What is liquid?

Liquid is something you can pour that fills up whatever container it’s in, just like water from a cup to a glass.

Imagine you have a bowl full of cereal and milk. The milk moves around the cereal easily, that’s because it's a liquid. It doesn’t stay in one shape like the cereal does; instead, it takes the shape of whatever holds it.

Liquids can flow because their parts are not all stuck together. Think about when you pour juice from a bottle into your glass, the juice moves smoothly and fills up the glass. This is similar to how sand moves in an hourglass, but liquids flow more easily than sand does.

You see liquids everywhere! Juice, oil, soda, even honey are all kinds of liquids. They’re like the friendly cousins of solids, they can move and change shape, but they still keep their own space, just like how you fit into your favorite pair of pants.
