working model of a Geothermal Energy Power Plant

Geothermal energy uses heat from deep inside the Earth. In some places, hot water and steam come from underground. This steam can run turbines to make electricity. It is clean, renewable, and available all year. Countries like Iceland and the USA use geothermal power a lot. It can also be used to heat houses and … Read more

hydroelectricity working model – water energy science project – how it works

Hydropower is energy made from flowing water. When water flows down from a dam, it pushes turbines that create electricity. This energy is renewable, as water keeps flowing in rivers. Hydropower gives steady power day and night, unlike solar or wind which depend on weather. It also helps with irrigation and flood control. But building … Read more

renewable energy working model for science project exhibition – creative and inspire

“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

3D model of the Periodic Table

“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

3D model of an animal cell making using plastic ball

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

3D geometric shapes city model making

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

working 3D model of the human hand using hinge joints

The human hand is one of the most important parts of our body. It helps us hold, grab, write, and do many daily tasks. The hand can move in different ways because it has joints, which are places where bones meet. A hinge joint is a type of joint that works like a door – … Read more
