What are solid particles?

Solid particles are tiny pieces of stuff that make up things around you.

Imagine you have a big chocolate bar, and you break it into little squares, each square is like a solid particle. Now imagine breaking those squares even smaller until they’re so small you can’t see them with your eyes. That’s what solid particles are like in something like sand or soil.

When you walk on the beach, and sand gets into your shoes, that sand is made of solid particles, tiny pieces of rock and minerals. Each grain is a small, hard piece of stuff, just like those little chocolate squares. You can’t see them all separately, but together they make up the whole sandy path.

If you shake up a box of marbles or beads, they move around freely, but they stay as solid particles, they don’t melt or mix into one another like liquid or gas. They just bounce and slide, staying who they are.

So next time you feel sand in your shoes or see dust floating in the air, remember, that’s solid particles, tiny bits of stuff doing their own little dance!
