IB Physics HL Internal Assessment Example

The student placed the investigation in a clear and scientifically appropriate astronomical context.

The student explained why the semi-major axis and the eight-planet dataset are relevant to their aim.

The student's methodology is mostly reproducible because they identify the source, show the processing steps, and include code.

The comparative wording of the research question is not fully operationalized.

Some data-selection and retrieval details are still too vague for complete replication.

The student's justification for uncertainty choices needs to be more carefully supported.

The student's raw-to-processed data trail is clear and easy to follow.

The student includes a worked example that shows how the processing and uncertainty propagation are done.

The student's calculations and regression-based processing are mostly appropriate and communicated well.

The uncertainty treatment is not fully consistent across the written explanation, tables, and code.

Some uncertainty values are based on display precision rather than clearly validated source uncertainty.

The processing would be stronger if the planet-by-planet uncertainties were used consistently in the regression and graph.
