The student clearly states the independent and dependent variables in the research question, identifying the type of soil as the independent variable and germination success, stem length, and biomass as dependent variables. The methodology is described sufficiently, detailing steps and materials to allow for reproducibility, and there is no irrelevant or repetitive information included. However, the student does not provide a clear explanation of the techniques used for measuring the variables or the sampling technique applied, nor do they discuss the rationale behind the number of trials and precision of measurements. Additionally, while the student addresses safety and environmental issues, they need to improve their discussion on ethical concerns regarding soil sourcing and the control of variables in their experiment.
