1. BEHAVIOURAL OBJECTIVES

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

1. Define computer waste management and electronic waste (e-waste).
2. Identify common examples of computer and electronic waste.
3. Explain the dangers of improper e-waste disposal.
4. Describe safe methods of disposing of unwanted electronic equipment.
5. Explain the meaning and importance of recycling electronic waste.
6. Describe the basic stages of electronic waste recycling.
7. Explain the 3Rs of waste management: Reduce, Reuse and Recycle.

2. INSTRUCTIONAL / TEACHING AIDS

• Pictures of old computers, monitors, keyboards, printers and mobile phones.
• Chart showing examples of electronic waste.
• Chart illustrating Reduce, Reuse and Recycle.
• Whiteboard and markers.
• Computer components or accessories that are safe to demonstrate.
• Pictures or diagrams showing electronic waste collection and recycling.

3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students are familiar with computers, mobile phones and other electronic devices. They may have seen damaged or outdated electronic equipment at home, in school or in offices.

Teacher's entry questions:

1. What happens when a computer or phone stops working?
2. Have you seen old or damaged electronic devices thrown away?
3. Why should we avoid throwing rubbish into drains or burning it indiscriminately?

The teacher uses students' responses to introduce computer waste management and the need for safe disposal and recycling.

4. PRESENTATION STEPS

STEP / TIME	TEACHER'S ACTIVITY	STUDENTS' ACTIVITY
Step 1: Introduction 5 minutes	The teacher asks students what happens to damaged or unwanted electronic devices and introduces the topic, Computer Waste Management.	Students share their experiences with old or damaged computers and other electronic devices.
Step 2: Meaning and Examples of E-Waste 12 minutes	The teacher defines computer waste management and e-waste. The teacher explains examples such as damaged computers, monitors, printers, phones, batteries and cables.	Students define e-waste, identify examples and classify items shown in pictures.
Step 3: Dangers of Improper Disposal 10 minutes	The teacher explains environmental pollution, harmful smoke from burning electronics, possible health risks, blocked drainage and the loss of recoverable materials.	Students discuss the effects of dumping or burning electronic waste and suggest safer alternatives.
Step 4: Safe Disposal Methods 15 minutes	The teacher explains suitable collection points, authorised recycling services, repair, responsible donation, safe battery handling and the need to protect personal data before handing over devices.	Students identify safe disposal methods and explain how to handle unwanted electronic equipment responsibly.
Step 5: Recycling Practices 12 minutes	The teacher defines recycling and explains collection, sorting, assessment, safe dismantling by trained personnel, material recovery and appropriate treatment of hazardous components.	Students describe the basic recycling process and state the benefits of recycling electronic waste.
Step 6: The 3Rs 8 minutes	The teacher explains Reduce, Reuse and Recycle and gives computer-related examples of each principle.	Students give examples of how the 3Rs can be applied to computers and electronic accessories.
Step 7: Class Activity and Evaluation 13 minutes	The teacher presents pictures of electronic items and asks groups to suggest safe ways to repair, reuse, recycle or dispose of them. The teacher asks evaluation questions.	Students classify the items, suggest safe management methods and answer the evaluation questions.
Step 8: Summary and Assignment 5 minutes	The teacher summarises the main points, reinforces safety precautions and gives the assignment.	Students state important lessons learned and write down the assignment.

Total Duration: 80 Minutes
