The vapor rises. It is easy to see

the vapor from boiling water.

A lot of water! Water makes up

a large part of you, too. Sorry, you

can't live without it. Let's see how

water can change forms.

Water can become so cold that

it freezes into ice and becomes

Ice and snow are a lot of fun.

These children think it's okay to

the mountains.

This river is very full. It is nearly

overflowing. Water in its liq_uid form

might seem very angry!
