The student provides a focused and detailed description of the aim of the experiment, which is to determine the effect of different temperatures on the rate of reaction of zinc with hydrochloric acid. The research question is also present. The background information provided is relevant and focused, but could have been expanded. The chemistry is explained well enough for the reader to easily understand it without the need for rereading. The methodology of the investigation is highly appropriate to the topic and focused on answering the research question. Although there are some controlled variables listed, their potential effect on the results is not described and some essential factors are missing. The student shows full awareness of safety hazards and environmental issues that can arise during the experiment, but no ethical concerns or lack thereof are stated.
