Methodological considerations
Criteria Feedback
- Research question is described within a specific and appropriate context (champagne bottle as a Helmholtz resonator).
- Clear measurement description of neck length and background details (volume, neck dimensions, water displacement).
- Numbered procedure with materials list and photographs supports reproducibility for most steps.
- Identification and statement of controlled variables (bottle cleanliness, table surface, quiet room) shows careful planning.
- Key procedural details remain ambiguous (precise microphone distance, blowing angle/technique, environmental temperature).
- Controlled variables are stated but not quantitatively justified or linked to their impact on data precision.
- Some theoretical definitions (eg. v, L in formula) are referenced elsewhere rather than included at point of use.

Consideration of uncertainties
Excellent
Data processing quality
Criteria Feedback
- Data recording and processing are communicated clearly and precisely—with raw and processed tables, units, uncertainties, labels, and error bars.
- Data processing steps (averages, inverse volumes, linear regression) are carried out appropriately and accurately, yielding a strong correlation (r = 0.9998).
- Sample calculations and consistent use of uncertainty estimates aid transparency and support conclusions.
- Propagation of uncertainty through transforms (eg. ΔV → Δ(1/√V)) is omitted, understating random errors.
- Systematic uncertainties (ambient temperature, app calibration) are ignored despite being conceptually significant.
- Graph axes occasionally omit units or labels, and some redundant calculations clutter the presentation.
