LEARNING OBJECTIVES 

By the end of the lesson, pupils should be able to:

1. Define an inclined plane.

2. Identify examples of inclined planes.

3. State the advantages of an inclined plane.

4. Explain the uses of an inclined plane.

9. Construct a simple inclined plane using available materials.

ENTRY BEHAVIOUR

Pupils have previously learned that simple machines make work easier. They also learned about levers and pulleys, which help people lift and move heavy objects.

This lesson builds on that knowledge by introducing another simple machine called the inclined plane. Pupils will learn how a sloping surface helps people move heavy objects from one level to another with less effort.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Wooden board or cardboard

2. Books or blocks

3. Toy car

4. Small box

5. Ramp

6. Staircase

7. Pictures of ramps and slides

8. Charts showing inclined planes

9. Textbooks

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

Have you ever seen a wheelchair being pushed up a ramp or a wheelbarrow being pushed up a sloping path? Have you walked up a staircase instead of climbing straight up? These are examples of an inclined plane.

An inclined plane is a sloping surface that helps people move heavy objects from one place to another with less effort. It is one of the six basic simple machines and is used in homes, schools, hospitals, markets, and construction sites.

In this lesson, pupils will learn the meaning of an inclined plane, examples, advantages, and how to make a simple inclined plane using everyday materials.

LESSON 1 – MEANING OF AN INCLINED PLANE

An inclined plane is a sloping or slanting surface that helps people move heavy objects from one level to another with less effort.

It is one of the six basic simple machines.

Examples of an Inclined Plane

1. Ramp

2. Staircase

3. Slide in a playground

4. Sloping road

5. Loading ramp for trucks

6. Wheelchair ramp

ADVANTAGES OF AN INCLINED PLANE

1. It makes work easier.

2. It reduces the effort needed to move heavy objects.

3. It helps move loads safely from one level to another.

4. It saves time and energy.

5. It makes it easier for people using wheelchairs to move.

6. It is useful in homes, schools, hospitals, markets, and construction sites.

LESSON 2 – USES OF AN INCLINED PLANE

1. Moving goods into trucks.

2. Helping wheelchair users enter buildings.

3. Walking up staircases.

4. Sliding down playground slides.

5. Moving heavy loads to higher places.

LESSON 3 – HOW TO MAKE AN INCLINED PLANE

Materials Needed:

• A wooden board or thick cardboard

• Two or three books or blocks

• A toy car or small box

Procedure

1. Place the books or blocks on a flat table.

2. Lean one end of the wooden board or cardboard on the books.

3. Leave the other end resting on the table or floor.

4. Place the toy car or small box at the lower end of the board.

5. Push the toy car or box gently up the sloping board.

6. Observe how the object moves up the slope with less effort.

Observation:

• The sloping board forms an inclined plane.

• It is easier to push the object up the slope than to lift it straight up.

Conclusion: An inclined plane is a simple machine that makes it easier to move heavy objects from one level to another by using a sloping surface. It reduces the effort needed to do work.

Safety Precautions

1. Use light objects during the activity.

2. Place the inclined plane on a stable surface.

3. Do not push objects too fast.

4. Keep the activity area clean and free from obstacles.

5. Work under the teacher’s supervision.

SUMMARY

In this lesson, pupils learned that an inclined plane is a sloping surface that helps people move heavy objects from one level to another with less effort. They learned that an inclined plane is one of the six basic simple machines.

Pupils identified common examples of inclined planes, including ramps, staircases, slides, sloping roads, loading ramps, and wheelchair ramps.

They also learned the advantages of an inclined plane, such as making work easier, reducing effort, saving time and energy, helping people move heavy loads safely, and making buildings more accessible for wheelchair users.

Finally, pupils learned how to make a simple inclined plane by placing one end of a wooden board or cardboard on books or blocks to form a sloping surface. They observed that it is easier to push an object up the slope than to lift it straight up.
