Dust

What little parts can you find in your bedroom, in your classroom, even in outer space? Dust!

Dust is tiny pieces of matter. You can find it in the air. It can be made up of our old skin. Fibers from our clothes also make up dust.

Dust mites are little bugs. They live in carpets and on beds. They eat dust in our houses. Dust mites can cause an allergy.

Dust lives in outer space, too. Mars has big dust storms. Dust makes up the tails of comets. Dust is everywhere!
