water

Previous

A colourless, transparent, odourless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

Water is very important for life. We need water to drink, to wash our hands, to cook, to water plants and many other things. Without water, the plants would die and people and animals would go thirsty. Your body is made up of many bones. All these bones make up your skeleton. Like your body, water is made up of a skeleton of water molecules.

Water is a transparent and nearly colourless chemical substance. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms. Water is one of the most common substances on the Earth. Covering over 70% of the surface of the Earth, it is easy to find. Even in a desert it is not hard to find water, if you know where to look. Water can occur in three states: solid (ice), liquid, or gas (vapour).

Importance of water:-

Everything that is living on earth needs water to survive.  If water ceased to exist, animals, plants, people and everything else would eventually perish.

* The human body is made up of about 75% water.  Water helps our blood flow into the blood vessels and supplies vital nutrients to our bodies.

* Starting in the morning with their breakfast, kids should aim to have 6-8 drinks per day which should ideally be water, milk, fruit juice/ vegetable juices.

* Children taking part in sports or exposed to warm weather need to replenish the lost fluids by drinking more water.

Some fact about water and our body:-

* When we are born water makes up about 75% of our body weight.

* Water makes up about 60% of the body weight of older children and adults.

* Water is constantly being lost from our body so if we don’t drink enough we become dehydrated.

Water helps our body in many ways:

1. It carries nutrients to cells;

2. It helps to remove waste products from our major organs;

3. It helps us to control our body temperature.

* Water is found in all drinks and also in food. For example water is in orange juice and milk; it is also in fruits and vegetables. It is even in cheese!

* People can survive for up to 50 days without food but only a few days without drinking water.
