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
The purpose of creating a merry-go-round working model is to demonstrate principles of rotational motion, mechanical engineering, and simple electrical circuits. This project helps students understand how a basic motor can convert electrical energy into mechanical energy to produce rotational movement. Creating a working model of a merry-go-round using cardboard, a DC motor, a switch, … Read more
