IB Geography SL Internal Assessment Example

The student formulates a clear, geographical research question with a strong theoretical link to the Bradshaw Model.

The student's location maps make the study area, site sequence, and downstream focus easy to understand.

The student identifies a precise and feasible fieldwork context for primary data collection.

The written location detail could be even sharper with grid references, coordinates, or named start and end points for the sampled reach.

Some map labels are crowded, which makes a few features harder to read at a glance.

The student chooses methods that are relevant to the hypotheses and clearly connected to discharge, sediment size, and river shape.

The student collects data across multiple sites and includes repeats for some measurements, which shows an effort to improve reliability.

The student explains the purpose of the methods with enough clarity that the reader can follow the general investigation design.

Some procedures need more detail, especially how sampling points were selected and how sediment measurements were standardised.

The velocity method has limitations because a surface float in the channel centre may not represent mean velocity well.

The method write-up would be stronger with fuller justification of how each technique improves validity or reliability.
