Objective: By the end of the lesson, Grade 5 students will be able to identify and differentiate between useful and harmful materials found in their surroundings, understand their impact on the environment and human health, and make informed decisions about their usage.

Subject Matter: Useful and Harmful Materials Everywhere

Materials: - Whiteboard or blackboard - Markers or chalk - Chart paper - Pictures or samples of various materials (e.g., plastic, glass, paper, metal, chemicals) - Video resources (links provided below) - Worksheet resources (links provided below)

Value Focus: Environmental awareness, responsible decision-making, critical thinking

Integration: Science, Environmental Studies, Health Education

Drill: Ask students to name different materials they encounter in their daily lives. Write their responses on the board.

Review: Recall the previous lesson on the importance of reducing, reusing, and recycling materials. Discuss the concept of waste management and its impact on the environment.

Motivation: Show a short video clip highlighting the consequences of using harmful materials and the benefits of using useful materials. For example, you can use the following video: “Useful and Harmful Materials” (https://www.youtube.com/watch?v=12345).

Presentation: 1. Introduce the topic by explaining that materials are all around us, and they can be classified as either useful or harmful. 2. Display pictures or samples of various materials and ask students to categorize them as useful or harmful. 3. Discuss the characteristics and properties of each material, emphasizing their benefits and drawbacks. 4. Explain the impact of harmful materials on the environment and human health, such as pollution, global warming, and diseases. 5. Highlight the importance of using useful materials wisely and responsibly.

Discussion: Engage students in a discussion by asking the following questions: - Can you think of any examples of useful materials that are harmful when not used properly? - How can we reduce the usage of harmful materials in our daily lives? - What are some alternatives to harmful materials that we can use?

Exercises: 1. Divide the class into small groups and provide each group with a worksheet to complete. Here are some worksheet resources: - “Useful or Harmful?” worksheet (https://www.teachstarter.com/us/teaching-resource/useful-or-harmful-worksheet/) - “Materials Around Us” worksheet (https://www.education.com/download/worksheet/105682/materials-around-us.pdf) 2. After completing the worksheets, have each group present their findings to the class.

Generalization Question: Ask students to summarize the main differences between useful and harmful materials and explain why it is important to use materials responsibly.

Application: In pairs or small groups, ask students to conduct a mini-research project on a specific material (e.g., plastic, paper, metal) and create a presentation highlighting its uses, benefits, drawbacks, and eco-friendly alternatives.

Evaluation: Assess students’ understanding through class participation, worksheet completion, and their ability to present their research findings effectively.

Assignment: As a follow-up assignment, ask students to create a poster or infographic illustrating the importance of using useful materials and the consequences of using harmful materials. They can use the information gathered during the lesson and their research project.
