Criteria Feedback
The student's research question is focused, measurable, and clearly connected to a specific physical system.
The student justifies several design choices well, including the use of a motion detector, repeated trials, and a linearized relationship for analysis.
The student's method is detailed enough that another student could follow most of it with only minor clarification needed.
The student should define the independent variable more precisely from the start by distinguishing added mass from total oscillating mass.
Some methodological details still need tightening, especially detector settings and the exact peak-counting convention.
A few design justifications could be more scientifically precise, particularly the role of amplitude in SHM.

B.3Data processing quality
Good
Criteria Feedback
The student's tables and graph communicate the raw and processed data clearly and in an organised way.
The student shows a sensible processing sequence from ten-cycle times to periods, then to T2, a gradient, and finally the spring constant.
The student includes uncertainty handling through repeats, error bars, propagated uncertainty, and max/min trendlines.
The uncertainty method is not always explained clearly enough for the reader to follow without inference.
Some processing and interpretation points need tighter precision, especially the expected reference value and the treatment of systematic effects.
A few presentation choices, such as very small error bars and a rounded R2 value, reduce clarity slightly.
