Although similar assessment criteri

Although similar assessment criteria apply to all extended essays in the experimental sciences, for a biology extended essay, the touc chosen must allow an approach that distinctly relates to biology. Where a topic can be approached from different viewpoints, the treatment of the material must be clearly biological. For example, an extended essay in an interdisciplinary area such as biochemistry will, if registered as a biology extended essay, be judged on its biological content, not its chemical content.
