Unit 3- Forms of Energy/Circuits Review

All of the objects below are conductors of electricity EXCEPT...

• an aluminum nail

• a rubber band

• a copper penny

• a steel fork

For the bulb to light, the object students should place in between the wires must be-

• a conductor of electricity

• made of wood

• at room temperature

• an insulator of electricty

Trevor plugs in a lamp. When the lamp is turned on, electrical energy is being converted into-

• chemical energy

• sound energy

• light energy

• mechanical energy

An object produces sound because it-

• reflects heat from the sun

• generates electrical energy

• causes the air to vibrate

• Mechanical energy

• Thermal energy

• Sound energy

• Light energy
