Kavi Follows the Beam
Kavi points a torch 🔦 across the dark room and watches the beam shoot out in a straight line. "Look — light doesn't just appear on things," hoots Kavi. "It starts at a source, travels out, bounces off my teddy 🧸, and lands in my eyes 👀 — that's the moment I see it! Let's follow light all the way from the source to our eyes."

A peek inside
Kavi reads a book 📖 under a bright lamp. Trace how the light reaches Kavi's eyes.
The lamp is the source. Its light travels to the book, bounces off it, and lands in Kavi's eyes.
Try this at home: What do we call something that makes its own light, like the Sun or a lamp?
