What are non-uniform shapes or materials?

Non-uniform shapes or materials are things that don’t look exactly the same all over, like a cookie that’s thicker on one side than the other.

Imagine you have a blanket that's soft and fluffy in some spots, but rough and scratchy in others. That’s what non-uniform means, not the same everywhere.

Think of a playground: one part has smooth slides, another has bumpy tires, and then there’s a squishy cushion area. Each part feels different under your feet, just like non-uniform materials feel different in different places.

Take a sponge, it's all squishy and wet on the outside, but inside, it might be dry or even have some hard spots from where it was pressed before. That makes it non-uniform, because not every part of it is the same.

So, non-uniform things are just like that, they’re fun to touch and explore because you never know what you’ll feel next!
