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
Aim / Objective: To demonstrate how hydraulic pressure can be used to lift and move heavy objects by transmitting force through a liquid using syringes and pipes. Materials Required: Working Principle: This model works on Pascal’s Law, which states that pressure applied to a confined fluid is transmitted equally in all directions.When the piston of … Read more
Aim / Objective: To demonstrate how a capacitor stores electrical energy during charging and releases it during discharging, showing its use in controlling and stabilizing electric current. Materials Required: Working Principle: A capacitor is an electrical component that stores energy in the form of an electric field between two plates separated by an insulator (dielectric). … Read more
Here’s a comprehensive list of Zoology Working Model Ideas suitable for school or college exhibitions — covering topics like human anatomy, animal physiology, ecology, evolution, genetics, and more.I’ve grouped them into categories to make it easy to choose from. Human Anatomy & Physiology Models 1)Human Heart Working Model (with blood circulation) The human heart is … 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
1. Introduction to Motion Motion is one of the most fundamental concepts in physics. It describes the change in position of an object with respect to time. From the planets revolving around the sun, the movement of vehicles on the road, the swing of a pendulum, to the microscopic motion of particles inside matter – … 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
