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
Introduction During rainfall, clothes left outside often get wet, leading to inconvenience and wastage of time. A Rain Alarm Working Model helps detect rain and automatically moves the cloth or shade to prevent it from getting wet. This project combines mechanical motion, sensors, and electrical circuits to create a practical, low-cost, and interactive solution, making … Read more
Introduction Motion is a fundamental concept in physics that describes how objects change their position over time. Understanding different types of motion is essential in explaining real-world phenomena. This project demonstrates rotational motion, circular motion, oscillatory motion, and periodic motion using simple DIY setups, making it ideal for a science exhibition. Types of Motion Demonstrated … Read more
Introduction Linear equations are the foundation of algebra and mathematics, representing relationships between two variables. In a linear equation of the form y = mx + c, ‘m’ is the slope, and ‘c’ is the y-intercept. To make this concept visually engaging, we can create a working model using LED lights to show the solution … Read more
Introduction DNA, or Deoxyribonucleic Acid, is the molecule that carries the genetic information of all living organisms. It is structured like a double helix – two twisted strands connected by base pairs (A-T and G-C). For science exhibitions, creating a rotating DNA working model helps students visualize its structure and importance in heredity, cell functions, … Read more
Introduction The Bohr Atomic Model, proposed by Danish physicist Niels Bohr in 1913, explains the structure of an atom in a simple way. According to this model, an atom has a positively charged nucleus at the center, and electrons revolve around it in fixed circular orbits, similar to how planets orbit the Sun. This DIY … Read more
Air pollution is one of the most dangerous environmental problems in the modern world. Smoke from factories, vehicles, apartments, and houses fills the air with harmful particles and gases like carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO₂), and fine dust. This reduces air quality, harms human health, damages crops, and contributes to global … Read more
An atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. This model will use plastic balls, GI metal wire, LED lights, and a battery to represent these particles. Materials Required Step-by-Step Construction 1. Base Preparation 2. Nucleus (Center of Atom) 3. Electron Orbits 4. Electrons 5. Electrical Circuit 6. Finishing https://www.youtube.com/@howtofunda
Introduction Waste management is one of the greatest challenges of our time. With increasing urbanization and population, the amount of waste generated daily has risen drastically. If not managed properly, waste leads to pollution, health hazards, and environmental degradation. The solution lies in segregating waste, recycling materials, generating energy, and disposing non-recyclables safely. This working … Read more
Introduction Waste management has become one of the most urgent issues of modern life. To build a clean and healthy environment, waste must be segregated at the source. In India and many other countries, the government has introduced a 4-color dustbin system for easy segregation: This project creates a working model of four dustbins using … Read more
Agriculture has always been the backbone of human civilization. Farmers work tirelessly to grow crops that sustain life, yet they often face challenges that reduce their productivity and profits. In rural India, where most farmers still depend on traditional practices, even small improvements and low-cost innovations can create a huge impact. The two problems that … Read more
