The student provides a focused and detailed description of the research question, specifying the organic acids tested and their concentrations while clearly outlining the method used to measure their effects on E. coli growth. However, the student fails to include a proper title for the investigation and only states one hypothesis without providing its alternative. The methodology employed is appropriate and well-structured, ensuring the validity and relevance of the results through controlled variables and preliminary trials. Furthermore, the student demonstrates a strong awareness of safety, ethical, and environmental issues related to the experiment, effectively addressing potential hazards and disposal methods.
