A string of lights with small bulbs is shown below. The bulbs are connected by wire that is covered in an insulator. When the lights are on, electricity travels in....

• a complete circuit

• a sound wave

• a light ray

• an incomplete path

A fifth grade class constructed this circuit.  Which of these objects most likely made the light glow when connected to points X and Y?

• plastic straw

• cotton string

• aluminum foil

• rubber eraser
