PHYSICS PRACTICAL ASSESSMENT PLAN A variable is something that can be changed or measured. The following is a list of variables that can be changed in the experiment that I will be doing: ·Changing the length of the wire ·Increasing the cross-section of the wire ·Changing the material used ·Changing the temperature ·Changing the resistance of the wire ·Changing the voltage going across the wire ·Changing the current going across the wire For my experiment …showed first 75 words of 864 total…

…showed last 75 words of 864 total…straight as possible because last time it may have had kinks in the wire making it longer therefore less accurate. I would probably also repeat the experiment for a third time to get a more precise average of all the results just incase one of the readings went a bit wrong. My results allowed me to make a confident conclusion because the results were so accurate and they show that my prediction was indeed correct.
