From the Shedd Aquarium web site:

Dive in with Shedd Aquarium and other Chicago-area 6th- through 12th-grade students to explore local ecosystems while earning service-learning hours! Spend a day outdoors monitoring, maintaining and improving habitats so you, your community and our native animals all have green spaces to enjoy. Past Shedd Stewards events have included removing invasive plant species, followed by canoeing in the Skokie Lagoons.

Each Shedd Stewards event functions as a unique program, and within each program we incorporate different activities, focused on both stewardship and recreation. Specific program details will be sent to registered participants closer to each date.
