Practice Chemistry IA (analysis and eval only) - Order Determination
"What is the order of reaction of hydrochloric acid (HCl) in the reaction between marble chips and HCl?" was my research question. this was a really straightforward practical because it was just for practice, and our teacher only got us to do the analysis and evaluation section, marking the whole thing out of 12 (this scored a 10/12)

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.

22/24 Marks Practice Chemistry IA on Ethanoic acid in vinegar
This is an IA I did for HL Chem in DP1, we were pretty much given the topic and I don't think it would be enough for a final IA, but my teacher said it was probably the best she read. I can't remember where I lost the two marks but the main issue with the assignment was that I didn't really have a literature value to compare to, or a scatter graph (which my school requires).

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.

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.
