Shaanxi Nature Museum （East Gate）

This guide to the Shaanxi Nature Museum in Xi'an opens with a robotic dinosaur roaring behind glass and follows the museum's two halls under one ticket: a science wing anchored by a mamenchisaurus skeleton curling around a distant corner, and a hands-on technology wing where kids race marbles, chase their reflections through a mirror maze, and pedal a bulb-wired bicycle. Upstairs, a dome seats around one hundred seventy five people under the only planetarium screen of its kind in northwest China. You'll get a feel for a museum built to be played in, not just walked through.
