Aim / Objective: To demonstrate how dry waste collected from households and streets can be converted into electricity by burning it to produce steam, which drives a turbine-generator. Materials Required: Working Principle: Procedure: Observation: Conclusion: The waste-to-electricity model demonstrates the principle of energy conversion from dry waste to electricity.It highlights the importance of waste management, … Read more

Aim / Objective: To demonstrate how hydraulic pressure can be used to lift a vehicle, showing the application of Pascal’s Law in real-world machinery. Materials Required: Working Principle: The model works on Pascal’s Law, which states that pressure applied to a confined fluid is transmitted equally in all directions. Procedure: Observation: Conclusion: The hydraulic car … Read more

Materials Required: Working Principle: The model works on the principle of hydroelectricity: Procedure: Observation: Conclusion: The model demonstrates the basic working of a hydroelectric power plant on a small scale.It shows how … Read more

Aim / Objective: To demonstrate how wind energy produced by fast-moving vehicles on highways can be captured using a vertical axis wind turbine (VAWT) to generate electricity. Materials Required: Working Principle: This model works on the principle of energy conversion — converting kinetic energy from the air displaced by moving vehicles into mechanical energy of … Read more

Aim / Objective: To demonstrate how wind energy can be converted into electrical energy using a windmill, showing the principle of renewable energy generation. Materials Required: Working Principle: The windmill works on the principle of energy conversion — it converts kinetic energy of wind into mechanical energy, and then into electrical energy.When wind strikes the … Read more

Natural resources are the treasures that nature provides to all living organisms. They include air, water, soil, forests, minerals, fossil fuels, and biodiversity. These resources are the foundation of life on Earth and are essential for survival, development, and progress. Without natural resources, human civilization cannot exist. Natural resources are broadly classified into renewable resources … Read more

1. Introduction Disasters are sudden events that cause large-scale destruction to life, property, and the environment. They may be natural (earthquakes, floods, cyclones) or man-made (fires, accidents, wars, industrial hazards). Disaster Management refers to planning, preparedness, response, and recovery efforts taken to reduce the impact of disasters. It is essential for a safe and sustainable … Read more
