The water section houses Dora the axolotl, our aquatic amphibian, and the long-time favorite water table. Enjoy a 270 gallon saltwater aquarium with a raised platform for 360° viewing. You can use large blue foam building blocks to make anything from a robot to a castle. The only limitations are within your imagination! 


Walk inside our hollow tree animal clinic where you can care for woodland animals.  Peek in at the Madagascar hissing cockroaches and rainforest cockroaches. Examine 3D objects more closely with our large screen microscope. Delight your senses as you make music and feel textures of natural items. Play-act in the shadow theater using one-size-fits-all animal costumes.  


The most prominent feature is the two-story rocket, complete with an emergency escape slide and interactive computer control panels that allow you to communicate via a NASA inspired Capcom station. Create constellations, real or imagined, in the star room and launch a shuttle from Earth to a moonscape table. A solar system mural spans the back wall, along with a projection of the moon that updates daily with the current moon phases.  

New Activities

The activity tables in the center of the room have a variety of hands on experiences for all ages.  Activities change on a regular basis, so look here for something new on your next visit.  Offerings vary and may include science experiments, making, math challenges, and puzzles.

Staff Facilitation 

Early childhood staff are available to assist play and learning during Discovery Room sessions.  We encourage adults to immerse in play with their children.
