The student outlined the topic of their study at the beginning of the essay, clearly stating it as "Water retention capacity of different types of humectants," which effectively set the research focus. The investigation was firmly rooted in IB Chemistry syllabus topics, particularly relating to chemical bonding and molecular interactions. The student established a clear context by providing relevant background information on humectants, their mechanisms, and specific examples, while ensuring that the work remained focused on chemistry. The research question was well-defined, relevant to chemistry, and presented at the beginning of the essay, effectively guiding the investigation. However, the methodology section lacked sufficient detail for replication because it did not specify the exact quantities used in the experimental procedure. Overall, the student successfully obtained substantial relevant data from the experiments conducted.
