I'm not sure about your kids, but the children's museum wouldn't hold my kids interest at age 11 and 14 (it's a great Children's Museum but more for younger kids).
With the hot weather I would definitely want to plan some things by water/pools which is why I suggested looking into Lake Michigan towns, as you have 5 days to fill, Indy might be good for 2 or 3 days, but it's a quick drive up to the lake for a change of scenery. My kids had a blast hitting the beach on Lake Michigan, walking around the towns etc, they are happiest outside and with their feet in the sand, swimming, building sand castles, walking the shore looking for creatures etc.
