Where should I stop for interest to kids when driving between Toronto and Boston? [closed]

I'm planning on driving with my family (2 adults, 2 kids - 8 & 6yrs) from Toronto to Boston in August taking up to 2 days. Since we are not in a huge rush, we would like to visit some places along the way that the kids might be interested in - probably parks/museums/attractions etc.

Off the top of my head looking at the map Niagara Falls seems like a prime contender, but having never driven this route before I those with better knowledge and experience may have better ideas of alternative.

As far a a route goes, I can obviously get one from Google Maps, but vacation planning by algorithm will probably not produce be the most interesting of times, which is where this site and it's dedicated and knowledgeable users comes in. It's not always the most direct route which takes one to the most interesting places.

What is the best route that we should take and where should we stop on the way - you know, for the kids?
