This model shows how rainwater can be collected from rooftops, passed through a homemade filter using a syringe, and stored in a ground tank.It can then be used for daily household needs or watering plants, saving water and promoting sustainability. This setup is low-cost and effective for rural as well as urban areas. Video Construction … Read more
This 3D model demonstrates both Solar and Lunar Eclipses.The Sun, Earth, and Moon are represented by these three colored balls.In a Solar Eclipse, the Moon blocks the Sun’s light and casts a shadow on Earth.In a Lunar Eclipse, the Earth comes between the Sun and Moon, casting a shadow on the Moon.This model helps us … Read more
This is a 3D atom model showing its internal structure.The center or nucleus contains protons and neutrons, while electrons revolve around it in orbits. Each component is represented with colored balls and glowing LEDs, controlled using switches.This model demonstrates how atoms are structured and the role of subatomic particles. Video Construction Steps: Step 1: Prepare … Read more
“This is a working model of a Geothermal Energy Power Plant.Water is pumped underground where Earth’s heat turns it into steam.This steam rises through pipes, rotates a turbine, and generates electricity.The electricity is transmitted through power lines to homes and factories. Geothermal energy is a renewable, clean, and sustainable power source.” Video Step-by-Step Model Instructions: … Read more
“This is a hydroelectric power generation model.Water stored in the dam flows through a pipe and hits the turbine. The turbine spins a generator (DC motor), which produces electricity.This electricity is carried through transmission lines supported by power poles to homes, factories, and cities.Hydroelectricity is a clean, renewable source of energy. Concept Explanation: Hydroelectricity is … Read more
“This is a combined renewable energy model. On the left, hydroelectric power is generated when water flows and turns the turbine. In the middle, wind energy converts kinetic energy of air into electricity. On the right, solar energy is captured by solar panels to power homes.All these sources are eco-friendly, renewable, and sustainable. Here’s a … Read more
This is a working model that shows how parallel lines and a transversal form different types of angles. When I turn on the switch, the LEDs highlight matching angle pairs.For example, corresponding angles lie on the same side of the transversal and in matching corners. Alternate interior angles lie inside the lines and on opposite … Read more
“This is a 3D model of the Periodic Table, made using cardboard and colored paper. Each tile represents one element, showing its atomic number, symbol, and category. The color coding helps you quickly identify metals, non-metals, gases, metalloids, and more. The 3D elevation makes it easier to see the element blocks and groups. How to … Read more
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 model shows how the Earth rotates on its axis, causing day and night. The Sun remains stationary and glows using an LED. The Earth rotates using a slow motor, and as it turns, different parts face the Sun or move into shadow. This helps us understand the real reason for day and night on … Read more
This is an interactive 3D shapes teaching model with rotating wheels. As you spin the wheel, you can see the volume, surface area, faces, edges, and vertices of each shape. This helps students quickly revise and understand geometry concepts through fun learning. Each wheel also shows a real-world example, like a dice for cube or … Read more
This project demonstrates how 3D geometric shapes are used in real-life buildings and structures. Every building in this model is based on a different 3D shape like cubes, cuboids, cylinders, cones, spheres, pyramids, and prisms. This helps students understand geometry through real-world applications like homes, towers, domes, lighthouses, etc. How to Build the 3d Shapes … 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
