Matter can be a solid, liquid or gas.
A solid holds its shape.
A table is a solid.
Ice is a solid.
A car is a solid.
Matter can be a liquid.
A liquid changes shape.
It becomes the shape of the thing that is holding it.
Water, milk, and orange juice are liquids!
Matter can be a gas.
We cannot see a gas.
Air is a gas.
We can fill a balloon, a tire and a bubble with gas!
