Design Lab - Kinetics (DCP, CE sections)
I'm not sure the exact score I received on this, but I scored a 6 overall on HL Chem. My unmoderated IA scores were projected 5-6s from what I remember.This has only the DCP and CE sections, as we submitted the Design part separately and I have no idea where it is.

Dissolved Oxygen in Water when adding Magnesium Chloride
Before I quit chemistry IB SL I had to do quite a few internal assessments. Since i am not in the program any loner, therefore my IA will not be turned it, I decided to put it to good use and upload it here. It was, according to my teacher, worth an IB 6. I received a 95% in the regular grading system. Students can feel free to use this idea, seeing as since it will not be turned into the IB, it will just disappear into my files on my laptop.

Conservation of Mass in Copper Reactions
This lab investigates the strengths and weaknesses of experimental procedure. By holding the law of conservation of mass to be true, the experimental results show exactly how much error the procedure caused. In the IA rubric of analysis and evaluation, the report scored 5 and 6 respectively, for a total of 11/12.
