The Academy of Natural Sciences Welcomes Spring with Two New Exhibitions, Earth Day Festival and More 

Calendar of Events AprilJune 2022 

PHILADELPHIA, February 25, 2022

This spring the Academy of Natural Sciences of Drexel University presents two new exhibitions and an Earth Day Festival with evening hours and special admission, as the nation’s oldest natural history museum continues a yearlong celebration of Water Year.


Extreme Deep: Mission to the Abyss, opening April 2, invites visitors to explore the mysteries of the deep sea, discover creatures no one knew existed until recently and experience the technology that allows scientists to travel to the bottom of the ocean. 


The River Feeds Back, opening June 1, is an immersive sound installation created by artists Annea Lockwood and Liz Phillips. The exhibit brings visitors into the deep sonic environment of the Schuylkill River watershed through recordings and a layered sound map that captures glimpses of the river system including the life of aquatic insects, eels, fish and swirling currents. 


The Earth Day Festival on April 22 will take place from 48 p.m. and admission will be pay-what-you-wish. Visitors can celebrate life on Earth and the systems that support it with a night of fun and interesting science programming, conservation conversations, craft beer and more. 


The Academy and Drexel’s Water Year celebration is designed to provide a fresh perspective on the water systems that bind us together and inspire us to work collaboratively to ensure clean and healthy water for natural systems and human communities. 


Here’s what’s coming up this spring. For details and the latest updates, visit 


Special Exhibit 

Invisible World of Water 

Through Sunday, May 1 


Invisible World of Water renews our appreciation for the vital element of water through artworks that combine the marvel and insight of both scientific and artistic inquiry. Centered around two micro-phenomena — snow crystals and diatoms — the exhibition presents parallel histories of observation and shows the interplay between the micro-cosmic and macro-cosmic. Invisible World of Water includes illustrations from rare books (by Robert Hooke, Christian Gottfried Ehrenberg and Ernst Haeckel); Victorian-era arranged diatom slides by Harold Dalton and others; microphotographs by Snowflake Bentley and Ukichiro Nakaya; artifacts documenting the groundbreaking research of Academy scientist Ruth Patrick; contemporary ceramic sculpture by Marguerita Hagan; stop-motion imagery by physicist Kenneth Libbrecht; and high-resolution photography by Nathan Myhrvold. The Invisible World of Water considers the hidden connections and the flow between water, land and air through Earth’s hydrosphere. 


Special Exhibit Gallery 

Extreme Deep: Mission to the Abyss 

Saturday, April 2 through Sunday, July 24, 2022 


Explore the mysteries of the deep sea, discover creatures no one knew existed until recently and experience the technology that allows scientists to travel to the bottom of the ocean in Extreme Deep: Mission to the Abyss. Newly discovered life forms, bubbling thermal vents, close-up views of compact research submersibles and shipwrecks including the Titanic, are among the attractions in this adventure developed in collaboration with Woods Hole Oceanographic Institution. Visitors will learn about the geological forces deep within the earth and how superheated water erupting from deep vents supports newly discovered life forms. The sun doesn’t penetrate the water at these depths, yet seafloor inhabitants thrive in total darkness thanks to a unique life support system. Extreme Deep reveals the secrets of the ocean and enriches our understanding of our connection to it.

Dietrich Gallery 

The River Feeds Back 

Wednesday, June 1 – Sunday, October 16, 2022 


The River Feeds Back, an immersive sound installation created by artists Annea Lockwood and Liz Phillips, will bring us into the deep sonic environment of the Schuylkill River watershed. Using recordings from sites along 135 miles of the Schuylkill and its tributaries including Wissahickon Creek, Lockwood and Phillips composed a layered sound map that captures glimpses of the river system above and below its surface, including the underwater life of aquatic insects, eels, fish and swirling currents. Participants will experience this dynamic sound work through a variety of listening portals spatially arranged throughout the Dietrich Gallery. Benches embedded with transducers will provide a visceral experience of the river, while hollowed tree trunks will transport listeners to the subaquatic worlds of the Schuylkill. A wooden table etched with a contour map activated by touch will pinpoint the artists’ recording sites. Free with museum admission.
