In this category, we add all the DIY school project models for pre-college students (Class 11 / Grade11 )/ (Class 12 / Grade12 ).
where students can do themselves step by step for their school exhibition or fair
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 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
