At Kent School, your work in the Science Department requires citation according to the APA style. APA stands for “American Psychological Association” and emphasizes the currency of information in its rules.
APA also has strict guidelines for margins, font, spacing, pagination, etc. Check whether your teacher expects you to follow all of these, and if so, look for an example paper at the Purdue OWL or in the ARC or Library.
This tutorial from the American Psychological Association includes step-by-step instructions for those who have no prior knowledge of APA Style.
