The purpose of this experiment is to investigate how resistance varies with temperature for a metallic conductor, insulators, and semiconductor diodes. What exactly are these things? A semiconductor is a material having resistivity between that of a conductor and an insulator. It usually has a negative temperature coefficient of resistance. The diode is any electronic device with only two electrodes. They are now semiconductor devices. A conductor is a substance, or a body, that offers …

…the experimenter used, though, did not effect the insulators. The experimenter tried to eliminate any errors by using about the same range of temperature for each object. The experiment could have been improved by having a better heating device, maybe one that you could change the range of temperature by switching a dial instead of having different temperatures in different spots. The experimenter learned that it isn't that easy to experiment with such little things.
