"Grab the slider and spin the Earth! Watch how day turns to night as our planet rotates. The Sun stays still—we're the ones spinning!"
🌐 The AXIS: The Earth spins on an invisible line from North Pole to South Pole. That's called the axis!
⏱ Time & Rotation: One full spin = 24 hours = 1 complete day. That's why we have days!
☀️ Who's Moving? The Sun doesn't move across the sky—WE rotate! Our spot on Earth turns toward and away from the Sun.

A ballet dancer spinning with their finger on their head is like the Earth spinning on its axis! The finger is the axis, and their body is the Earth rotating.
