Learn how the museum's new interior roads will help improve the
DuPage River watershed. Take a 2 p.m. guided tour on Sunday of the

beneficial type of garden. Visit activity stations and make a Soil
Sammy, Garden in a Glove and Dissect a Seed; pump water from an old
fashioned pump connected to cisterns; and watch demonstrations that
