What age groups of children would be most appropriate for this museum? (Hands on are for younger kids or more of a 'reading and looking' for middle school age?)

I would say it would be appropriate for 3rd graders and up, the tour guide explains what happened in each site that you visit, and he gives you a couple of minutes to read things that are in the house or how the slaves lived at that time. I think it opens the door for a parent to educate the kids about slavery. Very good

Yes I would read 3rd grade and up they would be a great adventure for them

There are no hands on exhibits. It is a walk, read and look experience.
