The student has demonstrated a focused and detailed description of the main topic, clearly outlining the investigation of the reaction rate of varying concentrations of household bleach on blue food dye. The research question is detailed, including the independent and dependent variables, their units, and the experimental technique. Additionally, the background information provided is relevant and complete, encompassing previous studies, bleach properties, absorbance measurement, main reactions, and reaction rates. The student has also explained the chemistry behind the experiment effectively, ensuring the reader's full understanding without the need for rereading. The chosen methodology is highly appropriate and focused on answering the research question, allowing for the calculation of reaction rates and ensuring the relevancy and validity of the obtained results. Moreover, the student has shown full awareness of safety hazards and environmental issues, although there is a need to acknowledge the absence of ethical concerns due to no living organisms being used in the experiment.
