The student has demonstrated a clear understanding of the relevant chemical principles and concepts, effectively applying them in their research on the biodegradability and tensile strength of bioplastics. The essay includes a clear explanation of the choice of techniques, apparatus, and chemistry behind the research question. Additionally, the student has incorporated relevant and appropriate source material and provided clear explanations for technical and subject-specific terms. However, there are areas for improvement, such as the need to paraphrase information from source material and to use more accredited scientific sources. The tone and style of writing should also maintain an academic and analytical level throughout the essay.
