Purification Of Water (Primary 3)

Hi there, young learners of Primary 3! Welcome back to our Basic science Class! In our previous lesson, we learned about contaminated water. Today, we’re going to learn about purification of water.

Objectives

By the end of this lesson, you should be able to:

• List at least three methods of purifying water.
• Explain the importance of drinking clean water.
• Demonstrate how to use a simple water filter.

Purification of Water

Clean water is vital for our health. There are different methods to purify water to make it safe for drinking. Some of which includes:

1. Boiling: Boil water for at least one minute to kill harmful germs.
2. Filtration: Use a water filter to remove particles and some microorganisms.
3. Chlorination: Add chlorine tablets to water to kill bacteria and viruses.
4. Distillation: Heat water to create steam and then condense it back into liquid to remove impurities.
5. Using UV Light: Use ultraviolet light to destroy bacteria and viruses.

Each of the following method helps ensure the water we drink is safe and clean.

Importance of Drinking Clean Water

Drinking clean water is vital for the following reasons:

1. Prevents Diseases: Clean water helps prevent waterborne diseases such as cholera, dysentery, and typhoid, which can be life-threatening.
2. Supports Body Functions: Water is crucial for digestion, circulation, temperature regulation, and other bodily functions. Clean water ensures these processes occur smoothly without introducing harmful substances.
3. Boosts Immune System: Clean water helps maintain a healthy immune system, enabling the body to fight off infections more effectively.
4. Promotes Overall Well-being: Staying hydrated with clean water improves energy levels, mental clarity, and physical performance.

Ensuring that the water we drink is purified is essential for maintaining good health and preventing illnesses.

Evaluation Questions
