The hypothesis is that when the temperature of a wire increases, the resistance value of the wire will also increase and therefore the conductivity of the wire will reduce.

You will wind a wire around a PVC pipe, measure the resistance of the wire, connect the wire to a battery, measure the current, and measure the temperature of the wire as it increases.

You will need a varnish insulated copper wire, a PVC pipe, three 1.5V batteries, jumper wires, an ohm meter, an ammeter, a paper knife, an infrared thermometer, and insulation tape.

The experiment showed that as the temperature of the wire increases, the resistance of the wire also increases but the current flowing in the wire reduces. This confirms the hypothesis that when the temperature of a wire increases, the resistance value of the wire will also increase and the conductivity of the wire will reduce.

This science project is interesting because it shows how temperature affects the resistance of a wire and how it affects the flow of electricity.

Variations of this experiment could include repeating the experiment using different wire sizes or using aluminum wires.
