my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Absolutely! Here's the simple science, a drawing you can show her, and a quick "try this" activity she can do herself.
🌞 Why We Have Seasons (in 30 seconds)
It’s not because we get closer or farther from the Sun. It’s because Earth is tilted on its axis by about 23.5°.
- When your part of the Earth tilts toward the Sun, the light hits more directly → summer (longer days, warmer).
- When it tilts away from the Sun, the light hits at an angle → winter (shorter days, cooler).
- Half the year your part of the world tilts toward the Sun, half the year it tilts away.
🎨 Text Drawing You Can Show Her
Copy this and read it together:

X
- The X is Earth.
- When the top of the X (North Pole) leans toward the Sun → summer for you, winter below the equator.
- When the top of the X leans away from the Sun → winter for you, summer below the equator.
- The Sun is the big star on the left. Earth orbits around it once a year, and the tilt stays pointed in the same direction the whole time (that’s why we have seasons, not just “sun-close/sun-far”).
✏️ She Can Draw It Too!
Give her a pencil and paper, and ask her to:
- Draw a circle for the Sun on the left.
- Draw a smaller circle (Earth) moving around it in a loop.
- Put a tiny dot on Earth for the North Pole.
- Tilt the dot either toward the Sun or away from it.
- Label “Summer” or “Winter” on her side.
She’ll instantly “get it” when she sees that the tilt, not the distance, makes the difference!
Let me know if she’d like a printable worksheet version or a quick hands-on activity with a flashlight and a ball! 🌍💡
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
