The student provides a clear and specific research question that identifies the independent and dependent variables, effectively guiding the investigation. However, the student fails to fully explore the background information, as the section lacks focus at times. The methodology is well-structured and suitable for addressing the research question, with appropriate steps to ensure the validity of the results and a strong awareness of safety hazards. While the student demonstrates an understanding of environmental issues related to the experiment, there is a lack of discussion regarding ethical concerns, particularly concerning the use of drinkable tea.
