simple circuit working model school project for science exhibition DIY howtofunda

open circuit and closed circuit working model, in this course introduces students to one of the most fundamental concepts in electricity. In this course, learners will explore the difference between open and closed circuits and understand how electric current flows. Through step-by-step guidance, students will design and build simple working models using batteries, wires, switches, and bulbs. The course demonstrates how a closed circuit allows electricity to flow, lighting the bulb, while an open circuit breaks the flow, causing the bulb to turn off. Learners will also study the role of key components such as conductors, insulators, and switches in controlling the current. Practical experiments are included to strengthen understanding and show how these principles apply to real-life electrical systems at home, school, and industry. By combining theory with hands-on practice, the course makes learning electricity engaging and interactive. By the end, students will have both a clear grasp of electrical circuits and a functional model ideal for science fairs, classroom demonstrations, or home projects. howtofunda
