The student demonstrates a focused and detailed description of the main topic by stating their aim to determine the antibacterial properties of a combination of essential oils. They also provide relevant background information of the bacterial and plantar species used in this investigation. The student explains the science behind the different investigation components, such as agar plates and bacterial species, in a way that is easily understandable. The methodology used, including the use of agar plates and paper discs to measure inhibitory properties of essential oils, is highly appropriate and focused on answering the research question. The student also demonstrates full awareness of safety hazards, ethical concerns, and environmental issues that can arise during the experiment.
