“Gray infrastructure is the system of pipes and ditches that channel storm water. Green infrastructure is the harnessing of the natural processes of trees and other vegetation — so-called ecosystem services — to carry out the functions of the built systems. Green infrastructure often intercepts the water before it can run into streets and become polluted and stores the water for gradual release through percolation or evapotranspiration. Trees also clean dirty water through natural filtering functions.Advocates say green infrastructure isn’t just about being green — it makes financial sense, as well. Its cost-effectiveness depends on how benefits are assigned and valued, and over how long a time scale, but green has been shown to be cheaper than gray.”

2016 was a big year for Illinois-Indiana Sea Grant! From award-winning work to hands-on field experiences for students, community events on Lake Michigan, and strong partnerships across the region, IISG was busy advancing Great Lakes science, education, and stewardship every step of the way.
Reminisce with us on all things 2016 at the link in bio.
Ripple Effects is a collection of 8 activities for grades 6–12 that introduces students to aquatic invasive species in the Great Lakes.
Through research, reporting, and role-playing games, students will:
✅ Explore how non-native species arrived
✅ Understand why they threaten native ecosystems
✅ Investigate their impact on the Great Lakes
Aligned with Next Generation Science Standards and Great Lakes Literacy Principles, this curriculum is perfect for engaging students in real-world science and stewardship.
