The student's investigation begins with a clear and detailed description of the main topic, focusing on the effect of increasing the size of the alkyl group on the bond angle around a tetrahedral carbon atom. The background information provided is relevant and well-organized, particularly in explaining the VSEPR theory and its impact on bond angles. The chemistry is explained thoroughly, aided by diagrams that enhance understanding. The methodology is appropriate for addressing the research question and includes steps to ensure the relevance and validity of the obtained results. However, the labeling of independent and dependent variables could be clearer. Notably, safety hazards, ethical concerns, and environmental issues are not relevant to this theoretical investigation.
