Introduction In today’s digital age, computers have become an essential part of our everyday life. They are used in schools, offices, hospitals, banks, industries, and homes. Understanding the basic parts of a computer system is very important for students. A computer works on the simple principle of Input – Process – Output. This project is … Read more
Introduction Computers play an important role in our daily life, from education and communication to business and entertainment. Every computer system works on the basic principle of Input – Process – Output (IPO). Input devices are used to give data and instructions to the computer, while output devices are used to display or produce the … Read more
Introduction The kidneys are vital organs of the human body that help in filtering waste products, excess salts, and extra water from the blood. They maintain the balance of electrolytes and help regulate blood pressure. However, when the kidneys fail due to diseases such as diabetes, high blood pressure, infection, or injury, harmful waste starts … Read more
Introduction: Conservation of Energy Energy is the ability to do work or cause change. It exists in many forms such as mechanical energy, heat energy, light energy, electrical energy, and chemical energy. In our daily life, we constantly observe energy changing from one form to another. The Law of Conservation of Energy states that energy … Read more

Introduction Water is one of the most important natural resources on Earth. All living organisms—humans, animals, and plants—depend on water for survival. However, in many parts of the world, water scarcity is becoming a major problem. Rapid population growth, climate change, urbanisation, and overuse of groundwater have increased pressure on our water resources. Therefore, we … Read more
Introduction Energy is one of the most important needs of modern society. Electricity powers our homes, industries, hospitals, schools, transportation, communication systems, and everything we depend on in daily life. As the demand for energy increases, countries look for safe, efficient, and reliable sources of power. One such powerful source of energy is nuclear power. … Read more
Introduction Waste is an unavoidable part of human life. Every activity we perform—eating, studying, cleaning, cooking, traveling, and even using electronic devices—produces some kind of waste. With the increase in population, urbanization, and industrialization, the amount of waste generated across the world has increased rapidly. If this waste is not handled properly, it leads to … Read more
Introduction Green energy, also called renewable or sustainable energy, refers to energy obtained from natural sources that are continuously replenished and cause minimal harm to the environment. Examples include solar power, wind energy, hydropower, geothermal energy, tidal energy, and biomass. These sources differ from fossil fuels (coal, petroleum, and natural gas), which take millions of … Read more
Here are 20 questions and answers about hydraulic projects and Pascal’s law, suitable for an science exhibition: Q: What is Pascal’s law? A: Pascal’s law states that any external static pressure applied to a confined, incompressible fluid is transmitted evenly throughout the fluid in all directions without loss. Q: Who formulated Pascal’s law? A: The … Read more
Pascal’s law is applied daily in hydraulic systems, such as in vehicle brakes, where a small force on the brake pedal is transmitted to multiply stopping force at the wheels. Other applications include hydraulic lifts at auto shops, hydraulic jacks for lifting heavy objects, and hydraulic presses used in manufacturing Hydraulic Brakes When you press the … Read more
