Sources of water
There is plenty of water present on the earth. Water is all around us. We find water in rivers, ponds, wells, lakes and undergrounds. Most of water comes from rain. We make wells and tube wells to get water from the ground. The water that we drink is called Potable water.
Properties of water
Water is only substance on the earth which is found in solid, liquid and gaseous forms simultaneously.
It has no colour, taste and smell.
Clean and safe water
Although plenty of water is present on earth but Potable clean water is not sufficiently present on the earth. We must drink clean water .Unclean water is not safe to drink. It can make us sick. Polio, Typhoid, Cholera are same contagious diseases which is spread by unclean water. The water we get in our taps may not be clean. Therefore we must boil and filter the water to make it safe for drinking. Boiling kills the bad germs in water. We must store the water in clean vessels and cover them with lids.
Saving Water
Water is a very precious Resource. It is very important to life. We must not waste it. Keep the tap closed when you are not using it. We should reuse our household unclean water in our kitchen garden. Let us do our best to save every drop of water.
