my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Here's the whole thing explained, with pictures. Ask her to read the captions out loud with you. π
The short answer
Because Earth is tilted on its side β like a ball rolling around a lamp β and sometimes we lean toward the Sun, sometimes away.

Left side: our pole leans TOWARD the Sun = our summer βοΈ
Right side: our pole leans AWAY from the Sun = our winter βοΈ
And the two spots we didn't draw (top and bottom of the orbit) are March and September β that's when neither side leans much, so days and nights are about equal (the "equinox," which means "equal night").

Two things happen when we lean toward the Sun:
- The sunlight lands more directly on us β it's hotter.
- We get more hours of daylight β more time to warm up. (Winter days are short β that's why it's cold even in the sunny part of the day.)
Picture 3: The "bunched-up rays" picture (this is the cool one)
When the Sun shines straight on, the same amount of
light gets squeezed into a smaller spot = hotter.

One thing to clear up right away
β "It's summer because Earth is closer to the Sun." No! When the Northern Hemisphere has summer, Earth is actually at its farthest point from the Sun (that's early July for us). Distance barely matters β tilt is the whole reason. (And while we're at it: the seasons are caused by tilt, not by how far we are. On Mars, with almost no tilt, it barely has seasons at all!)
The sentence to memorize
"Earth is tilted, so as we go around the Sun, sometimes we lean toward the light and sometimes away β and toward means summer, away means winter."
Fun things she might ask
- "Is it winter in Australia right now?" Yes β when it's summer for you, it's winter for people near the South Pole's equator (Australia, Brazil, South Africa, Argentina). Their summer is your winter!
- "Why is the equator hot all year?" Because the equator is never tilted much toward or away β it gets straight-up sun all year. That's also why the poles are ice.
- "Can you actually feel the tilt?" If she holds a lamp in one hand and a ball in the other and walks around the lamp, keeping the ball tilted the same way, she will see the hot spot (the part of the ball facing the lamp directly) move up and down. That is literally Earth's seasons. This is the best experiment for it. π¦β½
Want me to redo the pictures in a simpler "picture-book" style, or add a diagram for the Southern Hemisphere (Australia) so she can see the two hemispheres have opposite seasons? Also β which country are you in? I'll swap the months to match your seasons.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
