What are dust particles?

Dust particles are tiny bits that float around in the air and stick to everything.

Imagine you have a big bag of sugar. You shake it up, and some grains fall out, those are like dust particles. They're so small, you can't see them with your eyes alone, but when they gather together, you can spot them as a cloud or a smudge on a window.

Dust comes from many places:

• When people brush their hair or move around, tiny bits of skin and clothes float into the air.
• Floors get dusty because of tiny pieces of stuff like paper, fabric, and even little bits of food.

You find dust everywhere! On your toys, on your bed, even inside your favorite book. Sometimes you can see it when sunlight shines through a window, it looks like a sparkle in the air.

Dust isn’t special or magical; it's just something that happens all around us every day.
