Frequently Asked Questions

How do I choose a feasible Chemistry IA topic within the time and resource constraints?

Feasibility is crucial when selecting your Chemistry IA topic. Consider the equipment and materials available at your school, the time required to collect sufficient data, and your own expertise in laboratory techniques. A feasible topic should allow you to complete data collection within 10-12 hours of practical work, which typically spans 2-4 weeks depending on your school's timetable. Avoid topics requiring specialised equipment or hazardous procedures that your school cannot safely accommodate, as this will compromise both your safety and the assessment criteria for practical skills.

What are the key differences between HL and SL Chemistry IA topics?

Whilst the internal assessment structure is identical for both HL and SL students, Higher Level candidates are expected to demonstrate greater depth and sophistication in their investigations. HL topics often involve more complex variables, quantitative analysis, or theoretical frameworks, whereas SL topics typically focus on more straightforward relationships and data collection methods. Both levels must achieve the same assessment criteria, but HL students should consider topics that allow for more advanced exploration of chemical principles, such as investigating factors affecting equilibrium constant values or analysing buffer capacity across a wider concentration range. Explore our detailed guide on Le Chatelier's principle for more tips.

What data collection methods work best for Chemistry IA investigations?

The most reliable data collection methods depend on your chosen topic, but generally involve quantitative measurements using appropriate laboratory equipment. Titration, temperature monitoring with data-logging equipment, spectrophotometry, and mass measurement are all common approaches that yield precise, repeatable results. Your method must be systematic and allow for multiple trials—at least three replicates per data point—to ensure valid conclusions about uncertainty and errors. Qualitative observations should support your quantitative data but should never form the primary evidence base, as the IB emphasises measurable, analysable results.

What common topic mistakes should I avoid in my Chemistry IA?

Many students choose overly ambitious topics that require excessive time or resources, such as synthesising complex organic compounds or investigating reaction kinetics across extreme temperature ranges. Others select topics that are too vague, making it difficult to collect meaningful data or draw conclusions, or they choose investigations where the outcome is already well-established in literature, leaving little room for genuine personal engagement. Avoid topics that depend entirely on qualitative observations, those requiring hazardous chemicals or procedures your school cannot support, and investigations where you cannot collect at least 15 meaningful data points for analysis.

Should I choose an original topic or something based on existing research?

The IB encourages personal engagement and originality, but your topic should be grounded in established chemistry concepts and, ideally, related to published research or recognised experimental procedures. Completely novel topics often lack proper scientific foundation and may be difficult to analyse meaningfully. Instead, aim for a topic that applies familiar chemistry principles in a slightly novel context—for example, adapting a standard titration method to analyse a real-world sample or investigating how a parameter that textbooks typically hold constant actually affects your chosen reaction. This balance demonstrates both scientific integrity and genuine intellectual curiosity.

How should I evaluate whether my topic meets IB assessment criteria before I start?

Before commencing your investigation, carefully review the assessment criteria for personal engagement, exploration, analysis, and evaluation. Your topic should allow you to justify your research question, explain the underlying chemistry authentically, demonstrate practical competence through controlled data collection, analyse your results using appropriate mathematical and statistical methods, and reflect critically on limitations and sources of error. Consider consulting with your chemistry teacher or an IB tutor to ensure your topic offers sufficient scope across all criteria.
