Can we post questions asking for ideas on term papers and field work on specific topics? I didn't find any related open question. The one that I found was closed and was tagged 'opinion based'.
We get questions looking for ideas for science projects at all levels, from grade school teachers to university students, and these questions are almost all closed as either "Primarily Opinion-Based" or "Too Broad", depending on the question and how the close-voters interpret it. Questions asking for ideas for term papers (it's two words, not one) or field work would be just as off-topic.
