my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Great question! Here’s how I’d explain it to a 9-year-old.
Big idea: Earth is like a spinning top that is tipped over a little. That tilt gives us seasons — not Earth getting closer to or farther from the Sun.
Here’s a simple sketch:
SUNLIGHT → → → → → →
OUR SUMMER
(North Pole leans toward the Sun)
N

🌍 ← sunlight hits us more straight-on

S
OUR WINTER
(North Pole leans away from the Sun)
N
\
🌍 ← sunlight hits us at a slant
/
S
In summer, sunlight hits our part of Earth more directly, and the days are longer.
In winter, sunlight hits us at a slant, and the days are shorter.
As Earth travels around the Sun, it keeps leaning the same way. So sometimes our half of Earth leans toward the Sun — summer — and sometimes it leans away — winter. The other half of Earth gets the opposite seasons.
☀️ SUN
June: Earth here December: Earth here
North leans toward Sun North leans away from Sun
Fun fact: Earth is actually closest to the Sun in January, so being close isn’t what makes summer. The tilt is the big reason.
Try this: put a pencil through a ball, tilt the pencil, and shine a flashlight on it. Move the ball around the flashlight while keeping the pencil pointing the same direction. She’ll see which side gets more direct light — that side is having “summer.”
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
