Nam Part II: Conductivity of objects Question: What materials will close a circuit? Conductors are materials with easily movable charges, allowing current to occur, Insulators do not have easily movable charges, so current is not produced. Look at the nine Materials at lower left. 1. Which do you think are conductors? Which are insulators? A. Predicted conductor- B. Predicted insulators- C. How could you use your open circuit to test if a material is a conductor or insulator? 2. Experiment: Set-up a "test circuit" using the battery, 2 wires, and a light bulb. Test the conductivity of different objects shown in the left-hand box, such as paper clips, pencils, etc. by inserting these materials into the circuit. You will need to scroll down to see these objects. Drag each material into the gap of the open circuit. If the light bulb lights, the material is a conductor. If not, the material is an insulator. Keep track of your findings below. Conductors Insulators 3. Analyze: Look at your list of conductors. A. What kind of material are most conductors? B. Did any conductor have a different effect on the light bulb than the others? Explain
