This is a detailed Nuclear Power Plant Working Model. The process starts in the fusion building (reactor), where nuclear fission generates heat. This heat is transferred via hot water pipes to the turbine building, where steam spins a turbine connected to a generator.Electricity is produced and sent through transmission lines to homes.The excess heat is … Read more
This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more
A hydraulic brake uses liquid pressure to transfer force from the brake pedal to the brake drum to stop a vehicle. In this working model, you will show how pressing a “brake pedal” moves hydraulic fluid (water or oil) through a tube to push a “brake shoe” against a “drum” (wheel). Working Principle Demonstrated: Pascal’s … Read more
This is a working model of an electric bell. When the switch is turned ON, electric current flows through the circuit, powering the DC motor. The motor rotates the nut attached to its shaft, which hits the steel glass to produce a sound. This demonstrates the basic idea of how electric bells use mechanical action … Read more
