Aim:
The aim of this investigation is to investigate and discover if the length of a piece of metal wire effects its resistance when electricity is passed through it.
Prediction
Before I make a prediction I shall explain about atoms, free electrons, electricity and resistance.
Electricity travels through a conductor, in this case a length of wire, by means of free electrons. Electrons are the smallest parts of an atom that is situated in shells (…

…would have made it any more accurate. I feel that the only way to make it more accurate would be to use a different method - perhaps were we had a thin metal bar that was strong and did not bend like the piece of wire. We could have used a different instrument like an ohmmeter to measure the resistance instead of measuring the voltage and current and then dividing the voltage by the current.
