Answer:
Twist two or three strands of the iron wire together, then twist the ends around the hooks in the copper wire. The iron wire will act as your filament. Place the lid (with the filament and wires attached) in the jar and carefully connect the free ends of the copper wire to the terminals on the 6-volt battery.
