Included with General Admission!

Saturday, April 13
9:00 am-6:00 pm

Join us for a celebration of all things Earth! During our fourth annual Earthfest, we will explore the time scales between weather and climate and examine the science behind climate change. Participate in citizen science projects, view art pieces that spark discussion, and meet with climate change experts. By reflecting on our day-to-day choices with an eye towards the future, we have the power to make the biggest impacts.

Members attend for FREE! Not a member? Adler memberships give you access to special events, discounts, and more. Become one today!

Learn About Climate Change With Our Feature Partner ¡Descubra!

Descubra - Meet the Science Expert at Adler Planetarium Earthfest!

¡Descubra! is a program from the Smithsonian Latino Center that combines STEAM (Science, Technology, Engineering, Art, and Mathematics) hands-on activities with informal conversations with featured speakers and collaborating organizations. 

Exploring the Effects of Climate Change on Ocean Waters and Currents

In this activity, visitors will learn about the effects of rising temperatures and their effect on ocean currents by measuring water salinity. Using a handheld hydrometer, visitors will measure salinity of “Caribbean” waters and “Artic” waters, learning how salinity affects water density, the engine that runs world ocean currents. Visitors will also learn how melting glaciers’ affect ocean currents, sea levels, as well as the geographic locations of communities, including the Latino community, across the United States.


10:30-12:00 pm
2:00-3:20 pm

Guests are invited to ask questions to our on-hand climate scientist, Astrid Caldas! Astrid is a senior climate scientist at the Union of Concerned Scientists working on climate change adaptation and science communication. She’ll be available throughout the day to take your questions and talk about climate change!


Be kind to our Earth and recycle your spare plastic shopping bags at Earthfest for the opportunity to be included in a community art project by artist Aymar Ccopacatty that recycles plastic bags into a woven art piece. (Don’t worry, we’ll have materials on hand if you don’t bring your own!)

Additional Programming Includes...

Chicago Botanic Garden: Budburst

Learn how to become a citizen scientist by observing plants with Budburst, a project of the Chicago Botanic Garden! Join the Chicago Botanic Garden team in the Solar System gallery as they walk through a Plant Phenology Wheel and Plant Guess Who!

California Academy of Sciences: Expedition Reef

Learn the secrets of the “rainforests of the sea” as you embark on an oceanic safari of the world’s most vibrant—and endangered—marine ecosystems, presented by The Chicago Academy of Sciences.

Loss of the Night

Learn about the Loss of the Night App through visuals and conversation. Join us outside on the terrace to explore with the app and apply your findings to further findings and questions.

Meet Northwestern University Experts

Explore cutting edge research from scientists around climate science and climate change by visiting our working laboratory. Experience interactive and immersive visualizations in our Space Visualization Lab and speak with related researchers featuring these visualizations.

Environmental Graphiti

This art project uses art to dramatize the effects of climate change to expand public awareness and make the science behind climate change more accessible. Guests will be able to view artworks from Environmental Graphiti on display, as well as make their own creations from climate change data in a family-friendly art activity.
