This ongoing program runs from 11 a.m. to 2 p.m. Tuesday, July 26, to Saturday, July 30.

Each day this week is dedicated to digging into one aspect of our geological past. Attend one program, stop by for a couple or join us every day this week to learn all about fossils. These are drop-in programs; come anytime between 11 a.m. and 2 p.m.

Check out the daily schedule:

• Tuesday, July 26: What’s Underneath? Sedimentary, metamorphic, igneous – what type of rock is under our feet in Will County? Learn some geology basics with rock and mineral samples.
• Wednesday, July 27: Name That Fossil. Discover fossils and learn how they are made and how to identify local specimens with fossil games and by making your own fossil rubbings!
