How can you make a working model on soil?

To create a working model on soil, you can start by using a clear container to represent soil layers, filling it with different materials like sand, silt, and clay to demonstrate soil composition. Include plants to show how soil supports growth and water retention, or create a water drainage system to illustrate how soil absorbs and holds water. You can also add small rocks or organic matter to highlight soil biodiversity and its importance in ecosystems. Finally, label each layer and component to enhance understanding.
