` ==Please be careful== Wikipedia chemistry has had an uneven experience with these homework assignments. See this discussion Wikipedia_talk:WikiProject_Chemistry#New_articles_from_a_class_project.  Some suggestions: *Wikipedia chemistry is delighted to have new contributions, feel free to ask for help. *Wikipedia does not exist to support homework and all content risks revision and even deletion - happens to all of us.  *Quality of contributions to Wikipedia is often inversely proportional to length, and most of the best contributions to this forum are brief. *Contributions related to human health are always encouraged to review WP:MEDRS.   *Students and especially Wikipedia both benefit when content is supported by reviews and books per WP:SECONDARY.  Inexperienced students often cite primary journals but they might lack the expertise to select such sources judiciously.  Best to avoid them.  It is very bad idea to require each student to add a fixed number of references - Wikipedia editors prefer emphasis on quality vs quantity. *Students are encouraged to add material incrementally, vs dropping an ``essay bomb`` on articles.  Students will get better feedback from the community of editors. *Per the chemistry MOS, chemistry articles emphasize chemistry, not safety, since safety is authoritatively covered in the MSDS.
