The science center also has an exhibition featuring Teenage Mutant Ninja Turtles.

Budding oceanographers and marine lovers can dive into the undersea world right here in Columbus, courtesy of “Unseen Oceans,” the latest COSI exhibit.

“Unseen Oceans” is a new exhibition produced by the American Museum of Natural History. Columbus is the exhibit’s first stop outside of New York City before it heads overseas, says Jaclyn Reynolds, director of communications for COSI.

“Unseen Oceans,” which opens Oct.19, is the latest companion exhibition to the AMNH Dinosaur Gallery at COSI. As they travel through the galleries, visitors will learn about the technology being used to explore the oceans, see fossil replicas (including a megalodon tooth), explore a partial replica of a Triton submarine, and discover the work of Ohio researchers. Topics include: plankton and the vital role they play in the ecosystem; ocean inhabitants, including giant creatures and those that glow in the dark; ocean research; and ocean habitats, through an immersive theater presentation.

“Unseen Oceans” answers such questions as how blue whales spend their day, what goes on in the deep waters around Hawaii, and what selection criteria can help identify protected marine areas, according to COSI. Exhibit-related information and worksheets for educators and students are available at cosi.org/exhibits/unseen-oceans.

Note that “Unseen Oceans” has a $5 add-on fee for nonmembers. The exhibit runs through Feb. 2.

Teenage Mutant Ninja Turtles

COSI’s other new addition, “Teenage Mutant Ninja Turtles: Secrets of the Sewer,” takes visitors on a journey to learn more about Leonardo, Michelangelo, Raphael and Donatello while learning practical skills along the way.

The exhibit, modeled on the New York City sewer the crime-fighters inhabit, features brain teasers, trivia puzzles, and team-building challenges that include mazes, obstacles and more.

The traveling exhibition runs through Jan. 5 and is included with standard admission. It was produced by The Children’s Museum of Indianapolis and Nickelodeon.

New Onscreen

Two new movies have debuted in the National Geographic Giant Screen Theater: “Turtle Odyssey” and “Oceans: Our Blue Planet.” The latter, which was shown at COSI several years ago, concludes its run Nov. 17.

Upcoming films include “Rocky Mountain Express” (Nov. 20-24), “Tiny Giants” (Nov. 27 to Dec. 13) and the annual special engagement of “The Polar Express” (Dec. 14-15).

New planetarium shows include “Life: A Cosmic Story” through Nov. 12 and “Planetary Treasure Hunt” through Dec. 10. Up next: “Expedition: The Red Planet,” which will be shown Nov. 13 through Feb. 4.
