How Does Dust and Smoke - Science Work?

Dust and smoke are like tiny friends that float around when things get jiggled or heated up.

Dust is like little pieces of stuff that come off things, think about when you shake a rug full of dirt, and the bits fly into the air. That’s dust! It's made from tiny parts of things like skin, fabric, and even old cookies in the kitchen.

Smoke is what happens when something burns, like when your favorite cookie burns in the oven, or when you light a candle. The fire pushes out little invisible friends called particles, which are so small they float around until they settle down.

When dust and smoke mix together, like on a foggy day or after a big fire, it's like having lots of tiny friends floating around in the air. They can make things look hazy, like when you're trying to see through a smoky room or a dusty attic.

You can feel this too! When you're outside and there's a lot of smoke from a fire, it might be hard to breathe, just like how it feels when you’re in a dusty room with no windows.
