my 9 year old asked why we have summer and winter. can you draw it so she gets it?
Great question! It’s all about Earth’s tilt. Earth is like a spinning top that leans a little bit. It never stands straight up. As Earth goes around the Sun, that lean always points the same way. So sometimes your half of Earth leans toward the Sun, and sometimes it leans away.
Here’s a simple drawing you can show her:

See the stick through Earth? That’s Earth’s axis. The N is the North Pole. Notice the stick is tilted the same way in both pictures.
- In the summer picture, the North Pole leans toward the Sun. Sunlight hits the Northern Hemisphere more straight-on, like a flashlight pointing right at it. Days are longer. That makes summer.
- In the winter picture, the North Pole leans away from the Sun. Sunlight hits at a slant, like a flashlight shining from the side. Days are shorter. That makes winter.
The Southern Hemisphere (like Australia) has the opposite seasons. When we have summer, they have winter.
It’s not because we’re closer to the Sun. In fact, Earth is closest to the Sun in January, which is winter in the Northern Hemisphere!
Try this with her: Get a flashlight and a ball. Shine the flashlight straight at the ball → bright, small hot spot. Shine it at a slant → the light spreads out and is dimmer. That’s what the tilt does to sunlight.
The catch: The Earth is closest to the sun in early January, in the northern winter: the seasons come from its tilt.
