A student used a battery, light bulb, and wires to create the diagram shown. For the light bulb to turn on, the object that a student must place at the gap between the two wires must be --

• a conductor of electricity.

• made of plastic.

• made of wood

• an electrical insulator

Elijah places four different materials at the same temperature onto a hot plate to find out which material is the best insulator. The information presented in the table shows the temperature of each material after 15 minutes.

Elijah can conclude that which of the following materials is the best insulator?

• Material #1

• Material #2

• Material #3

• Material #4
