Sphere

A sphere is like a ball that you play with or see in the playground. It's a really special shape that's round all the way around, and it's the same distance from the center to every point on its surface. Think of it like a planet, like Earth or Mars. When you look at a round globe, that's actually a sphere. When you touch a sphere, it feels smooth and curved, like a ball. And you can roll a sphere around on the ground, just like you do with a ball. The sphere is a very important shape, and it's used in lots of different things, from sports to science!
