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
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
This project demonstrates the human digestive system by using simple materials to mimic each stage of the process. It highlights how food is broken down mechanically and chemically, how nutrients are absorbed, and how waste is formed and expelled. By understanding each component’s function and the overall system’s operation, students can gain a clearer understanding … Read more
