Science Behind STEAM-Powered Saturday

STEAM-Powered Saturday explores science, technology, engineering, arts and math through a wide variety of hands-on activities! Dig deeper into the scientific concepts behind these activities with these resources for kids and families--whether you came to our event or not.

We're so excited for this year's event on Saturday, October 3, 2026 at Harold Washington Library Center (400 S. State St.) from 11 am to 3 pm. 

This year, we're focusing on building the change by exploring conservation and nature.

Frogs

  • Did you know that there are 4 kinds of frogs common in the Chicago area? The Field Museum shares more information about these species including what their eggs look like.
  • Frog and Toad don't behave like real frogs and toads do, but they are still a great way to get kids interested in the real animals.

Nighttime in the City

Illinois and Chicago are home to many different creepy, crawly (but sometimes cute!) nighttime critters. On a given night, one might hear the low hoot-hoot of a Great Horned Owl or look outside and see a possum or raccoon crawling across the street looking for food. What nocturnal animals do you see in your neighborhood? 

  • Read about urban wildlife you could spot on your next outing.
  • The Illinois Department of Natural Resources put together this fun informational guide about the many, many critters we can find in our communities. Visit your library if you want to print out the coloring pages.   
  • Light pollution is a real issue in our cities, but it's easy to fix. Learn more about how it works and how the City of Chicago is helping!

Thanks to our partners for supporting this great day!
