physics working models for science exhibitions
This is a 3-pulley simple machine working model. It shows how pulleys reduce the amount of effort needed to lift a heavy object. The movable pulley provides a mechanical advantage, and the fixed pulleys change the direction of force. Such systems are used in cranes, wells, and elevators.” Materials Needed How to Make Simple pulley … Read more

An electric current circuit working model demonstrates how electricity flows through a closed loop, powering devices like lights or buzzers. It also shows the difference between an open circuit (no flow of electricity) and a closed circuit (electricity flows). Key Components: Open Circuit: Closed Circuit: How the Model Works: Demonstration: Open Circuit: https://www.youtube.com/@howtofunda
A household circuit is designed to supply electricity to various appliances in a home, such as lights, fans, and other devices, while ensuring the safe flow of electricity. This working model demonstrates the basic principles of a household circuit, showing how power flows from the power source (battery) to the connected appliances through switches. Components … Read more
