Lesson Content

What is Water?

Water is a clear liquid essential for all living things. It is made of two hydrogen atoms and one oxygen atom (H₂O).

Uses of Water

Water is essential for various activities in our daily lives. These include:

Drinking: We drink water to stay hydrated.
Cooking: Water is used in cooking many foods.
Bathing: We use water to clean ourselves.
Washing: We use water to wash clothes and dishes.

Harmful Effects of Water

Unclean water can make us sick.

Water-borne Diseases

Water-borne diseases are illnesses caused by drinking or using contaminated water. These include:

Cholera: A serious illness causing diarrhea.
Typhoid: A bacterial infection affecting the intestines.
Dysentery: An intestinal infection causing diarrhea and stomach cramps.
Hepatitis A: A viral infection affecting the liver.
Polio: A viral disease that can cause paralysis.
Bilharzia (Schistosomiasis): A disease caused by parasitic worms.

Preventing Water-borne Diseases

Preventing water-borne diseases involves measures to ensure water is safe for use. These include:

Boiling Water: Boiling water kills many harmful germs.
Proper Sanitation: Good hygiene, like washing hands, helps prevent disease.
Treating Water: Using water filters or tablets cleans water.
Using Clean Containers: Storing water in clean, covered containers prevents contamination.
Regular Water Testing: Testing water sources regularly helps identify and address contamination issues.
