Hey there, curious minds! Welcome to Fizz Pop Wow, the super fun 5-Minute Science Podcast, where we answer big questions with quick, exciting answers. I'm Michelle, and today's question is soaring high. How do airplanes fly without flapping their wings like birds? Let's find out!
The Science of Flight
Birds flap their wings to stay in the air, but airplanes don’t flap at all. So how do they fly? It’s not magic, it’s science! Airplanes stay in the air because of a force called lift. This happens because of the shape of an airplane’s wings. Air moves faster over the top of the wing and slower underneath. This creates higher pressure under the wing and lower pressure on top, which lifts the plane up. This idea is called Bernoulli’s Principle, and it’s the secret to how planes fly!

Materials Needed:
- A piece of paper
Steps to Follow:
- Hold the paper under your chin, letting it hang down.
- Now, blow across the top of the paper.
- What happens? The paper lifts up! That’s Bernoulli’s Principle in action.
More Than Just Lift
Flying isn’t just about lift! Airplanes also need thrust, drag, and gravity. The engines create thrust, pushing the plane forward. As it speeds up, air moves over the wings, creating more lift. Drag slows the plane down, and gravity pulls it toward the ground. A balance of all these forces keeps the airplane flying!
Airplanes and Gliding Birds
Some birds, like eagles and hawks, don’t flap much either! They spread their wings and glide just like airplanes, riding the wind to stay in the air.
Your Challenge
Try the paper experiment and explain how lift works! Next time you see a plane, think about how lift keeps it up there.

Key Takeaways
- Airplanes don’t flap their wings like birds—they use lift.
- Bernoulli’s Principle explains how fast-moving air creates lift.
- Thrust, drag, gravity, and lift work together to keep planes flying.
