To investigate the factors which may affect the resistance of resistance putty Planning There are three different factors, which may affect the resistance of resistance putty. These three factors are temperature, length and thickness. To investigate the temperature it is very hard to make the temperature go up/down in certain intervals, it's also hard to connect the connecting wires to the putty itself. If I were investigating the temperature, the putty would have to be placed in a water bath with a Bunsen Burner underneath. If investigating length, it is easier to connect the connecting wires to the putty whilst making sure only one variable is changed i.e. temperature has to stay the same, thickness the same, but only length changes. If investigating the thickness, the shape and length has to stay the same i.e. rounded shape at the end or square, but only the thickness changes. The thickness could either...
