Today in class I began my 3rd and final trial. I think there was a possible experiment error with my water heaters, because the temperatures in the three tanks felt very close in temperature when i put my hand in each one. I think it is possible that one or more of the heaters was unplugged then plugged back in by someone. Despite this possible mistake, my results were consistant with my first two trials. Tomorrow is my last day of experimenting and collecting data. I will then start my full analysis and lab report.
