To explain the working principle of a smoke absorber built using cardboard, a DC motor, and a filter. This smoke absorber demonstrates basic principles of air filtration, showing how fans and filters can work together to improve air quality. By understanding these principles, we see how simple devices can address environmental issues. Working Principle: Summary: … Read more
This model demonstrates the concept of gravity, which is the force of attraction between two masses. While the gravitational force between the small thermocol balls is very weak and may not be easily observable, this model helps visualize the concept that all objects with mass attract each other. In the context of Earth, gravity is … Read more
A simple water dispenser using a plastic bottle works by utilizing gravity to dispense water through a tap. By filling the bottle and positioning it on a stand, users can easily control the flow of water using the attached tap, making it a practical and efficient model for demonstrating basic principles of fluid dynamics and … Read more
A simple mobile projector using a cardboard box, convex lens, and mobile phone works by utilizing the lens to focus light from the phone’s screen, projecting an enlarged image onto a surface. By adjusting the distance between the phone and the lens and ensuring a dark environment, this model effectively demonstrates basic principles of optics … Read more
This experiment demonstrates the principle of refraction using a convex lens. A convex lens converges light rays passing through it, forming a real, inverted image on the opposite side. By adjusting the distances between the candle, lens, and screen, you can observe changes in the image, illustrating how lenses are used in various optical devices … Read more
