Does the length of wire affect the brightness of a bulb?

This is the question Year 6 has been investigating this week. Armed with batteries, bulbs and tissue paper, the children planned and conducted a fair test to reach a conclusion: the longer the wire, the brighter the bulb. Next week, we hope to make either a burglar alarm or a set of traffic lights so if you have an empty shoe box or tissue box, please bring it in.
