my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Here is a simple explanation and a picture you can show her!
The Big Secret: Earth is Leaning!
A lot of people think summer happens because Earth is closer to the Sun. That’s actually a myth!
The real reason is that Earth is tilted like a leaning spinning top—and it stays leaning in the exact same direction all year long as it orbits the Sun.
Look at the Drawing:

Days are LONG and HOT. Days are SHORT and COLD.
How to read the picture:
In June (Left Side):
- The top half of the Earth (where North America and Europe are) is tilted toward the Sun.
- The sunbeams hit us straight-on, giving us long, warm, sunny days: Summer!
- At the exact same time, the bottom half (like Australia) is tilted away, so they have Winter!
In December (Right Side):
- Earth has traveled to the other side of the Sun, but it is still tilted in the same direction.
- Now, the top half is tilted away from the Sun. The sunlight hits at a slanted angle and spreads out, making days short and chilly: Winter!
- Meanwhile, Australia is tilted toward the Sun, having their Summer (they celebrate Christmas on the beach!).
🔦 A 10-Second Experiment You Can Do Tonight:
- Grab a flashlight (or your phone light) and shine it straight down at a table from above.
- Notice how small, bright, and intense the circle of light is? That’s Summer.
- Now, tilt the flashlight sideways so the beam hits at an angle.
- See how the circle stretches out, gets bigger, and looks dimmer? That’s Winter—the same amount of heat spread over a bigger area, so it feels much colder!
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
