How do you make a working model of waste management for class 9?

To create a working model of waste management for class 9, start by researching the waste management process, including waste segregation, recycling, composting, and disposal. Use materials like cardboard, plastic containers, and colored paper to represent different waste categories (e.g., organic, recyclable, and landfill). You can create compartments in a box to demonstrate waste segregation and use simple mechanisms, like a lever or pulley, to show how waste is collected and processed. Finally, label each part clearly and provide explanations on how effective waste management contributes to a cleaner environment.
