my 9 year old asked why we have summer and winter. can you draw it so she gets it?
I can’t draw pictures, but you and your 9-year-old can draw it together in about 5 minutes! Here is a simple, kid-friendly way to show it.
The big idea
Earth is like a spinning top that is tilted. As it travels around the Sun, it always leans the same way. That tilt is why we have seasons — not because Earth gets closer or farther from the Sun.
Draw it together
What you need: Paper, a yellow crayon/marker, a blue crayon/marker, and something round to trace (like a cup).
- Draw the Sun in the middle of the page. Color it yellow.
- Draw Earth 4 times around the Sun, like it’s walking in a circle. (You can trace the cup for each one.)
- Draw Earth’s “axle.” On each Earth, draw a stick straight through the middle from top to bottom. Tilt the stick the same direction on every Earth (for example, always leaning to the right). That’s Earth’s tilt.
- Color the day side. On each Earth, color the half facing the Sun yellow (daytime) and the other half blue (nighttime).
- Label the seasons.
- Where the North Pole leans toward the Sun → Summer (for us in the Northern Hemisphere).
- Where the North Pole leans away from the Sun → Winter.

(Same tilt direction every time! Earth just moves around the Sun.)
(Positions 2 and 4 would be spring and fall.)
Things to tell her
- It’s the tilt, not the distance. Earth is actually farther from the Sun in July (Northern Hemisphere summer) than in January.
- Opposite seasons. When it’s summer where we live, it’s winter in places like Australia or Argentina, because they’re on the other side of Earth.
- The Sun feels stronger in summer. When your part of Earth leans toward the Sun, sunlight hits more directly and stays out longer. When you lean away, the sunlight is spread out and the days are shorter.
If you want, you can even use a flashlight (the Sun) and a globe or ball with a stick stuck through it (Earth) to show it in real life!
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
