Term: 2^nd Term

WEEK: 1

Class: Senior Secondary School 3
Age: 17 years
Duration: 40 minutes for each of 5 periods
Date:
Subject: Physics
Topic: Dams and Energy Production
Subtopics:

• Location of dams for producing electricity in Nigeria
• Principle of production of electricity from a dam

SPECIFIC OBJECTIVES:

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

1. Identify key locations of dams in Nigeria that produce electricity.
2. Explain the principle of electricity production from a dam.
3. Understand the process of generating electrical energy through hydroelectric power.

INSTRUCTIONAL TECHNIQUES:

• Explanation
• Discussion
• Demonstration
• Video clips on hydroelectric power generation
• Question and answer

INSTRUCTIONAL MATERIALS:

• Maps of Nigeria with key dams marked
• Charts on the process of hydroelectric power generation
• Videos showing how hydroelectric dams generate electricity
• Physics textbook

INSTRUCTIONAL PROCEDURES

PERIOD 1-5

PRESENTATION
STEP 1: INTRODUCTION

• The teacher will start with a brief discussion on the importance of energy in society.
• The teacher will ask students where they think energy comes from and lead the discussion toward dams as a significant source of electrical energy.

STEP 2: EXPLANATION

• The teacher will explain the concept of hydroelectric power, stating that it is generated by converting the potential energy of water stored in a dam into electrical energy.
• The teacher will also introduce major dams in Nigeria such as the Kainji Dam, Jebba Dam, and Shiroro Dam.

STEP 3: DEMONSTRATION

• The teacher will demonstrate the process of hydroelectric power generation using a simple diagram on the whiteboard.
• The teacher will show a video clip that illustrates the function of a hydroelectric dam.

STEP 4: DISCUSSION

• The teacher will engage the students in a discussion about the advantages of hydroelectric power, such as its renewable nature, and the impact it has on electricity production in Nigeria.

STEP 5: NOTE TAKING

• The teacher will write a summary on the board for the students to copy.

NOTE:

• Hydroelectric Power:
• Principle: Electricity is produced when water stored at a higher altitude in a dam is released, and its potential energy is converted into kinetic energy. This energy is used to turn turbines connected to a generator, producing electricity.
• Major Dams in Nigeria:

1. Kainji Dam
2. Jebba Dam
3. Shiroro Dam
4. Zungeru Dam
5. Afam Power Station

EVALUATION

1. List and describe the role of three major dams in Nigeria that produce electricity.
2. Explain how electricity is produced from a dam.
3. What are the advantages of hydroelectric power?

CLASSWORK:

• Draw a simple diagram showing how a dam generates electricity.
• List five major dams in Nigeria and their locations.

CONCLUSION:

• The teacher will review the answers with the students and provide feedback.

Students will reflect on the importance of dams in energy production, especially in Nigeria.
