COSI Science Festival
It’s a spring of STEAM at DCDL!
Join us April 29 – May 2, 2026 for the COSI Science Festival!
Science is everywhere, and science is for everyone. The COSI Science Festival builds a diverse STEAM workforce and closes the STEAM skills gap by exposing individuals to science and technology where they live, learn, and lounge. DCDL will feature STEAM-focused programs this spring to bring the magic and learning of COSI to the Library. We’ll also sponsor the Main Street Delaware May First Friday to bring the fun of science to the streets!
On Wednesday, April 29, join us at the Liberty Branch Library at 6:30 p.m. to Learn About the Moon Landing from Whiz Bang Science: A COSI Science Festival Event!
Then, head to downtown Delaware on Friday, May 1 for First Friday in downtown Delaware where you’ll be Inventing America: 250 Years of STEAM with Main Street. Look forward to engaging stations featuring hands-on experiments inspired by the discoveries and innovations of American inventors — the perfect evening for families, aspiring scientists, and curious minds.
It's the Spring of STEAM!
