Scientific Inquiry: notes and practice questions

This topic covers the initial stages of scientific inquiry, focusing on developing a research question, designing an investigation, and controlling variables. Formulate clear research questions and testable hypotheses.

This topic extends the application of inquiry skills to exploring and designing investigations for the more complex chemical systems and phenomena covered at Higher Level. Formulate research questions and hypotheses that integrate advanced theoretical concepts from the HL syllabus.

This topic covers the essential skills for gathering, organizing, and making sense of experimental observations and measurements in chemistry. Identify and record relevant qualitative observations and sufficient quantitative data.

This topic covers the skills required to draw and justify conclusions from experimental data and to critically evaluate an investigation's methodology. Interpret processed data and analysis to draw and justify conclusions.

This topic extends uncertainty propagation to calculations involving exponents. For a quantity $y = x^n$, the fractional uncertainty is $\frac{\Delta y}{y} = \left| n \frac{\Delta x}{x} \right|$.

This topic covers the application of concluding and evaluating skills to the broader and deeper content of the HL chemistry syllabus. Students are expected to demonstrate a more sophisticated understanding of the impact of uncertainties on conclusions.
