Grade V - Water level indicator activity
Students of grade V made a Water level indicator during their Young Scientist Club .A water level indicator is a device that provides information about the water level in a tank or reservoir. It can help you monitor the water level and prevent overflow or dry running of the pump. The water level indicator works by using the principle of electrical conductivity. When the water level in the tank or reservoir rises, it comes into contact with the other one of the wire making the circuit close and thus current starts flowing which leads to buzzer sounds, an alarm or the Led to glow or both.
