A wonderful place to bring children.  On the small side and can get crowded.  The 1st floor features a children's 'submarine', a tree house/fort, lobster boat, trolley car, dinosaur digs, international dance on screen exhibit, play with gears, the "Post Office", flight test launcher and supervised crafts are some of many activities.  The upper floor has a story time area, and a play area for rug rats with a large train set. Parking can be a problem.  Try to find some behind the museum down the adjacent street.
