Water is a very simple but important part of our lives. Water is made up of two elements, hydrogen and oxygen. When they are combined they form H2O. Water is all around us and comes in many forms such as liquid, ice, snow and steam. We need water to live because it helps us stay healthy by keeping our bodies hydrated and it also helps clean up messes. Water can also be used to generate electricity and to make things grow. To learn more about water, you can look at data pages about water which will show facts about different kinds of water like the amount of water in the ocean, or the different types of water used for different purposes.
