Ideas for Initial Photos

We are about to take some photographs, though unfortunately we have been limited to our classroom. We are going to take some different shot's using this location restriction.

For an extreme close up I might take some of of the piping or wiring in the room, maybe some of the engraved writings in the old science work tops,  for a close up I could do one of the many switches or electrical boxed in the room, maybe some of the science weights on the floor or something interesting.

I will try a variation of shot lengths and look around the classroom to find inspiration, but above are some ideas. Something that perhaps shows a purpose of the classroom, the people who have been in it, what makes it work as a classroom.
