The dinosaur museum at Thanksgiving Point is quite good! Great for kids as there are lots of hands on activities. DH and I had fun just by going by ourselves! A beautiful hike good for camping not too far from there is Dog Lake from the Mill...D? North Fork trail. The Mill (D?) South fork trail also goes to a cold waterfall called Donut Falls (the pouring water made a donut hole in a rock with a cave underneath after a long time - it's pretty cool, but you have to climb a little to actually get to the cave, not sure how appropriate that would be. It's not too hard, just cold, and not places really for camping there). These are all in the Salk Lake/Utah Valley area.
