Concept / Principle: This project demonstrates how solar energy can be converted into electrical energy using solar panels to power small household components like LED lights, fans, or a motor — showing the concept of renewable energy and sustainable living. Scientific Principle:Solar panels contain photovoltaic (PV) cells that convert sunlight (solar radiation) into electricity (DC … Read more
Concept / Principle: The hydraulic crane works on Pascal’s Law, which states: “Pressure applied to a confined fluid is transmitted equally in all directions.” When you push fluid (water) from one syringe, it transfers pressure through a tube to another syringe, causing movement — just like in real cranes that use hydraulic systems to lift … Read more
Concept / Principle: A geostationary satellite is a satellite that orbits the Earth once every 24 hours — the same time the Earth takes to rotate once on its axis.Because both rotate at the same rate in the same direction, the satellite appears stationary above one fixed point on Earth (like over India or the … Read more
This model demonstrates the laws (rules) of exponents in an interactive and visual way.Using a rotating wheel or disc system, each rotation reveals a different law of indices with an example — helping students easily understand how powers behave in multiplication, division, and powers of powers. Laws of Indices / Exponents: 1️⃣ Product Law:am×an=am+na^m \times … Read more
Concept: This interactive maths model helps students understand the surface area and volume of 3D geometric shapes like cube, cuboid, cylinder, cone, sphere, and pyramid.The LED light glows when you press the correct formula button for a given shape, and the buzzer alerts when it’s incorrect — turning a simple model into a fun learning … Read more
