Introduction Energy is the lifeline of modern society. From switching on a light bulb to running industries, we depend on a continuous flow of electricity. But the way we produce energy today is damaging our planet. Burning fossil fuels such as coal, oil, and gas has led to global warming, air pollution, and depletion of … Read more
Introduction The world today faces two big challenges: energy shortage and environmental pollution. Traditional energy sources such as coal, oil, and natural gas are limited and release harmful gases when burned. This is why scientists and engineers are working on regenerative energy systems – systems that can reuse, recycle, or regenerate energy instead of wasting … Read more
Introduction Our planet is facing serious energy challenges. The overuse of fossil fuels such as coal, oil, and natural gas has led to pollution, climate change, and depletion of natural resources. Students, teachers, and scientists are now focusing on “planet-safe” or eco-friendly energy sources that do not harm the environment. Working models of such energy … Read more

Solar Power: Energy from the Sun Solar power means using sunlight to make electricity. This is done with solar panels, which catch the sun’s rays and change them into power. The best thing about solar energy is that the sun never runs out. It is free and clean, unlike coal or oil, which cause pollution. … Read more
Introduction The electric bell is a practical device based on the principle of electromagnetism and mechanical motion. In this DIY version, we replace the traditional coil-striker system with a DC motor-driven striker. The motor rotates, and a fixed striker repeatedly hits a steel glass, producing a ringing sound. This version is simple, cost-effective, and highly … Read more
Introduction In our daily life, we often face situations where tea, coffee, or hot water is too hot to drink immediately. Waiting for it to cool naturally takes time, and using refrigeration or ice may alter taste or waste energy. Farmers, workers, and students need a simple, portable, low-cost solution to cool hot liquids quickly … Read more
Introduction Traffic lights are one of the most important inventions in road safety. They control the flow of vehicles and pedestrians at intersections. The standard traffic signal has three colors: To explain this concept in a science exhibition, you can make a working traffic light model using LED lights, switches, and a battery. This model … Read more
Pythagorean Theorem Working Model – Science Exhibition Introduction The Pythagorean Theorem is one of the most important concepts in mathematics and geometry. It states that: a2+b2=c2 a^2 + b^2 = c^2 a2+b2=c2 Here, a and b are the lengths of the two perpendicular sides of a right-angled triangle, and c is the hypotenuse (the side … Read more
Introduction DNA, or Deoxyribonucleic Acid, is the genetic material that carries instructions for the growth, development, and functioning of all living organisms. Its structure is a double helix – like a twisted ladder – made of sugar-phosphate backbones and base pairs (Adenine-Thymine and Guanine-Cytosine). To showcase this fascinating structure in a science exhibition, you can … Read more
Introduction The Water Cycle (also called the Hydrological Cycle) is the continuous process by which water moves through the Earth’s surface, atmosphere, and underground layers. It involves four main stages: Evaporation, Condensation, Precipitation, and Collection. To make this concept visually engaging, we can create a circular-shaped working model that uses a transparent sheet for rotation … Read more
Introduction Water is one of the most vital resources on Earth, but water pollution is a major global challenge. Untreated wastewater contains dirt, sediments, chemicals, and harmful microorganisms that are unsafe for consumption or irrigation. To address this, wastewater purification systems are used to remove impurities and make water usable. This project demonstrates a DIY … Read more
Introduction During rainfall, clothes left to dry on rooftops often get wet, causing inconvenience and extra effort. To solve this problem, this project demonstrates a Rain Cloth Collector Working Model that automatically moves a shade or roof panel to protect the cloth using blades as sensors and robo motors for movement. This model is innovative, … Read more
