2. Water can take many forms. We see water every day. We see it at the beach. The Gulf of Mexico is liquid water! Water can be hard as a rock. When it is frozen, water is ice. You may have seen ice in a cup of soda. Frozen water, or ice cubes, keep other liquids cool. When ice cubes melt, they become liquid water again. If the pool of melted water is not wiped up, it will disappear after some time. Do you know where it goes? It becomes something else. It becomes water vapor, or a gas, and disappears into the air. There is water vapor in clouds. Water can be liquid, solid, or a gas.
