IB Geography SL Internal Assessment Example

The student identifies a clearly geographical, location-specific investigation in Mambrui that is easy to place spatially.

The student's maps provide useful context and include key conventions such as titles, north arrows, keys and scale bars.

The question is linked to coastal geomorphology and supports testable hypotheses using measurable variables.

The research question would be stronger if the dependent variable were defined more precisely.

The hypothesis about soil pH would be clearer if the student stated the expected measurable direction or range more explicitly.

Some map labelling and hand-drawn presentation elements are a little imprecise.

The student chooses methods that fit the investigation well, including quadrats, pH readings, anemometer use and dune-height measurement.

The student explains some reliability steps, such as calibration and rinsing the pH probe.

The student's methods show that the fieldwork was actually carried out over a planned time frame.

The sampling strategy is not fully consistent because random sampling is described alongside choosing the best areas.

Key procedural details are missing, including probe depth, number of repeats at each site, anemometer height and recording duration.

The method for measuring dune height needs clearer standardization to make it fully replicable.
