The student provides a focused and detailed description of the main topic, clearly stating the aim of the experiment to investigate the effect of temperature on the oscillation pattern and duration of a BZ non-linear chemical oscillator. The student also includes a focused and detailed description of the research question. The background information provided is relevant and well-organized, explaining the BZ reaction, its properties and mechanism, as well as relevant chemical concepts. The chemistry is explained well enough for the reader to understand without the need for rereading. The methodology of the investigation is highly appropriate to the topic, focusing on answering the research question and including steps to assure the relevancy and validity of the obtained results. The student also shows full awareness of safety hazards and environmental issues that can arise during the experiment. However, the student should have shown awareness of ethical concerns associated with the methodology or materials used in the investigation.
