The student has provided a well-focused and detailed description of the main topic, which is to examine the effects of sodium bicarbonate concentrations on Young's modulus of a starch-based bioplastic. The research question is clearly stated without any errors. The student has provided relevant and focused background information and explained the chemistry involved in producing the bioplastic and calculating Young's modulus. The methodology of the investigation is highly appropriate and focused on answering the research question, with appropriate steps taken to assure the relevancy and validity of the results. The student is also fully aware of safety hazards, ethical concerns, and environmental issues that can arise during the experiment.
