Lesson Note On Conversion Of Energy For Primary 3

• Class: Primary 3

• Term: 3rd Term

• Week: 3&4

• Age: 8 years

• Duration: 40 minutes

• Subject: Basic Science & Technology

• Curriculum Theme: Basic Technology

• Previous Lesson: Properties of Energy

• Topic: Conversion of Energy

• Content: From one form to another: electrical energy to heat energy e.g., pressing iron.

Performance Objectives:

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

• Cognitive Domain: Explain the concept of energy conversion and identify examples where electrical energy is converted to heat energy.
• Affective Domain: Show curiosity and interest in how everyday objects convert energy.
• Psychomotor Domain: Demonstrate the basic principle of energy conversion using simple classroom materials.
• Social Domain: Collaborate with peers in group activities to discuss examples of energy conversion in their environment.

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 Energy Conversion Basics

Instructional Materials:

The teacher will teach this lesson with the aid of:

• Diagrams of energy conversion processes
• Real-life objects that involve energy conversion, like a toy electric car
• Videos demonstrating energy conversion
• Flip charts

Rationale for the Lesson:

Understanding energy conversion is essential as it connects to many aspects of daily life, from household appliances to the broader environment, enhancing pupils’ appreciation of how the world operates and encouraging responsible energy use.

Prerequisite/Previous Knowledge:

Pupils are expected to know basic forms of energy as discussed in the previous lesson on Properties of Energy.

Instructional Procedures:

Classroom Note:

Conversion Of Energy

One of the properties of energy is that “energy cannot be created nor destroyed but can only be converted from one form to another”, this statement is called the law of conservation of energy. Therefore, conversion of energy means that energy can change from one form to another. For example:

1. Electric Iron: Converts electrical energy into heat energy to iron clothes.
2. Toaster: Turns electrical energy into heat to toast bread.
3. Electric Car: Changes electrical energy into mechanical energy to move.
4. Flashlight: Converts chemical energy from batteries into light energy.
5. Hair Dryer: Transforms electrical energy into heat and kinetic energy to dry hair.
6. Burning wood: converts chemical energy to heat and light
7. Petrol Generator: Converts chemical energy to mechanical energy then to electrical energy.

Lesson Evaluation:

To evaluate the learning, the teacher asks pupils to:

1. Name two appliances at home that convert electrical energy into heat energy.
2. Explain what happens when you turn on a flashlight.
3. Describe how a toaster works using the concept of energy conversion.

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!
