Criteria A: Focus and Method

4/6

Criteria StrandsPro

A.1Topic identification and communication

Good

A.2Research question formulation

Good

A.3Methodology selection and justification

Good

Criteria Feedback

You chose a clear, interdisciplinary topic with a real-world case study that gives the investigation focus and relevance.
Your research question is explicit and comparative, which makes the direction of the inquiry easy to follow.
Your method is appropriate for a literature-based investigation and shows awareness of practical and ethical limits to primary research.

The comparison would be stronger if you defined exactly what you mean by environmental sustainability before beginning the analysis.
The scope is still a little broad because different sunscreen formulations and active ingredients are grouped together in ways that blur the comparison.
The method would be more convincing if you had named databases, search terms, and clearer inclusion/exclusion criteria.

Criteria B: Knowledge and Understanding

6/6

Criteria StrandsPro

B.1Source material selection and relevance

Good

B.2Knowledge demonstration and application

Good

B.3Use of terminology and concepts

Good

Criteria Feedback

You demonstrate strong understanding of both the chemistry and biology involved in coral exposure to UV filters.
You use scientific terminology accurately in most places and generally explain it clearly for the reader.
You apply concepts rather than just defining them, especially when linking chemical properties to biological outcomes.

Some broad claims are simplified too far, especially where different mineral sunscreen formulations are treated as if they all behave the same way.
A few explanations would be stronger if you qualified them more carefully, particularly around particle coating, size, and photocatalytic behavior.
The investigation would benefit from more consistent discussion of how measured concentrations affect interpretation across several studies, not just one.
