my 9 year old asked why we have summer and winter. can you draw it so she gets it?
I can't produce a real image file, but I can give you a diagram you can sketch on paper in about 2 minutes while you explain it. Here it is.
The one-sentence answer
The Earth spins on a tilted stick, and as it travels around the Sun, one half leans toward the Sun (summer) while the other leans away (winter).

Earth goes around the Sun once a year. The tilt never changes direction — the stick always points the same way, like a spinning top that leans.

In June the top of the Earth leans into the sunshine. In December it leans away.
The flashlight test (do this with her)
- Shine a flashlight straight down on the table → small, bright, hot circle.
- Tilt it to the same height → the same light spreads into a big, weak oval.
That's the whole secret. In summer the Sun's light lands on us straight-on and concentrated. In winter it lands at a slant and spreads out. Same Sun, thinner beam.
Two more things that make summer feel like summer:
- Longer days — in June the Sun is up way more hours, so there's more time to warm up.
- Higher Sun — it climbs higher in the sky, so it shines through less atmosphere.
Fun facts to blow her mind
- It's summer in one half of the world and winter in the other at the same time. When it's July at your house, kids in Australia are in winter coats. That's the best proof that it's about tilt, not distance.
- Earth is actually closest to the Sun in early January — right in the middle of northern winter. So "closer to the Sun" is not the reason. Kids' books get this wrong all the time.
How to draw it on paper
Circle for the Sun. Draw a diamond of four Earths around it. Then draw one big Earth off to the side with a stick through it, tilted, and a straight line of arrows from the Sun. Label the two ends "summer" and "winter." That's the whole lesson in one page.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
