This is a 3D model of an animal cell using a quarter-cut plastic ball to show the inside. Each organelle is placed in its correct position. The nucleus controls the cell, mitochondria generate energy, the ER transports materials, and the Golgi body packages them. The cytoplasm fills the space, and the cell membrane controls what … Read more
This is a working 3D model of the human hand using hinge joints. Each finger is made of 3 bones (phalanges) connected by hinge joints, allowing them to bend in one direction. The thread works like tendons that pull the bones, simulating how our real muscles move fingers. This model shows how ligaments and muscles … Read more
Concept Overview: How to Make the 3d Heart Working Model: 1. Build the Heart Structure (3D Look): 2. Create the Circulatory Flow: 3. Syringe Movement Mechanism: 4. Add Final Touches:
This working model shows how food moves through the human digestive system using peristalsis. Each syringe represents muscle movement that pushes food from one organ to another. Starting from the mouth, food travels through the esophagus to the stomach, then into the intestines where digestion and absorption take place. Finally, waste is expelled through the … Read more
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
This model explains the process of photosynthesis—how plants make their food using sunlight, carbon dioxide, water, and chlorophyll. The model will have: Materials Required: Video Step-by-Step Instructions: 1. Make the Rotatable Base: 2. Create the Plant: 3. Setup the LED Sun: 4. Add Labeled Parts: 5. Add Rotating Mechanism: https://www.youtube.com/@howtofunda
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
In this DIY video, learn how to make a Balanced Diet Wheel Working Model using cardboard, color paper, and a rotating pointer. This simple yet educational project helps students understand the different food groups and the importance of a balanced diet in an engaging way. Turn the arrow to any food group and explain the … Read more
For your microscope working model, here’s how you can build it using cardboard, an LED light, a transparent sheet, a cardboard pipe, color paper, and mobile zoom: Materials Needed: Steps to Build: How It Works: https://www.youtube.com/@howtofunda
This model will demonstrate the working of the human heart, focusing on how blood flows through the heart using syringes, paint, cardboard, and aluminum foil. It will show the basic heart structure (atria, ventricles, and valves) and how the pumping action occurs. Materials Required: Cardboard (for heart structure and base)Syringes (for simulating blood flow)Aluminum foil … Read more
