Methodology description
Criteria Feedback
- Research question situated in a highly specific chemical context linking Arrhenius behaviour, photon energy and glow-stick mechanism
- Methodological considerations are systematically explained, with independent/dependent variables justified, six controlled variables tabulated and rationales given
- Procedure is detailed with clear volumes, times, temperatures, photographs and diagrams supporting reproducibility
- Minor ambiguities remain (exact size of aluminium enclosure and construction of the ‘steepest line of worst fit’ could be more precise)
- Dependent variable description could more explicitly link lux measurements to reaction rate for clarity

Consideration of uncertainties
Good
Data processing quality
Criteria Feedback
- Data tables and graphs are clearly labelled with units and uncertainties, and error bars are included to illustrate uncertainty impact
- Uncertainty propagation formulas are applied correctly in principle, demonstrating strong conceptual understanding
- Overall communication of data recording and processing is clear and precise
- Propagation mixes relative and absolute uncertainties in places, and some error bars are invisible due to scaling
- Headings misalign in uncertainty tables and a misprint (Δ(1/π) instead of Δ(1/T)) reduces precision
- Numerical inconsistencies (mismatched Ea table entries) and absent worst-fit line sketch introduce significant but non-critical inaccuracies
