One sunny afternoon, Sammy visited his grandfather’s workshop. On a dusty shelf, he found a small square panel with shiny parts. "Grandpa, what’s this?" he asked, holding it carefully.

His grandfather smiled and said, "That’s a tiny solar panel, Sammy. It uses sunlight to make power. Let me show you." They placed the panel near the window, and Sammy saw a small light turn on.

"So, the sun helps it work?" Sammy wondered aloud.

"Exactly," his grandfather nodded. "The sun’s energy can power things without using electricity from wires. It’s clean and won’t run out anytime soon."

Sammy spent the afternoon learning and asking questions. When it was time to leave, he looked out the window at the bright sky. "I want to find more ways to use sunlight," he said, feeling excited about the world.
