Syllabus objectives

Status is based on evidence, never on a single answer.

  • Describe evidence of a chemical reaction

    S1.1 · Knowledge · Described three reaction indicators unprompted

    Secure
  • Balance symbol equations

    S1.2 · Knowledge · Changed subscripts instead of coefficients — misconception identified

    Ready to revisit
  • Identify variables in an investigation

    S2.1 · Experimental design · Named control variables with prompting

    Practising
  • Draw conclusions from results tables

    S3.1 · Data interpretation · Read the trend, conclusion needed more detail
