my 9 year old asked why we have summer and winter. can you draw it so she gets it?
I can’t literally pick up crayons, but I can draw with emoji and text! Here’s the picture to show your 9-year-old.
First, the big idea
Earth spins like a basketball that is leaning over about 23°. And here’s the trick: it never straightens up. Its North Pole always points the same direction in space (toward the North Star).
As Earth travels in a big circle around the Sun over 12 months, that lean means:
- Sometimes the North Pole leans toward the Sun → Summer
- Sometimes it leans away → Winter
(It’s the opposite in Australia!)

Why is winter colder? It’s not mainly about distance. It’s the angle of the light.

Straight punch! Spread out & weak!
(hits one spot hard) (hits same spot gently)
When rays come in straight, they heat us up fast and the days are longer. When they come in at a slant, the same energy is spread over more ground, and the days are shorter.

The Earth is always leaning the same direction. The orbit just carries us to the “toward” side, then the “away” side, then back again.
One-sentence version for her
“We have summer and winter because Earth is a tilted spinning top traveling around the Sun. Half the year our half leans in for a direct sun-bath; the other half we lean back and get the slanted leftovers.”
If she wants to see it with a real flashlight and an orange, you can shine the light straight on (summer) and then tilt the orange away so the light hits at a slant (winter) — same idea!
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
