MATERIALS REQUIRED Item Quantity Description Cardboard As needed Thick (for arms and base) Syringes 4 … Read more
Welcome to this DIY Science Project on how to make a Biogas Plant Working Model that shows how organic waste can be converted into renewable energy and electricity! In this video, we demonstrate a miniature biogas plant setup that produces biogas from kitchen waste and cow dung, and shows how that gas can be used … Read more
In this physics project, we demonstrate the charging and discharging process of a capacitor using simple components like a capacitor, resistor, LED lights, and two switches. This model helps students visualize how energy is stored and released in electronic circuits — one of the most important concepts in physics and electronics. What You’ll Learn: Materials … 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
1. Introduction The human heart is a muscular organ responsible for pumping blood throughout the body. It supplies oxygen and nutrients to tissues and removes carbon dioxide and waste products. The heart works as a pump in the circulatory system, functioning non-stop from birth to death. On average, the heart beats 72 times per minute … Read more
1. Introduction The human eye is one of the most complex and important sense organs. It allows us to perceive the world through the sense of vision. Almost 80% of all information we receive comes through our eyes. The eye works like a natural camera, capturing light and converting it into signals that the brain … Read more
1. Introduction Agriculture is the backbone of human civilization and the primary source of food. Crop production and management involve the scientific methods used to grow crops efficiently to meet the growing demand for food, fiber, and raw materials. With the world’s population increasing, efficient crop management is vital for food security. Modern farming involves … Read more
1. Introduction Health is wealth, and one of the most important factors that determine good health is nutrition. Food provides energy and nutrients required for growth, repair, and maintenance of the human body. However, merely eating food is not enough — the food must be nutritious and balanced. A balanced diet is essential for proper … Read more
1. Introduction Agriculture is the practice of cultivating plants, rearing animals, and producing food, fiber, and other essential products for human life. It is the backbone of human civilization and plays a vital role in the economic and social development of a country. About 70% of India’s rural population depends directly or indirectly on agriculture … Read more
Introduction Water is the most vital resource on Earth, essential for all forms of life. Approximately 71% of the Earth’s surface is covered with water, but only 3% is freshwater, and a significant portion of it is inaccessible as it is locked in glaciers, ice caps, or underground. Rapid population growth, industrialization, urbanization, and climate … Read more
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 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
