Electrical Conductivity Tester PDF

Conductors allow the free flow of electrons, while insulators do not. This lab will give the kids an opportunity to build a circuit that allows them to sort materials as conductors or insulators. To do this, the kids will use a D cell battery in a clip, 3 test leads and a 1.5 volt light in a socket to assemble a simple circuit used to test different kinds of materials. They will begin to formulate a “law” of conductivity which they will support using their data. Graces 4-8
