CONTENT OF THE LESSON

INTRODUCTION

Every day, we use different materials and objects such as chairs, tables, books, school bags, bicycles, and household equipment. These items can become dirty, worn out, or damaged if they are not properly cared for.

To keep materials clean, attractive, safe, and useful for a long time, regular maintenance is necessary. Maintenance helps to prevent damage and reduces the cost of repairs and replacement.

In this lesson, pupils will learn the meaning of maintenance, examples of maintenance activities, the need for maintenance, materials used for maintenance, and the advantages of maintaining materials and equipment.

LESSON 1 – MEANING OF MAINTENANCE

Maintenance is the act of taking care of materials, tools, equipment, and property to keep them clean, safe, and in good working condition.

Examples of Maintenance

• Sweeping the classroom and surroundings.

• Washing school uniforms and other items.

• Dusting furniture and equipment.

• Painting walls, doors, and windows.

• Oiling moving parts of machines and bicycles.

• Repairing damaged chairs, tables, and tools.

• Cleaning electrical appliances and equipment.

• Replacing worn-out parts of machines and tools.

Maintenance is the proper care of materials and equipment to keep them useful and in good condition. Common examples include sweeping, washing, dusting, painting, oiling, and repairing.

NEED FOR MAINTENANCE

Maintenance is important because it helps to keep materials, tools, equipment, and property in good condition. The reasons for maintenance are:

1. To keep materials clean and neat.

2. To prevent damage and deterioration.

3. To improve safety when using materials and equipment.

4. To make materials and equipment last longer.

5. To reduce the cost of repairs and replacement.

6. To ensure proper functioning of tools and machines.

7. To improve the appearance of materials and property.

8. To prevent waste of resources.

Maintenance is necessary because it keeps materials clean, safe, attractive, and functional. It also helps to prevent damage, save money, and increase the lifespan of materials and equipment.

LESSON 2 – MATERIALS NEEDED FOR MAINTENANCE

1. Broom – used for sweeping floors and surroundings.

2. Brush – used for scrubbing and cleaning surfaces.

3. Soap – used for washing and removing dirt.

4. Water – used for cleaning and washing.

7. Paint – used for protecting and beautifying surfaces.

8. Lubricating Oil – used for oiling moving parts of machines and tools.

9. Detergent – used for washing clothes and cleaning materials.

10. Screwdriver and Hammer – used for simple repairs.

Maintenance materials are items used to care for and protect materials and equipment. Examples include brooms, brushes, soap, water, cloths, paint, lubricating oil, and repair tools.

LESSON 3 – ADVANTAGES OF MAINTENANCE

Maintenance provides many benefits for materials, tools, equipment, and property:

1. It increases the lifespan of materials and equipment.

2. It reduces the cost of repairs and replacement.

3. It keeps materials clean and attractive.

4. It improves safety during use.
