Kavi's Deep-Down Dig
Kavi pulls on a hard hat and grabs a torch 🔦. "Did you know the Earth is full of useful treasure?" Kavi taps a wall of rock 🪨. "We build with rock, we dig metals like iron and gold out of special rocks, and far below we find oil and gas we burn for energy." Then Kavi brushes the dust off a stone and gasps — a fossil! 🦴 "This shell turned to stone over millions of years. Let's explore what Earth gives us!"

A peek inside
Kavi holds up a heavy iron nail 🔩. Where did the iron come from?
Metals like iron are dug out of special rocks called ore, deep in the ground.
