What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What is passive solar design?

The Big Idea

Some buildings are designed to catch the Sun's free heat. They do it with no machines at all. That is called passive solar design!

Windows to the South

Step one: windows to the south. Passive solar design uses a building's shape and position to use the Sun's free heat without machines. Large windows face south to let in winter sunlight.

Heavy Materials

Step two: heavy materials. Heavy materials like stone or concrete soak up heat during the day. They release it at night.

Roof Overhang

Step three: a roof overhang. A roof overhang blocks the high summer Sun. It is smart planning, not gadgets.

A Closer Look

Let's take a closer look! South windows catch winter sun. Stone soaks up heat. At night, it gives the heat back. An overhang blocks summer sun.

Quick Facts

Quick facts! People have built homes this way for thousands of years. South windows catch winter sunshine. Stone stores heat for the night. Overhangs block the high summer Sun.

Think Like a Scientist

Now, think like a scientist! Observe a sunny room. Where does the sunlight fall in the morning? Where does it fall in the afternoon? What warms up? Tell a grown-up what you discover!

Outro
