• Class: Primary 3
• Term: 3rd Term
• Week: 7
• Age: 9 years
• Duration: 40 minutes
• Subject: Basic Science and Technology
• Curriculum Theme: Basic Technology
• Previous Lesson: Uses of Mechanical Energy
• Topic: Objects That Use Mechanical Energy
• Content: Objects That Use Mechanical Energy

Performance Objectives:

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

• Cognitive Domain: Identify and list at least three objects that use mechanical energy.
• Affective Domain: Express interest and curiosity in learning about mechanical energy.
• Psychomotor Domain: Demonstrate how at least one object that uses mechanical energy works.
• Social Domain: Discuss and share ideas with classmates about the use of mechanical energy in everyday life.

Reference Materials:

The following resources were used in planning this lesson:

• 9 – Years Basic Education Curriculum
• Abuja Educational Resource Centre Scheme of Work
• NAPPS National Unified Scheme of Work
• Online Information from Study.com
• Relevant Textbooks

Instructional Materials:

The teacher will teach this lesson with the aid of:

• Pictures or models of objects that use mechanical energy (e.g., bicycle, windmill, clock, hand drill, sewing machine)
• Whiteboard and markers
• Chart paper and markers
• Videos or animations showing mechanical energy in action (if available)

Rationale for the Lesson:

Understanding objects that use mechanical energy helps pupils appreciate how energy powers many tools and devices they encounter daily. This knowledge fosters an understanding of basic physical principles and encourages curiosity and innovation in using and creating technology.

Prerequisite/Previous Knowledge:

Pupils are expected to have basic knowledge of what mechanical energy is and its general uses from the previous lesson.

INSTRUCTIONAL PROCEDURES

Learning Area: Objects That Use Mechanical Energy

To deliver this lesson, the teacher will adopt the following steps:

Classroom Note:

Objects That Use Mechanical Energy

Mechanical energy is the energy that an object has due to its motion or position. This means that objects can use mechanical energy to do work. Some objects that use mechanical energy are:

1. Bicycle: When you pedal a bicycle, your legs provide mechanical energy to move the bike.
2. Windmill: Wind provides mechanical energy to turn the blades of a windmill.
3. Clock: In mechanical clocks, gears and springs use mechanical energy to keep time.
4. Hand Drill: Turning the handle of a hand drill converts mechanical energy into the motion needed to drill holes.
5. Sewing Machine: Mechanical energy from the foot pedal or electric motor moves the needle up and down.

Lesson Evaluation:

To evaluate the learning, the teacher asks pupils to:

1. List three objects that use mechanical energy.
2. Explain how a bicycle uses mechanical energy.
3. Describe what happens in a windmill when it uses mechanical energy.
4. Demonstrate how to use a hand drill and explain the role of mechanical energy in its operation.
5. Share one new thing they learned about mechanical energy today.

Note for teachers using my lesson plan:

Hi there, remember that I didn’t make this lesson plan with any particular class or teacher in mind and I tried as much as possible with my experience and expertise to deliver this plan in a standard and effective style utilizing the best strategy and methods. Nevertheless, you are free to customize the lesson content, teaching methods, timing, and pupil activities to suit your teaching style, pupils’ comprehension, curriculum, and resources available to you. Happy teaching!
