The student provides a well-written and organized background information section that explains how surfactants and sodium chloride interact. They clearly explain the chemistry of the experiment, including how micelles form and the ionic charges in those. The methodology of the investigation is highly appropriate to the topic and includes appropriate steps to assure the relevancy and validity of the obtained results. The student correctly identifies the independent and dependent variables to pursue the posed research question. However, the student does not show any awareness of safety hazards, ethical concerns or environmental issues associated with the experiment.
