Light a Bulb Inquiry

This simple inquiry lab challenges students to light a mini bulb using only a battery and one short wire. Even students who have seen circuit diagrams may be stumped when they have only one wire. Students will also discover how light bulbs are constructed, with a partial circuit that leads from the outer base, through the filament, to the bottom of the base. Their circuit must touch each of the two parts of the base to work.
