The Museum of Natural Science has a lot of different exhibits (each one requires the purchase of a separate ticket).
Currently they're showing the Lord of the Rings exhibit (which is only in 3 locations in the entire U.S.) so I think that's definitely worth seeing if you're a LOTR fan.
As for the other exhibits, I found them to be boring and there were plenty of things that you wouldn't want your child touching.
If you have a toddler that loves to touch everything in sight (like mine), you'll spend the entire time saying, "No."
There's really not much for kids to do here but it's worth a visit if you have no children and you're new to the area.
