This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more
This is my working model on Rainwater Harvesting and Water Purification. When it rains, water falls on the rooftop of the house. This water is collected through pipes and directed into a storage tank. The collected rainwater may contain dirt and impurities, so it is sent through a 5-step filtration system: After this process, the … Read more
This is working model on Photosynthesis, the process by which green plants make their own food using sunlight, water, and carbon dioxide. As you can see, the LED light represents sunlight, which helps the leaves carry out photosynthesis. Water is absorbed from the soil through the roots, and carbon dioxide from the air enters the … Read more
