Now Playing: Mysteries of the Unseen World

Through our exciting new partnership with National Geographic, we are delighted to show Mysteries of the Unseen World in our Alden Digital Planetarium: A National Geographic Theater.

Mysteries of the Unseen World, presented by National Geographic Entertainment and Day's End Pictures, takes audiences on an extraordinary journey into unseen worlds and hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible.

You can see the new show at 2:00 p.m. on Saturday and Sunday and 3:00 p.m. Tuesday-Friday. Tickets are $5 each (plus EcoTarium admission)/$4 EcoTarium members. Tickets can be purchased at the Tickets & Information Desk on the Upper Level of the museum.

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.

Nature Explore is Open!

Our new outdoor exhibit features several play areas, each with its own theme. From the Nature Art Area to the Dirt Digging Area to the Climbing and Crawling Area, and more, there is something for every family to enjoy.

The Nature Explore® Outdoor Exhibit is sponsored by Harvard Pilgrim Health Care and UniBank. Nature Explore is a collaborative program of Arbor Day Foundation and Dimensions Educational Research Foundation.
