Why Does a Kite Need Wind?

What Crafty Clover says in this video

Intro

Hi! I'm Crafty Clover! Let's discover something amazing. Why does a kite need wind?

The Big Idea

A kite is like a wing on a string. Moving air hits its tilted face and slides over the top. The difference in push lifts the kite up, against gravity! Let's find out how it works, in three easy steps!

Step 1

Step one: the sail tilts! The bridle is the little set of strings that holds the kite's face at an angle to the wind. Without that tilt, the kite would just flop around.

Step 2

Step two: the air splits! Some air hits the front of the kite, and some races over the top. That makes an upward push! It's the same trick that helps airplane wings work!

Step 3

Step three: lift beats weight! When the upward push gets bigger than the kite's weight, up it goes! The tail adds a little drag, so the kite keeps facing the breeze instead of spinning. That's why a kite needs wind, or a kid running fast.

A Closer Look

Let's take a closer look at a kite! The sail is the part that catches the air. The spars give it shape, and the bridle sets the tilt. The tail steadies it, and the flying line holds it. Every part has an important job to do!

Quick Facts

Quick facts! A box kite can fly in lighter wind, because it has more faces. Too much wind can snap a cheap spar. The same tilt-plus-moving-air idea lifts airplanes and hang gliders. Stay safe: fly in an open field, far from streets, power lines, and storms.

Think Like a Scientist

Now, think like a scientist! On a gentle-breeze day, try a kite with a tail and one without, in an open field with a grown-up. Which one stays facing the wind? What job did the tail do? Write down what you notice! Scientists always write down what they see. Have fun!
