Method

Experiment to Test Conductivity

You have a battery, a light bulb, and several materials to test. Connect the battery to the light bulb and introduce each material into the circuit one at a time.

  1. a

    Describe the method you would use to test whether a material is a conductor or an insulator. Include details about the variables you would control and how you would ensure the reliability of your results.

    Aim for approximately 4 distinct marking points.
