New Holiday Traditions

Due to the upgrade of our Explorer Express Train and its tracks, we are sorry to say that we are not able to hold our annual holiday event, A Christmas Journey, this year.

Join us on Wednesday, December 31, for Noon Year's Eve. The day is full of festivities that the whole family can enjoy. We will hold New Year's Eve countdowns at 12:00 p.m. and 2:00 p.m., as well as create and toast resolutions, make 2014 time capsules, and more!

Activities are free with EcoTarium admission.

Discover the Unseen World this Holiday Vacation

Join us for Days of the Unseen World. During Holiday Vacation, our Science Discovery programs will be themed around our newest National Geographic planetarium film, Mysteries of the Unseen World.

Explore how scientists uncover things not visible to the naked eye. Experiment with time lapse photography and interact with an infrared thermal camera that exposes a fascinating form of invisible light.

While you’re here, be sure to see the film in our Alden Digital Planetarium: A National Geographic Theater to take an extraordinary journey into the hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible.

New Exhibit! KEVA: Build It Up!

KEVA: Build It Up! stimulates the imagination. These uniform maple planks provide an easy, non-messy way to explore sculpture and design, form and function.

Build structures simply by stacking the planks. No glue, no connectors, just simple engineering and improvisation. This exhibit turns artists into scientists and scientists into artists. KEVA planks inspire the whole family to enjoy building together. 

KEVA: Build It Up! is sponsored by Gorman Richardson Lewis Architects.
