The story for a 9-year-old

  1. Earth is tilted, like a spinning top leaning to one side.
  2. The tilt never changes. As Earth travels around the Sun (one year), it always leans the same direction.
  3. In June, the top half of Earth leans toward the Sun. The sunlight hits it more directly, and the days are longer. That's summer in the north.
  4. In December, the top half leans away. The sunlight is weaker and the days are shorter. That's winter.
  5. The bottom half is the opposite. When it's summer in the USA, it's winter in Australia!

Why does leaning matter?

 Straight-on light:         Slanted light:
 
   |||||                    \\\\\\\\\
   |||||                     \\\\\\\\\
  β”Œβ”€β”€β”€β”€β”€β”                  ──────────────

  β””β”€β”€β”€β”€β”€β”˜                  ──────────────

Direct light is concentrated and warm. Slanted light is spread over a bigger area, so it's weaker. It's like a flashlight pointed straight at a wall versus at an angle.

Common myth to bust 🚫

Many people think summer happens because Earth is closer to the Sun. It's not! Earth is actually a little closer to the Sun in January, when it's winter in the north. The tilt is what matters.

Try it at home (2 minutes)

  • Use a lamp with no shade as the Sun and an orange or ball as Earth. Stick a pencil or skewer through it as the axis.
  • Tilt the pencil and keep it pointing at the same corner of the room.
  • Walk the orange in a circle around the lamp. She'll see the top half lean toward the light, then away.

Want me to make a printable version, or a simple SVG image she can color in?

The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
