1. BEHAVIOURAL OBJECTIVES

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

1. Define the Internet of Things (IoT).
2. Identify the major components of an IoT system.
3. Explain how connected devices collect and exchange data.
4. Describe applications of IoT in smart homes, smart cities, agriculture, healthcare and industries.
5. State the advantages and challenges of IoT technology.
6. Identify safety measures for protecting connected devices and data.

2. INSTRUCTIONAL / TEACHING AIDS

• Computer system or laptop.
• Smartphone and internet connection, where available.
• Pictures or charts of smart devices, sensors and connected systems.
• Projector or display screen, where available.
• Whiteboard and markers.
• Examples of connected devices, such as a smart watch, security camera or smart bulb, where available.

3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students have learned about computer networks, the internet and cloud computing. They may have used smartphones, online applications or devices that connect to a network.

Entry questions:

1. What is a computer network?
2. Can you name any device other than a computer that can connect to the internet?
3. How can a smartphone receive an alert from a security camera located elsewhere?

4. PRESENTATION STEPS

STEP	TEACHER'S ACTIVITY	STUDENTS' ACTIVITY
Step 1: Introduction 10 minutes	Reviews previous lessons on networking and cloud computing. Shows or describes connected devices and introduces the meaning of IoT.	Mention connected devices they know and explain how such devices may be useful.
Step 2: Components of IoT 15 minutes	Explains sensors, connectivity, processors or controllers, software, actuators and power supplies. Gives practical examples of each component.	Identify the components and state their functions. Give examples of sensors and actuators.
Step 3: How IoT Works 10 minutes	Explains data collection, transmission, processing, decision-making and action using a smart irrigation system as an example.	Describe how a connected device can collect data and respond automatically to a condition.
Step 4: Applications of IoT 20 minutes	Discusses IoT applications in smart homes, smart cities, agriculture, healthcare, manufacturing and transport.	Identify applications in each area and explain their benefits using examples.
Step 5: Benefits and Challenges 10 minutes	Explains automation, remote monitoring and efficiency. Discusses security, privacy, cost, compatibility and connectivity challenges.	List the advantages and challenges of IoT and suggest ways to reduce security risks.
Step 6: Evaluation and Conclusion 15 minutes	Asks oral and written questions, corrects misconceptions and summarises the main points. Gives students an assignment.	Answer evaluation questions, participate in the discussion and record the assignment.

5. EVALUATION QUESTIONS

1. What is the Internet of Things (IoT)?
2. State five components commonly found in an IoT system.
3. Differentiate between a sensor and an actuator.
4. Explain how a smart irrigation system works.
5. State three applications of IoT in smart homes and smart cities.
6. Explain three uses of IoT in agriculture, healthcare or industry.
7. State four benefits and four challenges of IoT.
8. List five safety measures for protecting connected devices.

6. ASSIGNMENT

1. Define IoT and describe five examples of connected devices.
2. Explain four ways IoT can be used in agriculture, healthcare or industry.
3. State three advantages and three disadvantages of IoT.
4. Design a simple IoT system for your school. State its purpose, components, data collected and expected benefits.
5. List five precautions users should take to protect connected devices from unauthorised access.

7. TEACHER'S REFLECTION

After the lesson, the teacher should reflect on the following:

• Were students able to define IoT and identify its components?
• Could students explain how connected devices collect and exchange data?
• Did students identify relevant applications of IoT in their community?
• Which areas require further explanation or practical demonstration?
• What improvements should be made in the next lesson?
