Seasons drawn for a 9-year-old

Chat

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:

         WINTER (Northern Hemisphere)
               \     /
                \   /
                 \ /
                  X  ← Earth (you are here)
                 / \
                /   \
         SUMMER  /     \  (Southern Hemisphere)
               \       /
                \     /
                 \   /
                  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:

  1. Draw a circle for the Sun on the left.
  2. Draw a smaller circle (Earth) moving around it in a loop.
  3. Put a tiny dot on Earth for the North Pole.
  4. Tilt the dot either toward the Sun or away from it.
  5. 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.
