IB Biology HL Internal Assessment Example

The student framed a focused and investigable question and linked it to a relevant biological context.

The student identified several methodological variables that matter for collecting meaningful data.

The student's procedure is organized enough that another reader can follow the main sequence of the investigation.

The scientific context is still broader than it should be for the exact endpoint the student measured.

The endpoint needs a sharper, more precise definition so the investigation tests one clear change rather than several possible effects.

Some choices in the method are not explained well enough to show why they are the best way to answer the question.

The student recorded raw and processed data in a way that lets the reader follow the investigation.

The student included means, standard deviations, and a statistical comparison, which shows real processing rather than just description.

The student made an effort to include uncertainty and units in their tables.

Some of the recorded values do not distinguish between groups well enough to be analytically useful.

The way uncertainty is presented is inconsistent and not always matched to the quantity being measured.

The graph and some of the processing are not communicated with enough clarity and precision to make the trends easy to verify.
