IV and ?T vary (Investigate power with ?T) 3- IV and m fixed. t and ?T vary (Investigate ?T with time) Where- t=time IV=power M=mass of water S=specific heat capacity ?T=change in temperature Planning- Planning a suitable method- We are only changing 2 variables in our experiment, the controlled variable and the measured variable. Other than that, all the other factors are constant and need to be maintained that way. For our prelim and actual experiment we did this by testing the equipment before the actual experiment.
