Criteria Feedback
You frame the investigation in a specific and appropriate real-world context and clearly connect it to the physics being tested.
Your method is detailed enough that another student could largely reproduce the investigation.
You justify several methodological choices well, including the selected pressure values, frame rate, and use of Tracker.
Some procedural details are still not fully operationalized, such as exact camera positioning and how alignment was checked.
The justification for data sufficiency could be stronger, especially around the number of trials and control of conditions.
A few steps rely on human judgement, which leaves small ambiguities in the procedure.

B.3Data processing quality
Excellent
Criteria Feedback
Your tables and calculations are clearly organized and easy to follow.
You communicate the processing steps transparently, including a worked example of the mean and uncertainty calculation.
Your data processing is mathematically appropriate and supports the patterns you identify in the investigation.
You make effective use of graphs, fitted lines, and R² values to show the relationship in the data.
Uncertainty is not carried through consistently for all data points and processed values.
The uncertainty in the starting height is not included, even though it affects the derived outcome.
Your reported precision is sometimes finer than the measurement resolution supports.
The uncertainty treatment would be stronger if it were applied consistently to every pressure condition and shown more fully on the graphs.
