This 3D model of a hibiscus flower is designed to demonstrate the structure and parts of a complete flower. Made using cardboard, tissue paper, fevicol, and paint, it creatively represents essential parts like petals, sepals, stamen, pistil (stigma, style, ovary), and leaves. The model helps students visually understand the reproductive system of flowering plants. Each … Read more
This is a rotating wheel model showing the seed germination cycle.As we rotate the top wheel, we can see the different stages in the life of a plant — from a seed, to germinating seed, then a seedling, followed by a young plant, and finally a mature plant that produces seeds again. This cycle shows … Read more
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
Photosynthesis is the process by which green plants make their own food using sunlight, water, and carbon dioxide. It is one of the most important natural processes on Earth because it provides food and oxygen for all living beings. In photosynthesis, plants take carbon dioxide from the air and water from the soil. The chlorophyll … Read more
This is a Kidney Working Model. The syringe represents the kidney, and the sponge or cotton acts like the nephrons which filter blood. When ‘blood’ (colored water) is pushed through the syringe, the cotton filters it and sends the clean fluid or ‘urine’ into the plastic tray, which represents the bladder. This demonstrates how our … Read more
