The student demonstrates consistent and correct use of mathematical notation, symbols, and terminology throughout the investigation, particularly in representing vectors and energy output variables. They also provide detailed explanations for additional terms, such as angles created by the sun and the impact of clouds. Multiple forms of mathematical representation, including diagrams, tables, graphs, and formulae, are appropriately utilized to demonstrate data. Furthermore, the student effectively employs deductive methods and logical proofs in their exploration. However, there are areas for improvement, as key terms/variables are not consistently defined and explained when first introduced, and the degree of accuracy for rounded values is not consistently stated. Additionally, the labeling of graphs, tables, and diagrams needs to be addressed for clarity.
