H2O is water. It has two hydrogens that are best friends with oxygen. The hydrogens come together with oxygen and the hydrogens looks like Mickey Mouse ears. Water can be a solid like ice cubes, liquid like the water we drink and gas when it boils. Water is everywhere, it is in the air, rivers, ponds, lakes and oceans. It is colorless, no smell, no taste, we drink it, play in it, cook with it and clean with it. Water is important for everyday life.
