Today in science, we became particles! We have been learning about how particles in solids, liquids and gases behave.

Solids

The particles in a solid are structured and organised in a consistent pattern. They cannot move around, they just vibrate, this is why solids keep their shape.

We modelled this by standing in straight lines very close together, liking our arms and bobbing up and down.

Liquids

The particles in liquids are free to move around each other, which is why liquids can flow, but they are still touching.

We modelled this by moving around each other but still making our arms touch.

Gases

The particles in gases are not attached to each other so they spread out and move around freely, this is why gases disperse.

We modelled this by running around!
