Answer:
1. The materials that are good conductors of heat and electricity are the coin, copper wire, metal spoon, and paper clip. This proves that metals or objects made of iron are good conductors.
2. The insulators among the materials are the comb, paper, pencil, eraser and toothpick. This proves that materials/objects not made of iron are not good conductors of heat and electricity.
