my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Yes. Summer and winter happen because Earth is tilted, not because we get closer to the Sun.

Earth spins like a top that is leaning a little (about the same lean all year). As we go around the Sun:
- When your half of Earth leans toward the Sun, sunlight hits more straight-on and days are longer. That is summer.
- When your half leans away, sunlight comes in at a slant and days are shorter. That is winter.
- The other half of Earth has the opposite season at the same time. When it is summer where you live, it is winter on the other side of the world.
A quick demo: shine a flashlight straight down on a paper, then tilt the paper. Straight-on light is brighter and warmer. Slanted light is spread out and weaker. That is winter light.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
