Conductor or Insulator?

Conductor or insulator? In Mr. Matus's science class, we learned about electricity and what it can flow through. We tried many different things, including a paperclip, a pencil, and tape. Out of those, one of them worked, and the light bulb lighted up when we placed it on the battery. The others... not so much. We made predictions on what would light the light bulb up, and we were surprised when some of them were wrong. We learned a lot, and it was one of the best parts of science class in 5th grade.
