Amazing liquid conductor
Students will mix a variety of liquid solutions together to see if they will light a light bulb in a electrical circuit. They will be able to identify liquid electrical conductors and nonconductors. Also they will be able to identify that liquid solutions that contain a noticeable amount of acid or salt are good conductors of electricity. Each group of students will make a closed circuit to test their solutions.
