Why Do Paper Planes Fly Steadier When Their Wings Tilt Up Into a Shallow V?
Wings tilted up in a shallow V help a plane stay steady. If it rolls, the low wing gets more lift. That swing rights the plane! Dihedral means wings tilt up like a shallow V.

Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do paper planes fly steadier when their wings tilt up into a shallow V?
The Big Idea
Wings tilted up in a shallow V help a plane stay steady. If it rolls, the low wing gets more lift. That swing rights the plane!
A Shallow V
Step one: a shallow V. When wings are tilted up in a shallow V, a plane that rolls to one side can right itself. This shape is called dihedral.
More Lift Below
Step two: more lift below. The lower wing meets the air at a steeper angle than the high wing. So it gets more lift and swings back up.
Real Planes Use It
Step three: real planes use it. Many real airplanes have dihedral, especially small ones. It helps a plane stay steady with less work from the pilot.
A Closer Look
Let's take a closer look! Wings tilt up a little. One wing dips. The low wing lifts more. The plane rights itself.
Quick Facts
Quick facts! Dihedral means wings tilt up like a shallow V. The lower wing gets more lift. Many small planes use dihedral. It means less work for the pilot.
Think Like a Scientist
Now, think like a scientist! Make two paper planes. Fold the wings of one flat, and tilt the wings of the other into a shallow V. Test each three times. Which flies straighter? Throw away from people and pets, and never at faces. Share what you discover with a grown-up.
Outro
Dihedral tilts wings into a shallow V so a rolled plane's lower wing gets more lift and swings upright again, which helps many small airplanes stay steady with less work from the pilot. Science is amazing! Keep asking questions! There is always more to discover, and you are a great science explorer! Ask a grown-up to help you compare flat wings and shallow-V wings safely.
