Criteria Feedback
- You communicate an interdisciplinary topic clearly and show from the start that you are connecting geography and biology.
- Your research question is evaluative and gives the essay a clear argumentative purpose.
- You use a range of source types and make some sensible choices about evidence from both environmental and political contexts.
- The topic is too broad in places, which makes the line of inquiry less controlled than it should be.
- Key wording in the research question is imprecise and would benefit from a clearer time frame, mechanism, and measurable focus.
- You do not explain a clear method for selecting or comparing sources to test the relationship you are investigating.
1.1·Weakness
Page 1
The topic is recognisable, but the phrasing is very broad and awkwardly compressed. The student should narrow the scope by specifying which geopolitical mechanisms matter most and how they affect sea turtles, so the investigation can stay focused on a testable relationship rather than a wide background survey.
1.2·Weakness
Page 1
The key phrase “enabling a growth in the effects” is difficult to operationalise. The student should define what counts as “growth,” which effects on turtles are being measured, and the time frame or policy channels being studied, otherwise the question remains clear in intent but too loose in method.
1.3·Strength
Page 1
The student clearly signals an interdisciplinary lens from the outset. Naming both Geography and Biology helps the examiner see how the investigation will connect environmental patterns with living-system impacts, which is exactly what a World Studies essay should do.
1.4·Strength
Page 1
The research question is framed in an evaluative way with “to what extent,” which is a strong choice because it invites judgment and comparison rather than simple description. That gives the essay a clear argumentative purpose.
1.5·Suggestion
Page 4
The student could strengthen the method by explicitly explaining how the biological and geographical lenses will be combined. A brief method statement naming the source types, comparison strategy, and causal link being tested would make the investigation much more controlled.
1.6·Weakness
Page 4
This explanation overgeneralises the historical relationship and does not yet show how it directly affects the GPGP. The student should avoid broad geopolitical background unless it is tied to a specific mechanism, such as funding, regulation, cooperation, or enforcement that could plausibly change plastic leakage.

Criteria Feedback
- You show solid knowledge of the Great Pacific Garbage Patch and of the biological vulnerability of sea turtles.
- You use source material effectively in places, especially when linking debris composition and turtle migration to exposure risk.
- Your terminology is generally accurate and you demonstrate familiarity with the key environmental and geopolitical concepts involved.
- Some of your source choices are less directly relevant or uneven in quality, so the strongest evidence is not always prioritized.
- Your knowledge is often presented in separate blocks rather than being fully integrated into the central argument.
- A few concepts are handled too generally, which weakens the precision of the biological and political explanation.
2.1·Strength
Page 5
The student gives a clear, accurate explanation of the GPGP’s physical formation. This kind of core contextual knowledge is useful because it grounds later claims about debris accumulation in ocean circulation rather than treating the patch as a vague mass of trash.
2.2·Strength
Page 7
This is a strong use of data because the student does not just list percentages; they interpret what the composition suggests about sources of pollution. That move from evidence to implication is exactly what makes source material useful in an IB investigation.
2.3·Weakness
Page 8
This claim is important, but the student uses it too quickly as if national contribution automatically proves responsibility for the GPGP. The student should explain how the source estimates were produced and why they are valid for this investigation, especially since marine debris can travel across borders and is not always traceable to one state.
2.4·Weakness
Page 9
The sentence becomes conceptually unclear here, and the ecological chain is not expressed cleanly. The student should tighten the explanation of how turtles affect reef balance, because imprecise wording weakens confidence in the biology even when the underlying idea is relevant.
2.5·Strength
Page 9
The student shows solid understanding of the ecological role of sea turtles. This matters because it frames the species as more than just an affected organism; it justifies why harm to turtles has wider ecosystem consequences.
2.6·Weakness
Page 10
This is correct, but the explanation remains general. The student should link vulnerability to the specific forms of exposure in this essay—such as ingestion, entanglement, and migration overlap with debris fields—so the biology is used analytically rather than descriptively.
2.7·Strength
Page 11
This is one of the more effective applications of evidence because the student connects the migration map directly to exposure risk. The figure is not left as decoration; it is used to support the argument that turtle movement makes contact with the GPGP difficult to avoid.

Criteria Feedback
- You make several genuine analytical moves, such as interpreting debris data and discussing the limits of cleanup technologies.
- Your essay has a discernible structure and includes an attempt to build an interdisciplinary argument.
- You show some awareness of uncertainty, alternative explanations, and the limits of available data.
- The central argument is not consistently sustained, and the geopolitical section is not always tied back to direct evidence about turtle impacts.
- Several causal claims are stated too strongly without enough proof, especially where you connect tensions, policy delays, or military activity to pollution outcomes.
- Your conclusion is more assertive than the evidence fully supports, and the essay does not sufficiently weigh alternative drivers such as fishing activity, waste systems, and ocean circulation.
3.1·Weakness
Page 6
This statistic is relevant, but the student does not fully evaluate its significance for the research question. The essay should explain whether fishing debris is linked to geopolitics only indirectly, and whether it is stronger evidence for ocean governance than for a US–China causal relationship.
3.2·Suggestion
Page 7
The student could deepen the analysis by comparing why some sources dominate by count while others dominate by mass. That would help show more sophisticated thinking about how item number, material density, and source type affect the interpretation of pollution data.
3.3·Weakness
Page 12
This is an important causal claim, but it is asserted too strongly without direct evidence in the paragraph. The student should distinguish between a treaty’s long negotiation period and proof that US–China tensions specifically caused the delay, otherwise the argument risks overclaiming.
3.4·Weakness
Page 13
The causal link here is speculative. The student should show evidence that naval expansion measurably increases plastic pollution in the GPGP, or else qualify the claim as a possible contributor rather than treating it as established fact.
3.5·Question
Page 14
If cleanup is already limited by scale, technology, and funding, how much additional explanatory power do geopolitical tensions actually add? The student should ask whether diplomacy is the main barrier here, or whether physical and economic constraints are more important drivers.
3.6·Strength
Page 15
The student is beginning to evaluate cooperation as a reciprocal process rather than a one-sided problem. That is a good analytical move because it recognises that environmental action depends on political trust and mutual commitment.
3.7·Weakness
Page 17
The student makes a useful policy connection, but the explanation is too definite when it says these laws have “greatly reduced” waste entering the oceans. The essay needs evidence showing the scale of the reduction and a clearer chain from domestic law to ocean debris before drawing that conclusion.
3.8·Weakness
Page 18
This conclusion is under-supported because it compares changing waste output to population growth without showing the actual calculation or its relevance to GPGP pollution. The student should either provide the ratio explicitly or narrow the claim to what the cited policy evidence can genuinely prove.
3.9·Suggestion
Page 19
The student could improve evaluation by separating which tensions affect trade, which affect science cooperation, and which affect environmental policy. That would make the argument more nuanced and help prevent the geopolitical section from becoming a general history of conflict.
3.10·Weakness
Page 20
This sentence overreaches because demilitarisation is not shown to be the direct solution to GPGP plastic accumulation. The student should align the conclusion more closely with the evidence presented, for example by prioritising waste management, fisheries regulation, and scientific cooperation over broader geopolitical aspirations.

Criteria Feedback
- Your report has a clear overall academic structure with headings, a contents page, and a bibliography.
- You include visuals that are relevant to the topic and support the discussion in several places.
- Your work is generally navigable and the basic document requirements are met.
- Your in-text referencing and bibliography are inconsistent in format.
- Some visuals are not presented as cleanly or professionally as they could be, and a few figures are hard to read or contain visible artefacts.
- There are small structural issues such as mismatch between headings and content, which reduce polish.
4.1·Strength
Page 2
The document is easy to navigate because it includes a clear contents page and section headings. That structure helps the reader follow the progression from context, to biological impact, to geopolitical analysis, to conclusion and evaluation.
4.2·Weakness
Page 2
The table of contents does not accurately represent the section order here, because the later page 18 entry is a different discussion from the earlier sea-turtle section. The student should check that headings match the actual content so the structure remains transparent and professional.
4.3·Strength
Page 11
This figure is well chosen because it directly supports the migration argument and is clearly labelled with a source. Using a map here improves the presentation by making the spatial dimension of the investigation visible rather than leaving it abstract.
4.4·Weakness
Page 16
This figure contains a visible artefact that should be removed in the final version. Even though the content is otherwise useful, stray interface text weakens the professionalism of the page and distracts from the data being presented.
4.5·Weakness
Page 20
The conclusion is clearly signposted, but the evaluation is separated too far from the main argument. The student should consider integrating brief evaluative comments throughout the analysis so the final structure feels less like a descriptive section followed by a late reflection.
