“Each metal has a certain power… of setting the electric fluid in motion”
Electrical conductivity is a measure of a material’s ability to conduct an electric current. Students in the CIE 5 class constructed a circuit using various electrical components such as a battery, wires, a switch, and a light bulb.
They then integrated different materials—including an iron nail, pencil lead, aluminum foil, an eraser, and paper—into the circuit to test their electrical conductivity. Additionally, they endeavored to classify these materials as insulators or conductors and successfully identified their practical applications in everyday life.
