my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Of course! The trick for a 9-year-old is: it's not about getting closer to the Sun, it's about leaning.
Here's a drawing you can copy/show her:
North Pole ALWAYS points the same way in space ↗

SUMMER WINTER
North North
(June) (December)
How to read it with her
1. Earth is like a ball on a tilted stick. The North Pole isn't straight up — it's leaning a little, like someone tilting their head.
2. That stick always points the same way (toward the North Star), even as Earth travels around the Sun.
3. So sometimes we lean IN, sometimes we lean OUT.
- Left side — June: The North Pole leans toward the Sun. The Sun hits the north straight-on, in a small, strong spot. That's our summer — hot, bright, long days.
- Right side — December: The North Pole leans away from the Sun. The Sun hits the north at a slant, spread out over a big area. That's our winter — cool, dim, short days.
The south is always opposite. When we lean in, the south leans out — so in Australia they have winter in June and summer in December!
A one-sentence script you can say
"Earth is a spinning, leaning ball. When we lean towards the Sun we get summer, when we lean away we get winter — a little like leaning towards a lamp to read."
Try it at home in 30 seconds
Get a ball or an orange and a flashlight/torch.
- Hold the ball tilted, shine the torch straight at the top — small, bright circle.
- Now tilt the top away from the torch and shine it at a slant — big, pale oval.
Direct = summer. Slanted and spread out = winter.
Want to draw it together? Have her draw the Sun in the middle, two circles opposite it, and draw the exact same tilted line through both circles. When she sees both lines are parallel, the "lean in / lean out" clicks.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
