This model demonstrates how wind energy can be converted into electrical energy using a wind turbine connected to a DC motor, which powers an LED bulb to light up a cardboard house. This model shows how wind energy is converted into electrical energy using a wind turbine connected to a DC motor. The electricity powers … Read more

An automatic barrier gate operates using a DC motor and a rotating arm, controlled manually or with sensors. It’s used to restrict or allow vehicle access in areas like parking zones or railway crossings. This model shows how an automatic barrier gate works using a DC motor to control the movement of the gate arm. … Read more

This working model is a Water Fountain, demonstrating how a closed water system uses a pump to circulate water. It also helps explain concepts of pressure, water recycling, and motor-powered flow systems. Such mechanisms are used in gardens, buildings, and artificial water features. This model demonstrates a recycling water fountain using a DC water pump … Read more

This model uses hydraulic pressure to compress a balloon or soft object between two platforms, showing how force applied to a small area can be transferred and multiplied using liquid-filled syringes. This is a Hydraulic Press model. It works on Pascal’s Law, which states that pressure applied to a fluid is transmitted equally in all … Read more

“This model shows the natural Water Cycle that occurs on Earth. Water evaporates from oceans and rivers due to the sun’s heat, condenses to form clouds, then falls as rain or snow (precipitation), and finally collects in rivers, lakes, and oceans. This cycle is essential for life on Earth.” This model creatively demonstrates the four … Read more

This model shows how a motorized elevator (lift) works using simple materials. The cardboard is used to make a multi-story house, and a robo motor + woolen thread is used to raise and lower the lift cabin. Materials Required: Video Step-by-Step Instructions: 1. Make the Building (Lift Shaft): 2. Create the Lift Cabin: 3. Attach … Read more

A soil profile shows the different layers of soil formed over thousands of years. Each layer (called a horizon) has different composition, texture, and function: Materials Needed: Steps to Make the Model: 1. Prepare the Base: 2. Create the Soil Layers (Top to Bottom): 3. Add Details on Surface: 4. Label the Layers: Use small … Read more

This 3D model uses a large Earth ball at the center and showcases 5 key environmental protection themes around it. Each section visually shows what to do vs what not to do to help the Earth.
