COSI Science Festival 2025

It’s the spring of STEAM at DCDL!

We’re a proud partner of this year’s 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 has planned lots of STEAM focused-programs this spring to bring the magic and learning of COSI to the Library. We’re also sponsoring Main Street Delaware’s May First Friday to bring the fun of science to the streets!

Join us on May 2 for First Friday in downtown Delaware for Mystery on Main Street: A Forensic Mystery Adventure. During this interactive adventure, sleuths of all ages can help us solve a crime — find the Little Brown Jug trophy that has vanished from the Library!

Explore downtown and use STEAM-based forensic activities to track down clues, analyze evidence, and find the Jug! With engaging stations featuring hands-on detective work, this is the perfect evening for families, aspiring investigators, and curious minds.

Can you crack the case? Put your detective skills to the test!
