my 9 year old asked why we have summer and winter. can you draw it so she gets it?
I can't make actual pictures, but here's a diagram you can sketch together — drawing it with her is honestly the best version of this.
☀️ THE SUN (it just sits there, not moving)

tilted AWAY from the Sun tilted TOWARD the Sun
(December) (June)
The three things to tell her:
- The Earth is a little bit crooked — it spins leaning over, like a top that got bumped. It leans the same way all year long.
- For half the year, our half of the Earth leans toward the Sun. That's summer. The other half of the year we lean away. That's winter.
- Leaning toward the Sun does two things: the sunlight hits us more straight on (stronger), and the days get longer. Both make things warmer.
The demo she'll remember: In a dark room, shine a flashlight straight down on the table — you get a small, bright circle. Now tilt the flashlight so the light comes in at a slant — the light spreads into a big, faint, stretched-out oval. Same amount of light, but spread over a bigger area, so it's weaker. That's exactly what winter sunlight is.
Two facts that will blow her mind:
- It's the opposite season in Australia right now — when it's winter here, kids there are at the beach.
- The Earth is actually closest to the Sun in January. So seasons have nothing to do with how far away we are — it's all the lean. (Good chance to show her that the "closer = hotter" idea everyone guesses is wrong.)
If you want to draw the real version: a big yellow circle in the middle, a big oval orbit around it, and Earth drawn at four spots on the oval with a line through it always leaning the same direction (point it toward the top-right corner every time). Then label the two spots where the lean points at the Sun versus away from it.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
