Rin and the Cool Roof

Name: Rin and the Cool Roof
Author: An original story by Hoot Tales

Rin, a Thai girl, sits beside three wooden toy houses in a hot afternoon yard, touching a roof and thinking.

One hot April afternoon, the roofs of Rin's three wooden toy houses were almost too warm to touch. 'Could color and shade make the inside cooler?' she wondered.

Rin and Uncle arrange dark, white, and shade-panel model roofs on an outdoor table while planning the experiment.

She made three roofs: dark, white, and white with a shade panel. Uncle pointed out that the last one changed two things at once, so Rin decided to finish the color test first.

Rin times two equal model houses with dark and white roofs and matching picture thermometers under the same sunlight.

Rin placed equal houses in the same sunlight at the same time, added matching picture thermometers, and kept the doors shut. When time was up, the white-roofed house was cooler.

Rin compares two white-roofed model houses, one with a raised shade panel, and happily adds colored result strips.

Next she used white roofs on both houses and added a raised shade to only one. The air gap made that house cooler still. Rin recorded the result with color strips.

Rin and her family stand beside a pale-roofed chicken coop with raised shade at evening while hens rest comfortably.

Her family used the idea on their small chicken coop, giving it a pale roof and airy shade. The hens rested more comfortably. Rin posted a picture reminder: change one thing, then observe.
