The student clearly stated the independent variable, average bond length, and the dependent variable, energy difference of d-orbital splitting (ΔE), in the research question, allowing for a direct investigation of their relationship. The methodology was well described, including the use of a UV-vis spectrophotometer to analyze ΔE, and the student provided a thorough background theory relevant to the investigation. Controlled variables were identified and explained, while safety, ethical, and environmental considerations were appropriately addressed. The methodology was detailed and precise, ensuring that it would be reproduced, and there was no irrelevant or repetitive information included.
