my 9 year old asked why we have summer and winter. can you draw it so she gets it?
I love this question! I can't create an actual picture file here, but I can draw it for you right in this chat using text, and then give you a super simple step-by-step guide so you and your daughter can draw it together on paper!
Here is my text drawing of the real reason (it's all about the tilt, not the distance!):
SUMMER (for us!)

WINTER (for us!)
(December 21st)
How to read this drawing:
- The O in the middle is the Sun.
- The little ***** on the left and right are the Earth in June and December.
- The slanted line
/ |or\ |is Earth's "tilt stick." The Earth is always leaning over the same way, like a spinning top that's about to fall over. - When it's Summer, the top of the Earth (where we live in the Northern Hemisphere) leans TOWARD the Sun.
- When it's Winter, the top of the Earth leans AWAY from the Sun.
Now, let's draw it together! (5 minutes)
Supplies: Paper, a pencil, and a marker.
- Draw a big yellow circle in the middle of the page. Label it SUN.
- Draw a big oval loop around the Sun. This is Earth's path (orbit). Label the left side Summer and the right side Winter.
- Draw a small circle on the left side of the loop. This is Earth in summer.
- Draw a straight line coming out of the top of that little Earth, but tilt it toward the Sun (about a 23-degree angle). Draw a little arrow on top of the line pointing to the Sun.
- Draw another small circle on the right side of the loop. This is Earth in winter.
- Draw a line coming out of the top here, but tilt it away from the Sun (exactly the same angle, but it points away). Draw a little arrow pointing away from the Sun. Hint: Draw the line in the exact same direction as the first one—this is the key!
- Draw sun rays hitting the Summer Earth straight on. Then draw sun rays hitting the Winter Earth at a slanted angle.
- Label it: "Summer = direct sunlight, Winter = slanted sunlight."
The "Flashlight Trick" to explain it:
Give her a flashlight and a ball (or just a lightbulb and her fist).
- Shine the light straight down on the ball. Notice how bright and small the circle of light is? That's summer—the sun's heat is concentrated.
- Now shine the light at a slanted angle. Notice how the circle of light gets stretched out and dims? That's winter—the same heat is spread over a bigger area, so it feels colder.
Also, a fun fact to blow her mind: The Earth is actually closer to the Sun in January (winter for us) and farthest in July (summer for us)! So distance is not the reason—the angle of the light is everything.
Let me know if she asks a follow-up about why the opposite side of the world has opposite seasons! 😊
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
