Introduction Water is one of the most essential resources for life on Earth. It covers about 71% of the Earth’s surface and is vital for drinking, agriculture, industry, and sanitation. Clean water is crucial for maintaining health and ecological balance. However, due to human activities and natural factors, water bodies like rivers, lakes, oceans, and … Read more
Introduction Light is a form of energy that makes vision possible. It is an essential part of our daily life, helping us perceive the world around us. Light travels in straight lines and allows us to see objects, colors, and shapes. It also plays an important role in plant growth, climate, and energy generation. The … Read more
Introduction Electricity is one of the most important discoveries in human history. It is a form of energy that powers homes, industries, schools, and almost every aspect of modern life. Without electricity, we cannot imagine living in today’s world of computers, mobile phones, and electronic devices. Electricity is the flow of electric charge, usually carried … Read more
Introduction The human body is a complex machine that needs energy to function. This energy is derived from the food we eat. However, food cannot be directly used by our body in its original form. It must be broken down into simpler molecules like glucose, amino acids, fatty acids, and glycerol that can be absorbed … Read more
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
This collection of 10 Best Inspire Award 2025 Working Model Ideas focuses on practical, easy-to-build, and eco-friendly solutions using commonly available materials like cardboard, sensors, without sensors, solar panels, small motors, and recyclables.

How It Works – Simple Principle: Basic Idea:Air cooler works by blowing air through a wet surface → Evaporative cooling effect lowers air temperature. 3. Step-by-Step Assembly: Structure … 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
