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 three things to tell her:**

1. 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.
2. 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.
3. 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.
