrust changes the results.
Wing Angle
Adjust the wing tips slightly up or down and observe how it changes lift and stability.
Testing these variables helps students understand how aerodynamics and airplane design affect flight performance.
Turn it into a science fair project
💡 This paper airplane activity is a great way to use the scientific method and explore how airplane design affects flight.
Create a hypothesis
Start with a prediction about what you think will happen. For example:
“If I make a paper airplane with larger wings, then it will fly farther because larger wings create more lift.”
Test different variables
Change one design feature at a time and observe how it affects flight. Possible variables include:
- wing size or shape
- paper type
- added weight (such as paper clips)
- wing angle or body length
Choose an independent variable (what you change) and a dependent variable (what you measure).
For example, if you change the wing shape of the airplane (independent variable) and measure flight distance or time in the air (dependent variable), you can learn how airplane design affects performance.
Collect data
Test each airplane design several times to improve accuracy. Measure how far each plane flies and how long it stays in the air. Record the results in a notebook or data table.
Analyze and present results
Calculate the average distance or flight time for each design. Then compare the results to determine which design performed best.
Students can present their findings on a science fair board, in a report, or by creating a graph that shows the results of their experiment.
Example results graph
The bar graph below shows the distances traveled by different paper airplane designs. Each airplane design (such as “Wide Wings” or “Narrow Wings”) appears on the x-axis, while the y-axis shows the distance flown in feet.
By comparing the bars, you can easily see which airplane design performed best. In this example, the Narrow Wings design flew the farthest at 15 feet, while the Long Body design traveled the shortest distance at 9 feet.
Aviation Inspiration: Amelia Earhart and the Science of Flight
One of the most famous pioneers in aviation history was Amelia Earhart. She became the first woman to fly solo across the Atlantic Ocean in 1932 and helped inspire generations of pilots, engineers, and scientists.
Amelia Earhart helped scientists and engineers better understand long-distance flight and navigation, making her an important figure in the history of aviation science.
Earhart’s flights depended on the same aerodynamics principles we explore when building paper airplanes.
To fly safely and efficiently, pilots must understand the four forces of flight:
- Lift – the upward force created by the wings
- Thrust – the forward force from the engines
- Drag – air resistance that slows the plane
- Gravity – the force pulling the plane toward Earth
Aircraft designers carefully shape wings to increase lift while reducing drag. These same ideas apply when students test different paper airplane designs to see which flies the farthest or stays in the air the longest.
Earhart’s most ambitious journey was her 1937 attempt to fly around the world in a Lockheed Electra airplane. During the final leg of the trip, her aircraft disappeared near Howland Island in the Pacific Ocean. What happened next remains one of aviation’s greatest mysteries.
Students can investigate the clues from her final flight in our Amelia Earhart mystery investigation activity, where they analyze radio messages, weather conditions, navigation challenges, and different theories about her disappearance.
You can also explore more inspiring scientists and pioneers in our women in STEM scientists collection, which highlights inventors, mathematicians, astronauts, and engineers who helped shape modern science.
Try This Extension
After testing paper airplanes, ask students:
- Which airplane design produced the most lift?
- Which flew the farthest?
- How might real aircraft designers test wing shapes?
Then introduce Amelia Earhart and discuss how real pilots rely on these same science principles during flight.
