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

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

A reflex action working model demonstrates the rapid and automatic response of the body to certain stimuli without conscious thought. Reflex actions are controlled by the nervous system, particularly the spinal cord, bypassing the brain to save time during emergencies. This ensures quick reactions, which are crucial for safety and survival. How the Model Works: … Read more
A microscope working model using cardboard, LED light, and a transparent sheet can simulate the basic functioning of a microscope by demonstrating how light is focused through a lens to magnify objects. The model helps explain the principles behind how a microscope magnifies tiny details by using simple materials to mimic the essential components. Key … Read more
A plant life cycle working model demonstrates the stages a plant goes through from seed to mature plant. It shows the process of how plants grow, reproduce, and complete their life cycle. This model provides a visual representation of the stages of development, from germination to flowering and seed production. Key Components of the Model: … Read more
A heart working model using a plastic bottle, straw pipes, and a balloon demonstrates how the human heart pumps blood through the circulatory system. This model simulates the heart’s pumping action and the flow of blood through the chambers, using basic materials to visualize how the heart functions. Key Components of the Model: How It … Read more
A heart working model using two plastic bottles demonstrates the process of blood circulation in the human heart, including the movement of oxygenated and deoxygenated blood between the heart, lungs, and the body. The two bottles represent the two sides of the heart: one for the right side (pumping deoxygenated blood to the lungs) and … Read more
A DNA working model demonstrates the structure of DNA (Deoxyribonucleic Acid), the molecule that carries the genetic instructions for all living organisms. It showcases the double helix structure and how the base pairs align to encode genetic information. Key Components of the Model: How It Works(dna working model): Purpose and Applications: This simple yet effective … Read more
