Chicago Academy of Sciences Logo

Do you ever wonder how a butterfly gets its colors? Or how turtles hibernate? Do you wonder how birds know where to migrate each year? For over 160 years, the Chicago Academy of Sciences / Peggy Notebaert Nature Museum has served a unique role in the city of Chicago connecting children of all ages to nature and science through immersive exhibits, fun family events, important conservation research and in-depth education programs, inspiring the wonder in all of us.


We gratefully acknowledge the support of the Chicago Park District on behalf of the citizens of Chicago.
