Wonderful Waters

Learn about water on our planet at the Wonderful Waters exhibit as you scoop and pour water into the city’s reservoir, on a mountaintop, or in the rain cloud. Observe an axolotl (a Mexican salamander), in her freshwater environment, and discover life on the reef in our saltwater aquarium. Be sure to say hello to Dory and Nemo while you’re there.

Space Rocket

Assume the role of a NASA engineer on earth, or climb aboard the Harmony rocket ship and prepare for liftoff! Keep in touch with Earth on the TV screen and microphone as you simulate flying to the moon, Mars, or beyond. When you touch down back on earth, exit the rocket on a slide.
