In class 3 Science Water pollution, students will understand why we need to purify water before drinking and the different techniques purify water at home.

Water Pollution

Most of the Earth is covered with water. Most of the water is found in the oceans and seas. We cannot use water from the oceans as it has lots of salt in it. We get fresh water for use from Rivers, lakes, springs and ponds. Clean water has no smell, taste and colour.

Polluted Water

When rivers pass through cities, dirt, mud, plastic, paper, oil, garbage and chemicals mix in the water, making it water polluted. The harmful things that make water polluted are called Pollutants.

Polluted water is not safe for drinking. These pollutants can make water look and smell bad.

 

Pollution Affects Us

Polluted water smells very bad and has many germs growing in it. Mosquitos and insects breed in polluted water and spread various diseases. Humans as well as animals also get sick when they use this polluted water. Even plants do not grow well with polluted water.

Purifying Water

We need to purify water to make it fit for drinking.

Some people boil tap water. When water boils, it becomes very hot and the germs are killed.

Many people use special water filters to purify water. These filters have layers of sand, gravel and charcoal, which helps to filter out dirt in the water. We can also use purification tablets to kill germs and clean the water.

We all need clean drinking water to stay healthy.
