Here’s a kid-friendly way to explain it, plus a simple “drawing” you can recreate on paper.

### The short answer
Earth is **tilted** like a spinning top that’s leaning. As we go around the Sun, sometimes your half of Earth leans **toward** the Sun (summer) and sometimes it leans **away** (winter).  
- **Summer:** Sunlight hits you more straight-on and days are longer.  
- **Winter:** Sunlight hits you at a slant and days are shorter.

*(The tilt doesn’t change direction—it stays pointing the same way in space while Earth orbits.)*

           Winter side (leans away)          Summer side (leans toward)

              /    🌍    \  ← Earth spins       /    🌍    \  ← Earth spins
             /  (tilted)  \   on its axis      /  (tilted)  \
            /              \                  /              \
           /                \                /                \

**How to draw it with your 9-year-old:**
1. Draw a big **orange circle** = Sun in the center.
2. Draw **two Earths** on opposite sides of the Sun.
3. On each Earth, draw a **line through the middle** (the axis) that **leans the same direction** on both—like a slanted pole.
4. On the Earth **closer to the Sun with the top tilted toward it**, color the side facing the Sun **yellow** and write **SUMMER**.
5. On the Earth **on the other side**, color the side facing away from the Sun **blue** and write **WINTER**.
6. Add **little stick figures** on each: summer one with sunglasses, winter one with a scarf.

### A 30-second demo
Hold a **ball** (Earth) with a **pencil through it** (the axis) tilted about 23°. Shine a **flashlight** (Sun) on it.  
- Tilt the top of the ball **toward** the light → that side is “summer.”  
- Rotate the ball around the light while keeping the pencil pointing the same way → now the other side is “summer.”  
That tilt-staying-same is the whole secret!
