Spend a day with your family at the Museum of Nature and Science in Dallas.  Your Explorer's Package includes 4 exhibit tickets, 4 IMAX theater tickets,  and 4 Planetarium tickets.  You can enjoy "the science of...Spying.  Do you have what it takes?" exhibit (which has been extended through April 11, 2010), see "Dinosaurs:  Giants of Patagonia" on the massive domed IMAX screen, and discover the beauty of the Texas night sky at the Planetarium. 

Your children will have so much fun they won't even realize how much they're learning along the way!
