Lesson-specific diagram for Integrated Chemistry 11 modelling capstone. It visualizes the reasoning sequence tied to $\text{represent}\to\text{calculate}\to\text{test}\to\text{evaluate}\to\text{communicate}$. Text alternative: Construct and defend a chemistry model of a local or supplied system using at least three course strands, quantitative evidence, uncertainty, and appropriate source/place protocols.
