IB DP Physics HL Internal Assessment

Personal Engagement
My research question for the internal assessment on physics DP course is “What is the relationship between the length of the pencil and resistance of graphite?” I had come out with this research question while I was learning about the electric current through different objects, I was curious about the graphite inside the pencil would be suitable for conducting electricity. I knew that graphite is nonmetallic substance, but I wasn’t familiar that it does conduct electricity, so I was interested on that characteristic of graphite and encouraged me to investigate on this topic.

Introduction and Background
The aim of this investigation is to find out the relationship between the length of the graphite and resistance of graphite. I will collect the raw data with measuring the current of the graphite depending on its length. Then I am going calculate the resistance of it and find out what are the patterns to determine the relationship between length and resistance…
