How Do Tall Wind Towers Keep Desert Houses Cool?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do tall wind towers keep desert houses cool?

The Big Idea

Tall wind towers keep desert houses cool by catching breezes and sending them down into the house! People in parts of Iran and the Middle East call them windcatchers. It is air conditioning without electricity.

Catch the Breeze

Step one: catch the breeze. Builders put tall towers on roofs. Even a gentle breeze at the top is caught by the tower. The tower sends that air down into the house.

Hot Air Escapes

Step two: hot air leaves. Hot air inside the house rises, and it escapes through other openings. That pulls fresh air in, so air keeps moving through the rooms.

Water Cooling

Step three: add water. Some towers also pass the air over water, and evaporation cools it even more. It is like a natural fan that needs no plug.

A Closer Look

Let's take a closer look! The tower rises above the roof. Fresh breeze flows down inside. Water can cool it a bit more. And hot air rises out through openings.

Quick Facts

Quick facts! Some windcatchers have been working for hundreds of years. They use only wind and the way hot air rises. That makes them great for saving energy and keeping people comfortable on hot days. Great ideas can be very old.

Think Like a Scientist

Now, think like a scientist! Stand a paper tube upright and hang a thin tissue strip just inside the top. Blow gently across the opening. Does the strip flutter upward? Moving air can pull more air along. Share what you discover with a grown-up.
