The outcome of the research should be a coherent and structured piece of writing that effectively addresses a particular issue or research question and arrives at a particular, and preferably personal, conclusion. Treatment of the topic, an extended essay in chemistry may be based on literature, theoretical models or experimental data. Moreover, it may help if the student further defines and refines the topic chosen for study in the form of a research question or statement. The scope of the topic and the research associated with it should enable all the criteria to be addressed.

Since chemistry is an experimental science, students are strongly encouraged to undertake experimental work as part of their research, although this is not compulsory. Essays written at the level of a newspaper or news magazine article are unlikely to achieve a high mark. The way in which the investigation is undertaken will depend very much on whether or not the essay contains experimental work performed by the student.

Where possible, the quality of sources accessed or data generated should be verified by secondary sources or by direct calculations. Criterion B: introduction, the purpose of the introduction is to set the research question into context, that is, to relate the research question to existing knowledge in chemistry. It is usually appropriate to include also the underlying chemical theory required to understand how the research question has arisen. Intellectual initiative: Ways of demonstrating this in chemistry essays include the choice of topic and research question, and the use of novel or innovative approaches to address the research question.

They should distinguish between primary sources (original scientific publications, personal communications, interviews) and secondary sources (textbooks, newspaper articles, reviews and show awareness of how reliable these sources are.
