electromagnetic crane working model for school science fair project howtofunda

Making water level indicator working model, in this course teaches students how to design and build a functional model that detects and indicates the level of water in a tank or container. Through hands-on experiments, learners explore the concepts of electricity, conductivity, and automation. The course explains how sensors or simple probes can detect different water levels and trigger LEDs or buzzers accordingly. Using materials such as wires, LEDs, resistors, transistors, and a power source, students create a working circuit that lights up or sounds an alarm when the water reaches specific points. This course helps students understand real-life applications of electronics in water management and conservation. Ideal for school science projects and exhibitions, it promotes practical learning, innovation, and awareness about efficient resource use by combining basic engineering and environmental science concepts. howtofunda
