At the sustainably designed Perot Museum of Nature & Science (perotmuseum.org), the skeletons of a Tyrannosaurus rex, Alamosaurus and other massive dinosaurs steal the show, though there’s much more to explore across the five floors of interactive exhibits. Among the many highlights, you can pilot a red-tailed hawk through a canyon valley on a bird flight experience, head into outer space while learning about our solar system, and peer into a working lab as paleontologists prepare fossils fresh from the field. As befits the Dallas location, there’s lots about energy extraction and future technologies – like cars powered by hydrogen fuel cells. For an extra $8, you can watch a movie in the 3D theater.
