IB Physics HL Internal Assessment Example

The student developed a focused, measurable research question with clear variables and a practical experimental context.

The student included thoughtful control-variable considerations and enough procedural detail to show how the investigation was intended to work.

The scientific framing is not yet specific enough to isolate the main causal mechanism behind the splash effect.

Some steps and solution-preparation details remain ambiguous, which makes full replication difficult.

The student's raw results are organized clearly, making it easy to trace the pattern in the measurements.

The student presented a graph and processed values that make the overall trend in the data visible.

The student showed some awareness of uncertainty through repeats, error bars, and gradient uncertainty.

The uncertainty treatment is not consistent across the dataset and is not handled with enough precision.

Some processed values and table labels are unclear or repetitive, which weakens the traceability of the analysis.

A few numerical choices reduce accuracy, such as rounding away information and applying one spread to all concentrations.
