In this lab, students create an open circuit to test if different materials conduct or insulate electricity. The students place the object in the open circuit and observe if the item is a conductor or insulator. Then, students will describe the physical property that makes an item a good conductor or insulator.
I have included a copy with the materials I have my students test. I have also included a blank copy, so you can select your own items to test. I have my students complete this lab in partners (using Christmas lights).
