Last Chance to Discover Wild Music

Whales compose, bullfrogs chorus, songbirds greet the dawn, and people everywhere sing and dance. What do we all have in common? Find out at our summer exhibit, Wild Music: Experience the Sounds and Songs of Life, which leaves the EcoTarium after September 6!

Discover how nature is filled with “musicians” that create distinct musical masterpieces to communicate with and relate to one another. And, explore how human music is inspired by the music of other living creatures – from tiny insects to giant whales. Wild Music offers unique experiences to see, hear and feel sounds!

Soundtastic Saturdays -- every Saturday afternoon at 2:30 p.m.
During this special weekly Science Discovery program, learn about how animals perceive and produce sounds, or explore instruments and other tools humans use to create tones, rhythms and music.

You Won't Believe Your Eyes

Discover unseen worlds and hidden dimensions beyond our normal vision to uncover the mysteries of things too fast, too slow, too small or simply invisible in the film Mysteries of the Unseen World, now playing in the Alden Digital Planetarium: A National Geographic Theater.

The film, narrated by Forest Whitaker, uses innovative high-speed and time-lapse photography, electron microscopy, and nanotechnology, to transport audiences to an enthralling secret world of nature, events, and breathtaking phenomena not visible to the naked eye.

Mysteries of the Unseen World is now playing daily at 3:00 p.m. Tickets can be purchased at our Tickets and Information Desk on the day of your visit.

Mysteries of the Unseen World is presented locally by Unum.
