One of the biggest challenges facing students taking IB chemistry is coming up with a good Internal Assessment (IA) idea.
It’s got to be something suitably demanding for diploma-level study, it’s got to be something relevant to the chemistry syllabus, it’s got to be something you can’t just look up the answer to in a textbook, and crucially, it’s got to be a topic the student is personally engaged with.
Many students are unsure how to relate the IB chemistry topics to a real-world situation or problem that they can investigate. To help with this, I’ve produced a list of chemistry IA ideas, together with some example Research Questions (RQ).
I’ve grouped them together according to the main experimental technique or measurement method.
A big fat disclaimer
This is a list of ideas only, intended as a source of inspiration for students who are stuck for an idea.
It is a starting point for further research, not a list of off-the-shelf projects you can select from and take to your teacher.
Please do not just copy directly from this list!
There are several reasons why you shouldn’t do this:
Firstly, one of the internal assessment criteria is Personal Engagement. This is about how well you engage with the project and make it your own.
To achieve the maximum score “The evidence of personal engagement with the exploration is clear with significant independent thinking, initiative or creativity. The justification given for choosing the research question and/or the topic under investigation demonstrates personal significance, interest or curiosity. There is evidence of personal input and initiative in the designing, implementation or presentation of the investigation.”
It should be clear from these guidelines that you need to choose your own project and completely own it.
Secondly, some of the projects below are just plain bad for reasons I’ve outlined in my post about research questions.
These reasons include:
- The RQ is just a title
- The RQ is unfocused and unclear – impossible to understand what the aims are
- The RQ doesn’t include any variables
- Project is unimaginative
- Project has obvious outcomes
- Project is just a series of measurements or a synthesis, rather than an investigation
I’ve given a weaker and a stronger example research question for each category, but be aware that the stronger research question is not necessarily a good research question!
With that out of the way, here’s the list:

Hello, I’ve been struggling for a while to come up with a type of question to be able to do an IA with. I’m interested in a topic having to do with pesticides but the thing is that I am not really sure how to convert it into an actual strong question. Can you please help? help/tips would be greatly helpful! Please and Thank you!

Hi, I wanted to determine protein content of something over different cooking time but I did some research on the google and I found that proteins are not affected by heating. So if I do this experiment, I will not see any difference in the protein content. Shoul I do this experiment? If I do this experiment and I write it as a IA, Will I get higher points? Will conclusion affect my point. Thank you

Hi, thanks for this nice article! I was thinking of investigating fragrance esters,specifically whether amount of unsaturation affects smell characteristics and volatility of the molecule? I am not sure how I can develop this up into an RQ. Any help you can give is appreciated. TIA
DrCarlThirskNovember 12, 2018 at 1:17 pm - Reply
Hello Astridde, glad you find the article useful. The issue I can see to begin with is you have two dependent variables, volatility and smell characteristics. Volatility can be quantified and measured (e.g. vapour pressure) but ‘smell characteristics’ you would have to think how you can quantify and measure. Linking volatility and your independent variable (number of double bonds?) also sounds too simplistic to me as you can quite easily predict that relationship.
The earlier post I wrote on research questions will hopefully help.

FAQs
What is a good chemistry IA topic? ›
IB Chemistry IA Ideas - Stoichiometry
Explore the drug content in tablets. How does the concentration of ethanoic acid-present in vinegar as determined by acid-base titration - get affected by a change in temperature while cooking? Investigate Vitamin C content of different food products.
Data you always have to mention your entire range so this would include things such as concentration
What is a research question in chemistry? ›A research question is an actual question you want to answer about a particular topic. Developing a question helps you focus on an aspect of your topic, which will streamline your research and writing.
What makes a good IA research question? ›A good IA relies more than anything else on a good starting point: a well-defined, narrow question with some element of a debate. Should allow for a point to be made, or a debate to be settled. It should not lead to a simple narrative. Must be specific – narrow it down as much as you can.
