An Extended Essay in Biology allows you to apply biological theory through the exploration of living organisms and life processes. The research will ideally involve the collection of primary data e.g. experimentation and fieldwork, although you can base your essay on the analysis of data and information from literature. The consideration of the ethical guidelines found on the research support page is especially relevant for Biology essays.
