In Class 11, we’re becoming experts in making circuits, so we decided to challenge ourselves even more by adding different materials to our circuits. This included rubbers, rulers, paper clips and scissors. We predicted that, if the material is made out of metal, it will conduct the electricity and complete a circuit to make the bulb light up. If it was made of plastic or other non-metallic materials, it was an insulator, because the electrical flow would be prevented. We were correct! See Class 11 below in full science mode:
