The book, the pencil and the desk

are solids.

You can hold solids but you can’t walk

through them because they are made of

tiny parts that stick together closely.

Water, oil and juice are liquids.

You can feel liquids in your hands

but you can walk through them

because they are made of tiny parts

that are close but don’t stick together.

The air we breathe is gas.

You can’t touch or hold gas but you can

easily walk through it because it is made

of parts that are spread far apart from

each other.
