The student provided a focused and detailed description of the main topic, emphasizing the importance of macronutrients for plant growth and citing relevant studies to support the investigation. However, the research question lacked clarity and explicit details on the experimental setup, which affected the overall focus. The background information provided was generally relevant but could have been more directly connected to the research question. The biology was explained well, making the roles of nitrogen, phosphorus, and potassium easy to understand. The alternative hypothesis lacked a clear explanation of the anticipated outcome based on plant biology. The methodology was highly appropriate and well-focused on answering the research question, but it could have included details on data analysis for statistical validity. The student demonstrated full awareness of safety hazards but could have provided a more comprehensive discussion of ethical and environmental concerns to strengthen those sections.
