You and the kids will want to keep coming back to the Arizona Science Center again and again to visit the familiar standard exhibits, but also to check out the new films and the special traveling exhibits. Some exhibits require an additional fee. For example, Body Worlds was a specially ticketed exhibit that attracted thousands of adults.
One of the most popular traveling exhibits is Animal Grossology. If it's disgusting, and probably shouldn't be discussed at the dinner table, you'll learn about it here--ooh, gross! That's why the kids love it!
