The water molecule is a molecule that's always around us. It's in us and it's around us. The water molecule, or H2O is made out of 2 hydrogen atoms, and one oxygen atom. H2O, or the water molecule is very important. Water covers 70% of the Earth and is in every living thing. We drink water, we wash with water, we even have water in our skin. Without water the Earth would not have all of this life, it would be a floating rock in space. Some of the properties of water is that it's slightly charged on both ends. Water is less dense as a solid than as a liquid. H2O stands for 2 hydrogen, hence H2. The O stands for oxygen, so that makes H2O.
