THEME – UNDERSTANDING BASIC TECHNOLOGY 

PREVIOUS LESSON – Meaning of Drawing Instruments | Uses of Drawing Instruments (Basic Preparation) Primary 5 (Basic 5) – Basic Technology

 

TOPIC – MEANING AND IMPORTANCE OF ENERGY CONVERSION 

 

LEARNING AREA

1. Introductory Activities

2. Meaning and Forms of Energy Conversion

3. Importance of Energy Conversion

4. Importance of Energy Conversion

5. Lesson Evaluation and Weekly Assessment

 

PERFORMANCE OBJECTIVES 

By the end of the lesson, most of the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. explain the meaning of energy conversion.

2. name forms of energy conversions.

3. state the importance of energy conversions.

 

RATIONALE

Energy is the fundamental need of our everyday life. So much so, that the quality of life and even its sustenance, is dependent on the availability of energy. The Law of conservation of energy even tells us that the only thing that takes place with energy is the transformation from one form to another.

The concept of energy conservation will enable the pupils to understand and appreciate the importance of energy conservation in our daily lives.

 

ENTRY BEHAVIOUR

The pupils can power a bulb with electricity and also power the same bulb with batteries.

 

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Electric pressing iron

2. Immersion heater (boiling ring)

 

 

3. Kerosene Stove.

4. Charcoal Pressing iron

5. Bicycle Dynamo

 

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. 

 

REFERENCE MATERIALS

1. Scheme of Work

2. 9 – Years Basic Education Curriculum

3. Course Book

4. All Relevant Material

5. Online Information

WRITING INSTRUCTION 

Copy as I write or draw as I write. This instruction should be given when you need the pupils to write or draw.

 

CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTORY ACTIVITIES 

Teacher’s Activities – Ask the pupils,

1. Rub your palms together gently and very fast. What do you notice?

2. What do you feel when you are standing under the sun for too long?

3. What other things produce the same amount or more of what you notice when you rub your palms together?

 

 

Pupil’s Activities – Our palms get warm (hot). The body will get warm (feel heat). Stove, pressing iron, boiling ring, sun, etc.

Teacher’s Remark – There are form of energy. Heat energy is one of them. Other energy are light energy, mechanical energy, solar energy (energy from the sun), etc. Lead the pupils to discuss energy conversion, list and demonstrate how one energy changes to another. Note all points on the board for writing.

 

MEANING OF ENERGY CONVERSION 

Energy conversion is the changing of one form of energy to another.

 

FORM OF ENERGY

1. Heat energy

2. Electrical energy

3. Mechanical energy

4. Solar energy

5. Chemical energy

6. Sound energy

7. Light energy

 

FORMS OF ENERGY CONVERSIONS

The forms of energy are electrical energy, heat energy, chemical energy and mechanical energy. These energy can change form to another energy and vice versa as listed below:

 

 

1. Mechanical energy can be converted to heat energy.

 

2. Electrical energy can be converted to heat energy.

For example, pressing iron, electric stove, etc.

 

3. Electrical energy can be converted to mechanical energy.

For example, blender, electric cooker, etc.

 

4. Mechanical energy can be converted to electrical energy.

For example, generator

 

5. Chemical energy can be converted to heat energy.

For example, kerosene stove, etc.

 

6. Solar energy can be converted to heat energy, chemical energy, and electrical energy.

 

7. Light energy can be converted to heat energy.

 

QUICK EVALUATION 

1. What is energy conversion?

2. State 5 form energy.

3. Discuss and demonstrate how one energy is converted to another.

 

ASSIGNMENT 

Find out 5 importance of energy.

 

LESSON 2 – INTRODUCTORY ACTIVITIES 

Teacher’s Activities – Use different form energy to lead the pupils to state the importance of energy.

 

 

Pupil’s Activities – Follow the teacher’s lead to state the importance of energy.

Teacher’s Remark – Support each point mentioned by the pupils with more examples and comments. Note all points on the board for writing.

 

IMPORTANCE OF ENERGY CONVERSIONS 

The most important of energy is that it can change form. For example,

1. It saves money.

For example, the use of battery, inverter and solar energy.

 

2. It reduces pollution.

For example, the use of kerosene stove, electric cooker and gas cooker.

 

3. It saves energy.

For example, battery, solar battery, etc.

 

4. It generates energy.

For energy, solar battery, generator, etc.

 

5. It replaces non renewable energy.

 

LESSON 3 – REVISION AND WEEKLY ASSIGNMENT 

As stated in performance objectives or lesson evaluation. 

 

ASSIGNMENT

Find out the different between heat and temperature.

 

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;

2. Discusses the meaning of energy conversion.

Pupil’s Activities – Participate in class discussion.

3. Demonstrates the conversion of energy from one form to another.

 

 

Pupil’s Activities – Carry out simple activities on energy conversion.

4. Discusses the importance of energy conversions.

Pupil’s Activities – List the forms and importance of energy Conversion.

5. Summarizes the lesson on the board.

Pupil’s Activities – Copy as the teacher writes.

 

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
